Overmolding Injection Molding

Overmolding mold is made of overmolding injection molding process which is a special injection molding process that can combine various materials into a single part. Through mechanical and/or chemical bonding of two plastic materials, the overmolding injection molding process can be used to help product designers achieve additional functions or aesthetics that are not practical.

Here at Packson, we have over 10 years experience for making contract overmolding product and we've been working with BD, Lear for creating overmolded part which is used for medical and automotive overmolded parts.

Characteristics of Overmolding Mold

With the rapid development of mold making, overmolding mold becomes very popular for molding parts with better practicality. The followings are the characteristics of overmolding mold/overmolding injection molding:

Combine two materials for reaching additional function

Cheaper than molding separate two different materials

Better product properties like waterproof, shockproof, and windtight

Various textures feel

Advantages of Contract Overmolding Injection Mold

Overmolding insert molding may cause additional cost of operating and machine costs. However it still brings us many advantages:

Improve Part Performance.

Overmolding injection molding has a strict requirement and ensures the mating of parts.

Decrease the part cost.

The overmolding remove the processing of secondary operation so it will help to reduce some labor cost also overall cost.

Enhance Design Flexibility.

It is feasible to design and manufacture complex assembly of multi-material parts by overmolding medical grade plastics injection molding.

Application of Contract Overmolding Mold

We use overmolding molding over molding for a variety of industries.Here are some examples of application for overmolding injection molding:

Consumer part

Look around you house. You can find many overmolding mold products from toothbursh to children's game parts.

Automotive Part

Electronic sensors and other automobile parts made of metal and plastic or rubber materials are usually manufactured by overmolding injection molding.

Medical Part

Defibrillators, medical cables and wires are usually made by overmolding injection molding and encapsulated in plastic for protecting important parts.
