Four Pillars Hydraulic Press 4 Columns Deep Drawing Hydraulic Press Advantage
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.
Four Pillars Hydraulic Press 4 Columns Deep Drawing Hydraulic Press Application
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.
