What is Overmolding? ​

Overmolding is a manufacturing process that creates a single component by partially or completely encasing one material in another. The base material can be molded plastic, CNC-machined metal, or pre-made goods such as screws and threaded inserts. The overmolding material, typically a type of rubber or plastic mixed with colorants and blowing agents, is heated until it melts and then poured into molds in liquid form. This technique allows for the production of complex shapes and multi-material components. Overmolding not only improves product comfort and performance but also effectively satisfies material, performance, and exact tolerance requirements without increasing production costs or duration.

It offers a cost-effective method with faster turnaround times by eliminating the need for extra assembly steps, thus enabling products to reach the market sooner. This efficiency makes overmolding an excellent choice for reducing overall production costs and accelerating time to market.

Advantages of Overmolding ​

Enhances Functionality and Comfort Overmolding improves function and comfort by creating soft-touch handles, as seen in surgical instruments. Aesthetic Customization It allows for molding multiple colors onto a product, enhancing its aesthetic appeal or branding. Reduces Manufacturing Costs By eliminating the need for secondary assembly steps, overmolding helps reduce overall production costs. Increases Strength and Durability Overmolding can enhance the strength, durability, and aesthetics of plastic parts, while also adding new functionalities like grippy surfaces or watertight seals.

Types of Overmolding ​

Different types of overmolding cater to various needs, making it a flexible option for enhancing part performance and design. The four primary types of overmolding include:

1. Plastic-over-Plastic: Adds an additional layer for increased strength or visual appeal.

2. Rubber-over-Plastic: Uses rubber to improve grip or create a watertight seal.

3. Plastic-over-Metal: Coats a metal core with plastic to enhance durability or aesthetics.

4. Rubber-over-Metal: Applies rubber to metal to improve durability or grip. This range of options enables designers and engineers to choose the most suitable method based on their project's specific requirements.
