Product Applications

Reverse drawing hydraulic press is specially designed for stainless steel product, such as kitch ware like water sink, pot, pan etc. It is particularly applicable for stainless steel sheet metal drawing, stainless steel plate stretching and high pressure forming process.

Characteristics

• Instead of four-column fast drawing hydraulic press, reverse drawing hydraulic press is specially designed for ball or difficult one-time stretch molding productions and it can improve the efficiency by 40%, saving electric power 30% to 40%.

• Reverse drawing hydraulic press has enormous advantages,including high efficiency, energy saving and powerful blank holder force.

• Main cylinder can maintain pressure and lower cylinder has sub-stretching function.

• Electrodeless voltage transformation is used for main cylinder blank pressing, the lower cylinder uses the position sensor, and the adjustment of depth is accurately and conveniently.
