Benefits of Molding Inserts

Molding inserts is the process of embedding metal or plastic components into a plastic part during the molding process. The inserts are placed into the mold cavity before the plastic material is injected, and the plastic then flows around the inserts, creating a strong bond between the insert and the plastic material.

The purpose of molding inserts is to provide additional functionality or strength to the plastic part. Common applications for molded inserts include creating threaded fastening points, improving wear resistance, or adding electrical conductivity. The choice of insert material will depend on the specific requirements of the application.

Molding inserts can be designed in a variety of shapes and sizes to fit the specific requirements of the part being produced. They can be designed with features such as knurls, undercuts, or flanges to provide increased retention or improved alignment within the plastic part. 

Examples of machined molded inserts include:

Bushing inserts: These are inserts designed to act as a bearing surface between two parts. They are often used to reduce friction and wear between rotating parts.

Threaded inserts: These are inserts designed to provide a threaded fastening point within a plastic part. They can be designed with various types of threads, such as standard or metric threads.

Retaining ring inserts: These are inserts designed to hold a specific component or part in place within a plastic assembly. They can be designed with various types of retention features, such as snap-fit, press-fit, or screw-in retention methods.

Standoff inserts: These are inserts designed to create a space or distance between two parts within a plastic assembly. They can be designed with various lengths and diameters to suit the specific requirements of the application.

Knurled inserts: These are inserts designed with a knurled surface to improve the grip and retention of the insert within the plastic part.

Flanged inserts: These are inserts designed with a flange to provide increased retention and stability within the plastic part. 

Heat-set inserts: These are inserts designed to be heat-staked into a plastic part. The heat from the staking process melts the surrounding plastic material, creating a strong bond between the insert and the plastic part.

Self-tapping inserts: These are inserts designed to tap their own threads into a plastic part during installation, eliminating the need for pre-tapped holes.

Molded-in inserts: These are inserts that are molded directly into the plastic part during the molding process. They provide a strong and permanent attachment point, as the plastic material flows around the insert during molding.

Key-locking inserts: These are inserts designed with a locking mechanism to prevent the insert from rotating or backing out of the plastic part.

Compression limiters: These are inserts designed to limit the compression of a plastic part during assembly, preventing damage to the part and ensuring proper alignment.

Serrated inserts: These are inserts designed with a serrated surface to improve the retention and grip of the insert within the plastic part.

One of the advantages of molding inserts is that they provide a more secure and permanent attachment than other types of fasteners. They also reduce the need for additional assembly steps, as the inserts are embedded directly into the plastic part.
