Read More1, mold opening, mold locking, ejector, and other actions using high-precision screw nut, transmission accuracy of 0.01mm.
2, linear guide rail, the traditional reciprocating sliding guidance into rolling guidance, improve positioning accuracy, reduce th
Vertical column-free mold locking, horizontal injection, mold open on three sides, more convenient and safer operation.
High injection pressure, torque type hydraulic motor control, high spiral torque, high pre-molding volume, system pressure controlled
Cause
1.Injection pressure or barrel temperature
2.Too much feed material
3.Too long advance time of the pump column
4.Unbalance of the feeding port in multiple writing
5.There is a depressed part in the mold
Injection molding is an engineering process that involves the transformation of plastics into useful and functional products. The important process conditions of injection molding are the temperature, pressure and corresponding work of each action that af
