Plastic parts overflow the edge
The treatment of overflow should focus on the improvement of mould.And in the forming condition, can begin in reducing the fluidity aspect.Specifically, the following methods can be adopted:
1) reduce injection pressure.
2) reduce the resin temperature.
4) select high viscosity grade materials.
5) lower mold temperature.
6) the mold surface caused by grinding overflow.
7) use hard mould steel.
8) improve the locking force.
9) adjust the binding surface and other parts of the accurate mold.
10) add die support column to increase rigidity.
Ll) determine the size of different exhaust grooves according to different materials.
