レン成形用圧縮装置。 A small-diameter moving cylinder is formed within the piston of a large-diameter compression cylinder, and an insertion tube is fixed inside the compression cylinder and inserted into the moving cylinder while maintaining a gap, and the bottom of the compression cylinder Connect the piping connecting the two sides via a check valve to one port of a control valve with a solenoid that switches the oil supplied from the hydraulic source, and connect the rod side and bottom side of the compression cylinder to the other port. The pipes are connected through a check valve, and the rod of the piston is connected to a compression plate for molding ultra-high molecular weight polyethylene, so that the structure can automatically switch from a high-speed movement process to a high-pressure compression process. A compression device for molding ultra-high molecular weight polyethylene.
