What is Overmolding?

Overmolding is a process that uses plastic to fuse two or more different materials together. It is an important part of modern manufacturing. Whether it is a plastic product or a metal component, overmolding helps manufacturers combine materials to produce a more cohesive product.

What is Insert Molding？

Insert molding is a common plastic manufacturing process that combines two different materials into one final product. It is advantageous in many ways, reducing assembly and labor costs while providing the strength and durability needed for various products.

Overmolding Material Selection

When deciding on the right overmolding material, it is important to consider the application of the part. While a wide range of plastics are available, some are more suitable for specific applications than others. For instance, HDPE is well-suited for large parts that need to be durable and weather-resistant. ABS, on the other hand, is a manufacturable plastic, common in electronics, which has several advantages. It has a low melting point, is moldable, and has good tensile strength. It also has low heat conductivity, making it ideal for electrical insulation.

While the molds themselves are similar, part quantities, lifetime maintenance, quality documentation, and pricing vary depending on which service option is chosen. The right one depends on your project needs.

How Does Plastic Injection Molding Work?

Plastic injection molding is a process in which plastic pellets are formed and injected into molds to form the desired shape. The plastic melts in a chamber and reaches a specified temperature, so the injection time has to be calculated correctly. Once the desired shape is achieved, the plastic pellets are cooled, and the mold is opened. An ejection bar is then used to force the solid plastic part out of the open cavity.

What is insert molding ?

What is the difference between overmolding and insert molding？

Insert molding and overmolding are two different processes that are used to create similar but distinct products. In insert molding, a thermoplastic is applied to an elastomer or rubber substrate and then suspended within a mold. The process is useful for creating intricate shapes and complicated dimensions. Often, the substrate is an additional material that is necessary to complete the design. This can include a wire, a computerized part, or other materials.
