Overmoulding 2K&3K Components

Overmoulding 2K&3K Components



We specialize in custom plastic overmoulding, a process of moulding a thermoplastic over another thermoplastic to form a single part.

In the plastic overmoulding process, two materials are bonded together during injection moulding to create plastic parts and components with unique aesthetics or ergonomics, such as handles and knobs.

You can overmould a variety of thermoplastic materials, such as urethanes, thermoplastic elastomers (TPE), nylon, and polycarbonate.

In addition to strengthening, protecting, and improving a part or end product, custom plastic overmoulding reduces labour and material costs.





Plastic overmoulding offers numerous advantages, including:

  • Reduction of secondary operations, assembly costs, and labor costs (Molded as one assembly)
  • Enhances component reliability by eliminating the bonding step in the manufacturing process

Structure and strength of the part have been improved

In addition to ensuring alignment and preventing loosening, plastic overmoulded components can provide greater vibration and shock resistance

Multi-material components and enhanced design flexibility (Custom plastic overmolding enables parts to be molded from multiple thermoplastic materials).



Competitive Benefits

Proper mold design and construction and material selection are important in custom plastic overmolding to maintain part tolerances and tooling reliability. We often employ robotic automation in the plastic overmolding process for fast and precise placement of inserts.

Whether reengineering existing products or developing new products, carefully engineered custom overmolded plastic parts and components can eliminate the need for a variety of secondary operations such as sonic welding, bonding, gasketing and assembly, saving time and money.
