Open-Gap Deep-Throat Power Press Manufacturers

The Bolun deep throat Series is a specialized engineering solution designed specifically for large-format sheet metal processing where standard C-frame reach is insufficient. The defining characteristic of this series is its significantly extended throat depth, providing the necessary clearance to process large workpieces far from the material edges. This makes it an indispensable asset for industries such as large-scale signage, HVAC ducting, and architectural metalwork.

Construction quality is paramount in deep-throat designs. Unlike standard presses, our series utilizes an ultra-reinforced, high-tensile steel-plate welded frame that undergoes a rigorous heat treatment process for maximum stress relief. This ensures that the frame maintains superior rigidity even with the deeper throat, effectively eliminating the risk of "angular opening" or deflection during high-tonnage impacts. Such structural integrity is vital for preserving die alignment and extending the lifespan of expensive tooling.

In terms of performance, it is equipped with a high-torque pneumatic friction clutch and a precision brake unit, allowing for rapid response and reliable single or continuous strokes. Safety is integrated at every level, featuring a dual solenoid safety valve to prevent accidental strokes and a hydraulic overload protection system that safeguards the machine from tonnage spikes.

The internal transmission relies on a forged 42CrMo alloy steel crankshaft and premium CuSn12 tin bronze bushings, ensuring long-term durability and smooth power delivery. Furthermore, the PLC-based smart control system ensures seamless "handshaking" with NC servo feeders and automation robots. With its extended reach and ultra-rigid build, the Bolun our series is the ultimate solution for manufacturers seeking to overcome the limitations of standard press geometry without compromising on precision or power.
