Closed-Type Single-Point Wide-Door Power Press Manufacturers

The Bolun Closed-Type Single-Point Wide-Door Power Press is engineered for manufacturers who demand absolute structural integrity and high-precision performance under heavy-duty loads. Combining the legendary stability of an H-frame design with the operational flexibility of wide side-access windows, this press is the ultimate choice for automotive, appliance, and heavy industrial stamping.

Ultra-Rigid H-Frame Construction

The defining feature of this series is its closed-type H-frame structure. Unlike standard C-frame presses, the symmetrical box-type design virtually eliminates "angular deflection" or frame opening during high-tonnage impacts. This ensures that the punch and die remain in perfect vertical alignment, significantly extending tooling life and maintaining micron-level part consistency, even when processing high-strength alloys or thick materials exceeding 3.2mm.

Wide-Door Design for Automation Integration

The "Wide-Door" or wide-side-opening configuration provides a strategic advantage for modern production lines. These spacious side windows allow for effortless integration of automated transfer systems, robotic arms, and complex coil-feeding mechanisms. Furthermore, the wide-door design simplifies tool maintenance and die-change operations, drastically reducing downtime in high-frequency production environments.

High-Torque Transmission and Core Excellence

Inside the machine, Bolun’s commitment to quality is evident. The press features a forged 42CrMo alloy steel crankshaft and premium CuSn12 tin bronze bushings, providing a transmission system that is both smooth and incredibly durable. Equipped with a high-performance pneumatic friction clutch and a precision brake unit, the press offers rapid response and reliable single or continuous strokes.

Intelligence and Safety

Safety and precision are managed by a sophisticated PLC-based control system with a high-resolution HMI. Every unit includes a hydraulic overload protector to safeguard the machine from tonnage spikes and a dual solenoid safety valve to prevent accidental strokes. Whether you are performing deep drawing, heavy blanking, or multi-stage stamping, the Bolun Wide-Door Press provides the rigid foundation and digital intelligence required for the next generation of smart manufacturing.
