In this type of overmoulding, a metal part is inserted into the mould and a plastic polymer is injection-moulded around the metal part. This may entail some of the metal protruding externally beyond the plastic or the metal may be encased but with key parts exposed.
We use this type of overmoulding with a range of different materials, often with a substrate made from ABS and an overmould with a TPE or acrylic. The skill here is to secure full bonding between the materials to ensure longevity and robustness. This is achieved through a combination of temperature, the speed and pressure of the injection process, and the cooling parameters.
Not all material combinations can be successfully bonded, but our team have built expertise over many years.
In addition to standard plastic-on-plastic overmoulding, we also offer twin shot (2K) moulding. This process involves injecting two different polymer materials in sequence within the same mould tool and machine cycle, enabling enhanced functionality, improved ergonomics, integrated sealing features or distinct aesthetic finishes.
The most common reasons we are asked to overmould plastic on plastic are:
Our intuitive overmoulding process takes care of everything on your behalf.
We work closely with you to understand your requirements and integrate overmoulding into your product design from the outset, ensuring your product is tailor-made for your needs.
Utilising our moulding experts, and our advanced tooling and injection moulding technology, we produce accurate, high-quality overmoulded components to the highest standards, with consistent results.
