Enhancing Plastic Parts With Special Manufacturing Techniques

If you are looking for ways to modify your plastic parts, you should consider the special manufacturing techniques that can help you modify them. There are a variety of techniques that can be used to modify plastic parts, each of which has its own advantages.

This article describes a few modification techniques used to manufacture custom plastic parts.

Heat Staking

Heat staking is a specialized technique used to join two plastic parts together by melting one part onto another. This process is often used when attaching components to housings or covers, and it is an effective way to ensure a strong bond between the parts.

The heat-staking process works by heating up the material until it reaches its melting point and pressing it into place on the other part. Once cooled, the parts are permanently joined together to create a reliable connection between the two parts.

Insert Molding

Insert molding involves placing an insert into a mold before injecting molten plastic around it. This technique allows for the precise placement of the insert within the resulting product, ensuring a strong connection between the components without any additional manufacturing steps.

The inserts used in this process can be made from various materials, including metals, plastics, and composites. Insert molding is often used for specialized parts where precision and accuracy are critical since the process can create complex components with tight tolerances.


Overmolding involves injecting molten plastic over an existing component or substrate to create a new part with improved properties or functionality. This technique is often used when creating rubber-like grips on handles or adding texture to a surface for better traction or grip strength.

Both are situations where adding texture after injection molding would not be feasible due to cost constraints or design limitations.

Overmolding also gives designers greater flexibility when creating complex shapes and objects with multiple materials. It allows the designers to combine different materials within one product without having to resort to using multiple molds or adhesives and fasteners during the assembly process.

These special manufacturing techniques offer many ways for you to customize your plastic parts and give them enhanced features that would otherwise not be available through traditional injection molding methods alone.

Heat staking, insert molding, and over-molding are all great options depending on the type of modification you need on your components. So make sure you consult a professional plastic parts manufacturing service before making any decisions about how to proceed.
