Overmolding

Overmoulding is a specialized injection moulding process that combines different materials to create composite parts with multiple properties. This process is integral in the production of complex components used in various industries.

Key Features of Overmoulding:


  • Material Fusion: Begins with moulding a base part, followed by additional layers that are moulded around it.

  • Material Variety: Multiple plastic resins can be utilised to ensure material compatibility and desired final properties.

  • Aesthetic and Functional Design: Allows for the addition of colour contrasts and the combination of rigid and flexible elements in a single part.



Applications of Overmoulding:


  • Wide Industry Use: Common in medical, automotive, and military sectors due to its versatility.

  • Product Examples: Notably used in consumer products like toothbrushes, which may have a hard plastic body with a soft, rubberised grip.



Distinguishing Overmoulding from Multi-Injection moulding:


  • Sequential Process: The substrate part is moulded first, then a second layer is applied in a separate operation.

  • Bi-Material Production: This technique enables the creation of components with two distinct materials using a standard injection moulding machine.

    Overmoulding continues to be a key manufacturing technique due to its ability to enhance product functionality and appeal while ensuring durability and comfort in end-use applications.
