Injections molding method:
1. The mildew temp should not be way too high. 2. The barrel temperature ought not to be excessive. 3. The injections pressure might be increased properly. 4. Appropriately raise the injection pace. plastic injection moulding ，5. The holding time needs to be set up much longer. 6. Appropriately raise the chilling time. 7. Handle the chilling velocity from the mildew.
Materials:
Select resources with uniform debris, so the debris are heated consistently, the temperature is consistent almost everywhere, as well as the cooling down rate is standard. It can be needed to pick the suitable molecular bodyweight and dissolve directory, so the process situations are simple to handle, the filling movement is stable, and the shrinkage rates are decreased.
In the mold side:
In accordance with the fungus shrinkage level, the fungus cavity dimension threshold ought to be reasonably designed, and the fungus material together with the small development coefficient ought to be chosen.
1. The entrance go across-sectional location is appropriately increased to help reduce shrinkage.
2. Reduce the interior flow route minimizing the movement span percentage, which is useful to providing.
