Modern metal-forming operations require more than nominal pressing force. A production press must combine structural rigidity, dependable motion control, practical die access, repeatable accuracy, operator protection, and long-term serviceability. The BLPS-45 Robust Large-Capacity Open-Gap Deep-Throat Power Press is designed around these requirements. With a nominal capacity of 450 kN, an enlarged 850 × 440 mm worktable, a deep-throat open-gap structure, a 4 kW main motor, and integrated hydraulic overload protection, it provides a balanced solution for demanding stamping, forming, bending, blanking, and medium-duty forging applications.
The machine is developed for manufacturers that need greater working access than a conventional closed-frame press can provide while still requiring the rigidity and controlled performance associated with industrial precision equipment. Its reinforced welded-steel frame, heat-treated structural components, carefully matched drive system, and sensitive dual-solenoid control architecture support stable operation during repeated production cycles. These characteristics make it suitable for general metalworking plants, component manufacturers, fabrication workshops, appliance production, agricultural machinery suppliers, automotive subcontractors, and other industrial users.
Unlike a basic mechanical press designed only around force output, the BLPS-45 is configured as a complete forming platform. Its open-gap deep-throat arrangement improves access to the working area and accommodates larger or longer workpieces. The enlarged table provides useful space for dies, fixtures, guide components, and positioning equipment. At the same time, the machine’s reinforced body helps minimize elastic deformation when the press operates under significant loading.
The BLPS-45 belongs to the open-gap deep-throat power press category. Its principal function is to convert the rotary motion of the main drive into controlled reciprocating slide movement, allowing the upper die or punch to apply force to a workpiece placed on the lower die. The press is intended for applications in which a consistent mechanical stroke, stable pressure generation, and repeatable stopping performance are essential.
The 450 kN nominal capacity gives the machine a substantial working range for medium-duty industrial forming. Actual application suitability depends on material type, thickness, die design, forming method, contact position, and required force curve. When properly matched with the tooling and production process, the press can support operations such as shallow drawing, blanking, punching, bending, coining, embossing, trimming, straightening, and selected forging processes.
The deep-throat configuration is one of the product’s most important functional characteristics. A greater throat depth allows the operator to position workpieces farther into the frame, which is especially useful for components with extended flanges, large surface areas, or forming features located away from the material edge. This design can reduce the need for multiple repositioning steps and may allow a single press cycle to perform work that would otherwise require a smaller machine and additional handling.
The open-gap frame also improves accessibility. Operators can approach the die area from the front and, depending on the overall production layout and safety arrangement, may benefit from improved side access compared with a fully enclosed frame. This is valuable during die installation, fixture adjustment, maintenance, inspection, and production changeover.
The following specifications summarize the listed BLPS-45 configuration. Because power presses may be supplied in different vertical or horizontal configurations and with application-specific options, the final technical data should be confirmed against the order specification, tooling requirements, and applicable safety standards.

The combination of a 90 mm slide stroke and a 50–95 strokes-per-minute operating range gives the BLPS-45 useful flexibility. A longer slide stroke can provide sufficient clearance for loading, unloading, and die movement, while the adjustable production speed range allows users to select a suitable balance between output, material handling, forming requirements, and tooling life.
Frame rigidity directly affects the performance of a power press. When a frame deflects under load, the slide and die may not remain perfectly aligned. Excessive deformation can affect dimensional accuracy, increase tool wear, create uneven contact, and reduce the useful life of bearings, guides, and other moving components. The BLPS-45 addresses this challenge through a reinforced welded-steel frame structure developed for high-load operation.
The welded construction allows the frame to be engineered as an integrated load-bearing structure. Rather than relying solely on separate cast or bolted members, the frame can be designed with carefully positioned plates, ribs, reinforcements, and load paths. This helps distribute pressing forces across the body and reduces localized stress concentration. The resulting structure is intended to maintain stable geometry during repeated cycles.
Heat treatment is also important in a welded machine body. Welding introduces thermal stresses that may influence dimensional stability if they are not properly controlled. A suitable heat-treatment and stress-relief process helps reduce residual stress before final machining and assembly. This contributes to more consistent alignment between the frame, slide, worktable, and guide system.
