     1, how to determine whether the pressure relief injection molding machine?

     
         The use of mold transfer to the mold to tighten the head, that is, the machine can keep the high-pressure mode-locked but not on the lock. The pressure of the high-pressure lock to the maximum flow, manually press the lock mode key, has been kept according to do not release, observe the pressure gauge, whether the pointer can be maintained, if the pointer will not slow down on the pump does not pressure , If the pointer slowly down shows that the pump has a pressure relief phenomenon
     
         2, how to determine the tightness of the screw system (only reverse ring / screw sealing)
     
         In the production of melt is completed, and then extended for a while to determine the product and the flow channel system is completely cooled, change the semi-automatic manual, start shot, and observe the screw position, if the screw slowly move forward, that screw system leakage rubber, otherwise No leakage of plastic.
