What should I do if impurities and black spots appear during the custom injection molding process of electric toothbrushes? Shanghai Mulan Injection Molding Factory stated that black spots are black spots that appear on the surface of injection molded parts after injection molding. Such spots will affect the appearance quality of the product, affect the delivery of the product, and cause waste of raw materials. Black spots are a common defect in the injection molding process. As a common electric toothbrush in small household appliances, how to avoid magazine black spots during custom processing?
As a Japanese brand serving Japanese brands for more than 10 years, it focuses on the customized business of small household appliances, household beauty instruments, and maternal and child products. Shanghai Mulan Injection Molding Factory stated that the problem of black spots needs to be reviewed from the flow channel aggregate, ingredients, feeding, environment and production and processing links. In general, there are mainly the following reasons:
1. The decomposed material of the raw material is attached to the inner wall of the barrel, and the barrel needs to be cleaned thoroughly, or the temperature of the melt is lowered, and the amount of residual material is reduced;
2. There are foreign objects mixed in the raw materials, or the drying barrel is not cleaned, it is necessary to check whether there are black spots in the raw materials, or clean the drying barrel thoroughly;
3. The heat-sensitive plastic gate is too small and the injection speed is too fast: increase the gate size and reduce the injection speed;
4. The dust in the air enters the drying barrel: the air inlet of the drying barrel is equipped with a dust cover.
