Over Molding

Eigen is the recognised leader in the field of overmolding. With our vast experience in custom plastic overmolding, mold designing and building, and customer focused design solutions; Eigen has established a name for itself worldwide. We have partnered with many customers to manufacture overmolded plastic products that have reduced labour and cut assembly costs, at the same time enhancing the quality, credibility and integrity of the final product.

Overmolding is the process of adding an additional layer of material over an underlying material. It is a procedure that melds the high strength and stiffness of continuous fibers with freedom of design and flexibility. This technology overcomes the limitation of stamp forming by combining the two processes. Moreover, the process can be easily automated and is well suited for high volume production.

Eigen offers the following Overmolding techniques:

• Plastic Over Plastic– Firstly, a rigid plastic under layer is molded. Then another rigid plastic layer is molded onto or around the first layer. The plastics may differ, but ought to be complementary.
• Rubber Over Plastic– Firstly, a rigid plastic under layer is molded. Then, rubber is molded onto or around the under layer. This is done so that there is a good grip.
• Plastic Over Metal- Firstly, a metal is stamped, tooled or formed. Then, it is injected into an injection molding tool and the plastic is molded onto or around the metal. This is done in order to capture metal components in a plastic part.

Plastic Overmolding

Eigen provides solutions for a wide range of components and industries, such as:

• Medical devices and instruments
• Parts with soft grip handles
• Knobs for appliances, controls and assemblies
• Encapsulated electronic devices and electrical components
• Window reveal moldings

Meticulously engineered custom overmolded plastic parts and components can remove the need for a variety of secondary operations such as welding, bonding, gasketing and assembly, leading to time and cost savings. Eigen also employs robotic automation for quick and precise insert placement.

Eigen has continued to set the standard in overmolding.  Working with Eigen gives you the benefit of a world class engineering team, located across geographies that can ensure quick delivery of the highest quality from concept to delivery and after sales service.
