The aesthetics and comfort of injection molding products. So, what should I do if the front of the electric toothbrush appears during injection molding?
Shanghai Mulan Injection Molding Factory stated that there are many situations where electric toothbrushes are molded by injection molding, which requires specific analysis of specific issues.
1. If it is caused by insufficient strength of the injection mold, you can increase the strength of the injection mold, and add a brace between the movable template and the ejector plate;
2. If it is caused by the unreasonable design of the injection molding product, it is recommended to reduce the shrinkage of the product by reducing the shrinkage rate of the product and reducing the injection pressure, which can change the situation of the front;
3. Increase the injection point, especially the shrinkage position of the injection molded product, increase the injection point, and reduce the injection flow channel and injection pressure to alleviate the generation of the front.