For the end user, the benefit is not limited to a stronger-looking machine. A stable frame supports repeatable die engagement and helps the press maintain predictable performance over extended production periods. It can also provide a more dependable foundation for precision tooling, especially when the workpiece requires close dimensional control or when production involves many repeated cycles.
The reinforced body is particularly valuable in applications where the material resistance changes during the stroke. Blanking and punching may generate sudden load peaks, while bending and forming can produce varying resistance as the workpiece changes shape. A rigid frame helps the machine respond to these changing loads with less unwanted movement.
BLPS-45 Robust Large-Capacity Open-Gap Deep-Throat Power Press
The open-gap deep-throat arrangement distinguishes the BLPS-45 from many conventional compact presses. In a standard shallow-throat machine, the usable forming area may be limited by the distance between the front working zone and the rear frame. This can restrict workpiece size, fixture placement, and the location of forming features. A deep-throat layout extends the practical reach of the press and gives manufacturers more freedom when designing tooling.
For parts with a large blank diameter, long flange, deep offset, or wide panel, the additional throat capacity can simplify production. The operator may be able to position the component more deeply into the machine rather than rotating it repeatedly. This can improve handling efficiency and reduce the risk of inconsistent positioning between cycles.
The design is also advantageous for specialized dies. Deep-reach dies, compound tools, progressive fixtures, and custom forming arrangements may require additional space behind the working centerline. The BLPS-45 offers a more adaptable platform for such tooling than a small general-purpose press with limited throat clearance.
Open-gap architecture can improve visibility as well. Clear visual access to the die area helps operators confirm workpiece placement, observe material movement, identify abnormal conditions, and perform first-piece inspections. Visibility does not replace guards, interlocks, or approved safety systems, but it can support more effective operation and maintenance procedures.
Deep-throat capability must always be considered together with load distribution. The farther a forming force is applied from the ideal load center, the greater the potential for frame deflection and uneven loading. The BLPS-45’s reinforced structure is therefore especially relevant: the machine is not simply offering more reach, but combining extended reach with a frame engineered to support demanding industrial use.
The 850 × 440 mm worktable gives the BLPS-45 a practical working surface for medium-sized dies and fixtures. Its 90 mm table thickness contributes to structural support and provides a solid foundation for production tooling. The table dimensions allow users to mount dies with sufficient space for locating devices, guide posts, material supports, and operator access provisions.
A larger table can also reduce the need for special adapters. When the die and worktable are better matched in size, the installation may require fewer auxiliary plates or extensions. This can simplify setup and improve the mechanical connection between the tooling and the machine.
The listed slide bottom size of 430 × 350 × 60 mm provides a corresponding upper mounting area. Proper matching of the slide bottom, die shank, table openings, and tooling fasteners is essential for stable operation. The listed 40 mm shank hole supports compatible punch and die arrangements, subject to confirmation of the actual tool design and mounting method.
With a maximum die height of 235 mm and a 60 mm die height adjustment range, the BLPS-45 can accommodate a useful variety of tooling heights. The adjustment function helps operators set the working position to match the selected die, material, and forming process. Correct die height adjustment is important for maintaining the intended stroke, avoiding unnecessary impact, and ensuring that the upper and lower tooling meet in the correct position.
In production environments with frequent changeovers, a practical adjustment range can reduce setup time. It enables the machine to accept different tools without requiring extensive structural modification. This is particularly valuable for job shops and manufacturers producing several component families on the same equipment.
The BLPS-45 is equipped with a 4 kW main motor in a four-pole configuration. The motor provides the drive power required to operate the press mechanism and maintain repeatable slide movement through the intended working range. Motor sizing is an important part of overall press performance because the drive must support acceleration, deceleration, repeated cycles, and the energy demands of the forming process.
The listed operating range of 50–95 strokes per minute allows the machine to be adapted to different production conditions. Higher speeds may be suitable for lighter forming tasks, repetitive blanking, or applications where material handling and die design permit rapid cycling. Lower speeds may be preferred for heavier forming, difficult materials, complex loading, inspection-sensitive work, or processes that require additional time for material positioning.
