The injection molding process of connector refers to the connector box base shell made by rapid cooling and forming after injecting the molten plastic into the metal fetal film. Injection molding is an important link in connector production. It is easy to lose production if you are careless. Common problems in the injection molding process include:
first, warpage and deformation are caused by residual force ejection caused by uneven shrinkage or injection pressure.
2、 When forming, the joint surface of the die cannot be closed, resulting in film. It is called hairiness or burr phenomenon.
3、 During demoulding, the demoulding is not smooth due to top penetration or unbalanced ejection.
4、 The glue closing line is obvious when multi-point glue feeding.
5、 When the melt glue is taken into the mold cavity, the filling of the product is insufficient because a certain area of the product cannot be completely filled.
6、 Plastic is mixed with other foreign matters, resulting in product color mixing. Foreign matters include oil, different plastics, metals, ashes, etc. Connector manufacturer txga is a professional connector manufacturer with quality control, full delivery inspection, sufficient inventory and complete models.
