Guangduan JH31 – Closed-Frame Mechanical Press
🧱 Rigid box frame · 🛞 Wet clutch/brake · 🎯 Four-side slide guiding
The JH31 is Guangduan’s single-point closed-frame press built on a one-piece box construction for high stiffness and low deflection. An eccentric crankshaft improves off-center capacity while the wet clutch/brake ensures smooth, cool, long-life engagement. A four-side gibbed slide sustains accuracy over time. Electric die height with digital readout speeds setup; hydraulic overload protection safeguards press and dies. PLC + pneumatic control supports continuous, single and inch modes with easy integration to feeders/straighteners/decoilers and safety light curtains.
