core and cavity in injection molding

Precision Electronic Consumer Moulds introduction

In injection molding, the core and cavity are two crucial components used to create a molded part. The core is a solid or hollow piece that forms the internal features of the part, while the cavity forms the external shape. Together, they create the desired shape of the final product.

During the injection molding process, molten plastic is injected into the cavity through a small opening called a gate. The plastic fills the cavity and the core creates any internal features of the part, such as holes, threads, or channels. Once the plastic has cooled and solidified, the mold is opened and the part is ejected.

The design of the core and cavity is critical to the success of the injection molding process. They must be precisely machined and aligned to ensure that the final part is accurate and free of defects. Factors like material type, wall thickness, and part geometry can all impact the design of the core and cavity.
