1. Advanced two way cartridge valve system ensures high reliability and much less hydraulic shock direction change;
2. Main hydraulic cylinder is made of alloy cast steel and it’s inner surface is finely grinded for life under high pressure;
3. Four columns are made of alloy steel with high tensile resistance and finely grinded and electro-plated with hard chrome;
4. Key hydraulic and electric units adopted are famous brands from Germany USA and Japan;
5. Fast approaching speed of movable working table creates higher production efficiency;
6. A hydraulic ejector is installed on movable working table for knocking out workpiece after drawing.
1. Deep drawing and forming of tableware , kitchenware , metal cover of electric motor , household appliances and lighting ware etc;
2. Main hydraulic cylinder is made of alloy cast steel and it’s inner surface is finely grinded for prolonging working life under high pressure.
