This equipment is specialized equipment designed for expanding and contracting the liquid storage cylinder of the automobile

shock absorber. This equipment changes the traditional single-head expansion or shrinkage mode and adopts upper and lower oil

cylinders to work with the processing mold, which can process both single-head expansion and shrinkage products at once, improve the accuracy of the workpiece, reduce the production cycle, and reduce production costs. This equipment is powered by hydraulic pressure and utilizes a microcomputer to control various components to carryout required actions. The equipment is user-friendly.
