The YS51-Vulcanizing Hydraulic press is used for heat exchanger gaskets production. The structure of the machine is frame structure, with the cylinder on bottom. The machine has independent hydraulic system and PLC electric control system. It has centralized button-control system with manual and semi-auto work modes for selection. The working pressure and the work feed speed can be adjusted. The action of cylinder quick up, work feed, increasing pressure and return etc. can be done by this machine. The working performance is stable. It can be connected with heating system for gasket vulcanize production.
