Feature: 1.Three beam and four pillar type construction, optimized design by computers, is easy, economic and practical. Hydraulic control system adopts cartridge valve intergrated system with reliable operation, long service life, small hydraulic shock, which reduces connection lines and leaking points. 2.Independent electrical control system, which is liable, intuitive and easy to maintenance. 3.Use intergrated pushbuttons, with two operating modes, adjustment(inching) and single pass(semi-auto). 4. Through the operation panel selection, which can achieve two forming process( fixed stroke and fixed pressure). It has pressure maintaining and time delay functions. 5. Working pressure and stroke can be adjustable in defined limits according to the arts.
