Injection molding is a popular manufacturing process used to create complex parts for a variety of industries. From automotive to medical and aerospace, injection molding has become an indispensable tool for producing high-quality parts in large quantities. However, one common problem that manufacturers face during plastic injection molding is weld lines. In this informative article, we will be discussing how to avoid weld lines in injection molding.

Flash in custom injection molding can be a frustrating and costly problem for manufacturers. Flash occurs when excess material flows into the space between the mold halves or between the mold and the parting line. This excess material creates a thin layer of unwanted plastic that needs to be removed, adding extra steps to the production process and potentially damaging the final product.
