Performance characteristics
★ computer optimized structure design, the four-column structure is simple, economical and practical, and the frame structure has good rigidity, high precision and strong ability to resist bias load.
★ hydraulic control adopts plug-in basic system, which has reliable operation, long service life and small hydraulic impact, which reduces continuous pipeline and leakage point.
★ controlled by imported PLc has compact structure, sensitive, reliable and flexible work, reliable operation and convenient maintenance.
★ through the operation panel selection can not only achieve fixed-range, fixed-pressure two forming process, but also can achieve pad, padless, out of three process work cycle.

Areas of application
Suitable for drawing, bending, forming, blanking, flanging and other stamping processes, especially in the following fields:
★ automotive parts: body coverings, brake pads, fuel tanks, chassis, axle housing, bumper;
★ household appliances: washing machine parts, electric cooker parts: television parts, refrigerator parts;
★ kitchen utensils: sink, kettle, stainless steel utensils, other various containers;
★ others: tractors, motorcycles, aerospace, aviation.
