Types of Moulding Inserts

Moulding inserts are an essential component in the plastic injection moulding process, allowing for the creation of intricate and detailed plastic parts. There are several types of moulding inserts that serve different purposes and are used in various applications. One common type of moulding insert is the core insert, which is used to create internal features in a plastic part. Core inserts are typically made of hardened steel and are used to form holes, threads, or other complex geometries within the molded part.

Another type of moulding insert is the cavity insert, which is used to create the external features of a plastic part. Cavity inserts are also commonly made of hardened steel and are used to create the outer shape and surface finish of the molded part. These inserts are essential for producing parts with precise dimensions and details.

In addition to core and cavity inserts, there are also ejector pins, which are used to eject the molded part from the mould after it has been formed. Ejector pins are typically made of hardened steel or other durable materials and are designed to withstand the high pressures and temperatures of the injection moulding process. Ejector pins are crucial for ensuring that the molded part is released smoothly and without any damage.

Overall, moulding inserts play a vital role in the plastic injection moulding process, allowing for the creation of complex and detailed plastic parts. By using different types of inserts, manufacturers can produce parts with precise dimensions, features, and surface finishes. Understanding the different types of moulding inserts and their functions is essential for achieving high-quality and consistent results in plastic injection moulding.