Operating speed should not be selected solely according to the maximum available value. Tool design, lubrication, material properties, strip or sheet handling, operator access, and the required quality level must all be considered. A well-matched speed setting can improve productivity while reducing unnecessary shock, heat, vibration, and tool wear.
The machine’s mechanical system is intended to provide a consistent relationship between motor rotation and slide movement. Consistency in this relationship is fundamental to repeatable forming. When the machine is properly installed, lubricated, maintained, and operated within its rated conditions, the drive system can support stable production over long working periods.
Overload protection is an essential feature for a press intended for demanding industrial production. An overload may occur when the material is harder or thicker than expected, a die is incorrectly adjusted, foreign material enters the tool, the workpiece is mispositioned, or the forming force rises above the intended level. Without a suitable protective system, excessive load can damage the frame, crank mechanism, slide, die, or other critical components.
The BLPS-45 incorporates a hydraulic overload protection device. This system is designed to respond when the applied load exceeds the permitted operating condition. By providing a controlled method of relieving excessive pressure, it helps protect the press and tooling from sudden overload-related damage.
Hydraulic protection can also support faster recovery after an abnormal event. Depending on the actual system configuration and operating procedure, the protective device may allow the machine to be returned to service more efficiently than a mechanically damaged press. The exact reset and inspection procedure must follow the equipment manual and the responsible maintenance team’s safety requirements.
Overload protection does not authorize operation beyond the rated capacity. It is a safeguard, not a substitute for correct die design, proper material selection, accurate setup, or operator training. The best results are achieved when the protection system works together with disciplined process control and regular inspection.
The BLPS-45 uses high-sensitivity dual-solenoid valve control to support reliable stop-start response. Control sensitivity is particularly important in a power press because the machine must respond predictably to operating commands, stopping requirements, and safety-related signals. An inconsistent response can affect product quality and increase risk during setup or production.
A dual-solenoid arrangement can provide controlled operation of the relevant pneumatic or hydraulic control circuit and support dependable actuation. The system is intended to improve the consistency of command execution, helping the slide start and stop in a controlled manner. Stable control is valuable during single-stroke operation, adjustment, die testing, and continuous production.
For production users, control quality affects more than convenience. Repeatable stopping and starting help maintain consistent workpiece positioning and reduce unnecessary variation between cycles. The control system can also make it easier to coordinate the press with feeding devices, material handling equipment, sensors, and other approved production accessories.
All electrical and control integration must be completed according to the applicable machine safety requirements. Emergency stopping, guarding, two-hand controls, light curtains, interlocks, and other protective devices should be specified and validated according to the intended application and local regulations.
The listed punch accuracy classification is GB/JIS Class 1. This classification indicates that the press is designed to meet a defined level of mechanical precision under appropriate test conditions. Accuracy is influenced by several factors, including frame rigidity, guide condition, slide alignment, die installation, workpiece characteristics, lubrication, foundation stability, and operating method.
For manufacturers, repeatability is often as important as one-time accuracy. A press that produces a correct part occasionally but varies significantly from cycle to cycle is difficult to use in a stable production process. The BLPS-45 is designed to provide consistent slide movement and working geometry so that properly prepared tooling can produce repeatable results.
The machine’s die height adjustment system supports setup accuracy by allowing the working relationship between the upper and lower tools to be set correctly. The operator must still verify shut height, die clearance, material location, and the required forming position. Accurate setup procedures are essential for obtaining the full benefit of the machine’s structural and control capabilities.
Periodic inspection should include the frame, table, slide, guide components, fastening systems, lubrication points, control elements, overload protection, and safety equipment. Preventive maintenance helps preserve accuracy and reduces the risk that small alignment or wear issues will become major production problems.
The BLPS-45 is suitable for a broad range of operations where its capacity, open working area, and deep reach match the process requirements. Typical applications may include blanking sheet-metal profiles, punching holes, bending brackets, forming channels, embossing reinforcement patterns, trimming formed parts, and producing components for machinery and industrial equipment.
