Valve gate hot runner injection mold has many advantages

Valve gate hot runner injection mold has many advantages. When the resin melt viscosity is low, avoid drooling phenomenon; higher temperature can be reduced when drawing phenomenon. Spool into the front gate and cavity flush products basically without leaving traces of the gate. Valve gate can be opened and closed as required to  Instrument valve manifolds  the feeding time, broaden the range of processing, reduce internal stress of plastic parts. Reduce stress cracking and warpage, increase the dimensional stability of plastic parts. Further, gate valve before opening the valve can be subjected to the pre-injection machine barrel pressure,  Valve manifolds  of the plastic produced, the moment when the gate is open, the rapid expansion of the volume of the pre-compression, greatly shorten the filling time shorten the cycle. Because the valve gate has so many advantages, it is widely adopted.
