Problems solved by technology

[0002] In the production process of auto parts, due to the overall large structure of the molded product, the molding cavity in some parts of the mold is small. It is difficult to completely fill the entire injection cavity with traditional pressure injection molding. At the same time, this position uses solid Injection molding is prone to water marks due to shrinkage, resulting in poor product appearance quality, thereby reducing the overall pass rate of the product and seriously affecting the economic benefits of the company.
