Closed-Type Double-Point Press Manufacturers
Bolun’s heavy-duty series, featuring the BLPC and BLPE models, represents the ultimate solution for high-precision, high-tonnage stamping environments. Engineered for durability and digital integration, these machines are designed to excel where standard equipment fails.
BLPC Series: High-Performance Double-Point Precision Press
The BLPC series is specifically engineered for wide-table applications and complex multi-station tooling.
Superior Anti-Eccentric Loading: Utilizing a dual-point drive mechanism, the BLPC series offers exceptional resistance to eccentric (off-center) loads. This ensures the slide remains perfectly horizontal even when using wide or unbalanced progressive dies, significantly reducing tool wear and ensuring consistent part quality across the entire bolster area.
Large-Scale Versatility: The expanded bed area is optimized for large automotive panels and appliance housings, allowing for more complex part geometries and integrated stamping processes in a single setup.
Vibration Damping: Its robust double-point architecture naturally dampens harmonic vibrations, protecting delicate die components and ensuring a stable, low-noise production environment.
BLPE Series: Ultra-Rigid Closed-Type (H-Frame) Precision Press
The BLPE series is the "Gold Standard" for heavy-duty blanking and precision forming where zero deflection is mandatory.
H-Frame "Zero-Deflection" Design: The symmetrical, closed-type H-frame structure virtually eliminates the "angular opening" common in open-back presses. This ensures perfect vertical alignment between the punch and die, which is critical when processing high-strength alloys or thick materials exceeding 3.2mm.
Micron-Level Repeatability: The ultra-rigid foundation provides the stability required for high-speed automated lines, maintaining extreme precision even under maximum tonnage.
Long-Term Reliability: Designed for heavy blanking and deep drawing, the BLPE series handles massive impact loads with ease, making it the preferred choice for 3-shift high-frequency production.
Engineering Excellence & Automation
Both series are equipped with forged 42CrMo alloy steel crankshafts and CuSn12 tin bronze bushings for maximum service life. Integrated with PLC-based smart controls, they offer seamless "Handshaking" with NC servo feeders and robotic systems, providing a complete "Smart Factory" solution for modern manufacturers.