In appliance manufacturing, the press may be used for brackets, reinforcement parts, mounting plates, and formed sheet-metal components. In agricultural equipment production, it can support the manufacture of guards, supports, linkage components, and structural pieces. In general machinery, it may be applied to covers, base plates, flanges, frames, and custom metal parts.
Automotive subcontractors may use this type of equipment for selected brackets, stamped reinforcement parts, small structural components, and tooling-related operations. The exact application depends on material grade, thickness, component size, required production volume, and die configuration. The 450 kN rating offers meaningful capacity for many medium-duty tasks while maintaining a practical machine footprint relative to larger industrial presses.
The press can also serve job shops that need flexibility. A job shop may process different materials and part sizes in the same week, making die height adjustment, table space, throat depth, and controllable speed especially valuable. The open-gap format supports custom tooling and may reduce the restrictions associated with a narrow, enclosed working zone.
For medium-duty forging or localized forming, the machine can be considered when the force curve and tooling design are appropriate. Forging applications must be evaluated carefully because impact, temperature, material volume, and die geometry can create loads different from those encountered in sheet-metal stamping.
One significant advantage of the BLPS-45 is the relationship between capacity and access. Some compact presses offer convenient installation but have limited throat depth and small tables. Others provide higher force but use a more enclosed configuration that can complicate tool access and handling. The BLPS-45 is positioned between these extremes by combining a 450 kN nominal capacity with an open-gap deep-throat working arrangement.
The enlarged worktable provides more room for tooling and workpiece support than a smaller general-purpose press. This can make die installation more convenient and reduce the need for improvised extensions. The extended reach can also improve the handling of large or irregular workpieces.
Another advantage is structural emphasis. The reinforced, heat-treated welded frame is intended to reduce elastic deformation under load. This is important because a machine with a large throat must be designed carefully to manage the increased bending moment associated with deep-reach forming. The BLPS-45 addresses this requirement through a rigid load-bearing body rather than treating throat depth as an isolated dimensional feature.
The integrated hydraulic overload protection system provides an additional layer of equipment protection. Combined with sensitive dual-solenoid control, it gives the machine a more complete protection and operating package than a basic press equipped only with a motor and mechanical transmission.
The machine also offers practical process flexibility. Its 90 mm slide stroke, 235 mm maximum die height, and 60 mm adjustment range allow it to support different tooling arrangements. This can reduce the need to dedicate separate small presses to every product variation.
Zhejiang Bolun High-Precision Machinery Co., Ltd. integrates research and development, product design, manufacturing, sales, and service. The company has approximately two decades of experience in machinery manufacturing and has developed its capabilities around high-precision forming equipment, forging machinery, casting machinery, and customized industrial machine tools.
A major strength is the company’s full-chain production approach. The manufacturing system covers basic design, core component development, precision processing, machine assembly, inspection, and customer support. This type of integration gives the supplier greater control over product consistency and makes it easier to coordinate design decisions with production requirements.
Advanced precision-processing equipment supports the manufacture of key machine components. Precision machining is important for surfaces and interfaces that influence alignment, guide movement, table flatness, slide positioning, and assembly accuracy. Careful processing of these features helps the complete press perform as an integrated system rather than as a collection of loosely matched parts.
The company also emphasizes non-standard customization. Industrial customers often require more than a standard catalog machine. They may need a specific throat arrangement, table size, tooling interface, control method, automation connection, working height, or production accessory. Bolun’s design team can provide one-stop design and manufacturing services for special specifications and functions, subject to technical review and project confirmation.
Customization capability is especially useful for deep-throat presses because the ideal configuration depends heavily on the workpiece and die. A supplier that can evaluate the entire process can help customers select a suitable capacity, working area, stroke, speed, protection system, and control arrangement rather than focusing only on nominal tonnage.
Quality control is presented as a core part of the supplier’s manufacturing philosophy. The company has established a finished-product inspection system intended to examine components, assemblies, and completed machines. A systematic inspection process helps verify whether the equipment meets the required structural, dimensional, functional, and operational expectations before shipment.
