Introduction

The four column hydraulic press is able to stamp, bend, flange or draw malleable materials, and press powders or metallic materials. The machine press has more than 20 models for you to choose from.

Features of Four Column Press
1. The four column press is provided with a relay control system and a PLC control system. Its operating modes include adjusting, manual and semi-automatic mode. It supports pressure setting or stroke setting.
2. The four column press delays for maintaining pressure and automatically makes a return stroke after pressing in the pressure setting mode.
3. In the middle of workbench, there is an ejector that can push out workpieces and help the hydraulic cushion to process reverse-drawing workpieces. Its working pressure and stroke may be adjusted within a limited scope according to actual demands.