For a power press, inspection should address more than appearance. Important areas include frame geometry, table and slide alignment, die height adjustment, drive operation, control response, overload protection, lubrication, noise, vibration, and safety-related functions. Examination of these areas helps identify issues before the equipment reaches the customer’s production floor.
Consistent quality also depends on process discipline. Welding, stress relief, machining, assembly, electrical integration, and final testing must be coordinated. If any one stage is poorly controlled, it can affect the accuracy or reliability of the final press. An integrated production system allows the supplier to connect these stages and maintain traceability through the manufacturing process.
Long service life is influenced by both construction and maintenance. The company’s focus on material quality, processing accuracy, inspection, and customer service supports a machine intended for continuous industrial use. Users should nevertheless follow recommended maintenance intervals and operating limits to preserve performance.
Correct installation is essential to achieving the performance expected from the BLPS-45. The foundation must be capable of supporting the machine’s static weight and dynamic operating forces. The installation area should provide sufficient clearance for workpiece handling, die changes, maintenance access, electrical connections, lubrication, and safe operator movement.
Before commissioning, the machine should be checked for transport-related movement, loose fasteners, damaged components, contamination, and correct lubrication. The table and slide should be inspected for cleanliness and proper alignment. The electrical supply, air supply, grounding, and control connections must match the approved installation requirements.
Tooling should be installed by qualified personnel who understand the press capacity, shut height, die clearance, fastening method, and material flow. The die should be centered appropriately for the intended load. Off-center loading can create uneven stress and should be avoided unless the machine and tooling have been specifically designed for that condition.
Initial testing should begin at a controlled speed and without production material when appropriate. The operator should verify the direction of movement, stopping response, lubrication, abnormal noise, vibration, and the operation of protective devices. A first-piece trial should then be performed using approved material and a documented setup procedure.
Commissioning records should include the installed tooling, operating parameters, test results, safety checks, and any adjustments made. Such records provide useful information for future maintenance and repeat production.
Routine maintenance is necessary to preserve the accuracy and reliability of any power press. Maintenance tasks may include checking lubrication levels, inspecting moving interfaces, tightening accessible fasteners, examining electrical connections, checking pneumatic or hydraulic circuits, cleaning the working area, and verifying the response of control and safety systems.
The overload protection device should be inspected according to the manufacturer’s instructions. Any overload event should be investigated rather than ignored. The cause may be a material variation, incorrect die height, tool damage, foreign material, or an unsuitable process condition. Resetting the system without identifying the cause can allow the problem to recur.
Guide components and die interfaces should be monitored for wear. Excessive clearance can reduce precision and increase impact during operation. The table and slide should remain free from chips, scale, oil accumulation, and other contamination that could affect die seating or workpiece positioning.
Maintenance personnel should also monitor changes in noise, vibration, temperature, stopping behavior, and cycle consistency. These changes may provide early indications of mechanical wear or control-system problems. Early service intervention is generally less costly and less disruptive than repairing damage after a major failure.
Bolun’s service philosophy includes pre-sales consultation, in-sales technical support, and after-sales assistance. This service structure is important for equipment that may be integrated into a customer’s unique production process. Technical communication before purchase can help establish the correct configuration, while support after installation can assist with operation, maintenance, and future process improvements.
Although the BLPS-45 provides 450 kN of nominal capacity, press selection should begin with the complete forming process rather than force alone. The customer should identify the material grade, thickness, blank dimensions, forming type, number of operations, die size, required stroke, production rate, and expected working cycle.
Throat depth is especially important when the workpiece extends deeply into the machine. Users should consider not only the nominal throat measurement but also the actual space needed for the die, workpiece, guide components, sensors, material supports, and operator access. A practical clearance assessment prevents interference after installation.
Die height should be compared with the machine’s maximum die height and adjustment range. The selected tooling must also match the table dimensions, slide bottom, shank hole, fastening method, and working stroke. A die that technically fits the table may still be unsuitable if its load center, clearance, or shut height is incorrect.
Production speed should be selected according to the process. High-speed operation may be appropriate for simple repetitive work, while complex forming may require a slower setting. The correct speed helps protect the die, maintain material control, and support consistent quality.
Customers should also discuss automation requirements. The open-gap press may be integrated with feeders, transfer equipment, sensors, light curtains, part-removal devices, lubrication systems, or production monitoring controls. Such integration should be evaluated during the quotation and engineering stage so that interfaces are properly coordinated.
Industrial equipment should be evaluated by total operating value rather than purchase price alone. A press that supports stable cycles, quick die changes, reliable overload protection, and consistent part quality can reduce hidden costs associated with downtime, scrap, tool damage, and maintenance.
The BLPS-45’s 4 kW main motor is matched to a medium-duty press configuration. Efficient operation depends on selecting appropriate speed and avoiding unnecessary idle running. Proper lubrication and alignment also help reduce mechanical resistance and wear, supporting more efficient use of drive power.
The large worktable and deep-throat design may reduce handling steps for certain workpieces. If a component can be positioned and formed without repeated repositioning, the production cycle may become simpler and more consistent. The value of this benefit depends on the specific part and tooling arrangement, but it is an important consideration when comparing machines.
Equipment reliability also contributes to productivity. Hydraulic overload protection can help avoid severe damage after abnormal loading, while responsive control can reduce uncertainty during operation. These features do not eliminate the need for maintenance, but they support a more controlled production environment.
Power presses contain moving parts and substantial stored energy. Safe operation requires a complete system that includes suitable guarding, approved control functions, emergency stopping, operator training, lockout procedures, and regular inspections. The machine should be used only by personnel who understand the equipment and the specific production process.
The open-gap design improves access but also makes correct safeguarding especially important. Access to the die area must be controlled according to the applicable regulations and risk assessment. Protective equipment should be selected based on the tooling, workpiece, cycle mode, and automation arrangement.
Operators should never reach into the die area during an active cycle. They should use appropriate tools or approved handling equipment for workpiece placement and removal. Any unusual noise, vibration, control response, material movement, or overload event should be reported and investigated immediately.
Safety procedures should be documented and reviewed periodically. Training should cover normal operation, setup, die change, adjustment, maintenance, emergency response, and abnormal conditions. A technically advanced press can only deliver its intended benefits when operated within a disciplined safety and maintenance system.
The listed nominal capacity is 450 kN. The suitable application depends on the actual material, die, forming method, load position, and process requirements. Users should complete a forming-force evaluation before selecting the machine for a specific part.
The deep-throat design provides greater working reach behind the pressing center. It can accommodate larger or deeper workpieces and specialized tooling while reducing the need for repeated repositioning in suitable applications.
The listed BLPS-45 worktable size is 850 × 440 × 90 mm. The actual usable area may also depend on table openings, die fasteners, guide components, and any customer-specific tooling arrangements.
The listed slide stroke is 90 mm. This provides useful vertical movement for die engagement, workpiece handling, and forming operations within the machine’s intended application range.
The listed operating range is 50–95 strokes per minute. The correct production speed depends on the material, die, forming method, workpiece handling, required quality, and safety conditions.
The hydraulic overload protection device is designed to help protect the press and tooling when the applied load exceeds the permitted operating condition. It should be used as a protective measure and not as permission to exceed the machine’s rated capacity.
The listed configuration uses a 4 kW main motor with a four-pole arrangement. Final electrical details should be confirmed according to the customer’s power supply and order specification.
Yes, the open-gap deep-throat structure and practical table dimensions make the machine suitable for many custom tooling arrangements. The die must be evaluated for capacity, load center, shut height, stroke, mounting, and safety before use.
It indicates a defined precision classification for the press under applicable test conditions. Actual production accuracy also depends on foundation stability, die quality, alignment, material consistency, lubrication, maintenance, and correct setup.
Zhejiang Bolun High-Precision Machinery Co., Ltd. states that it provides non-standard design and manufacturing services for special specifications and functions. Customers should provide detailed information about the part, die, production rate, automation, and installation conditions for technical evaluation.
Customers should confirm nominal force, force position, throat depth, worktable size, slide dimensions, die height, stroke, operating speed, motor and power requirements, overload protection, control functions, safety equipment, automation interfaces, installation conditions, and service arrangements.
