What is overmoulding?
Overmoulding is the process of adding an additional layer of material over an already existing piece or part. For example the steel shaft of a screwdriver is overmoulded with plastic to form the handle. The base component is placed in the injection mould tool and hot molten plastic fills the area around the inserted part, the result is an assembled product.
Overmoulding has many benefits, it reduces costs by eliminating secondary assembly operations, parts can attain a high degree of waterproofing and shock resistance, parts produced using overmoulding are tough, lightweight and chemical resistant. Various textures can be achieved, the surface can be soft touch for handling or tough for durability, products are better insulated, aesthetically pleasing and sharp edges minimised or eliminated. Many components are suitable for overmoulding including sensitive electronics and cables.

In July 2014 Inoplas developed the Moover cow slipper for a customer. The slipper is designed for dairy cows, who have a problem in one of their hoof “claws”. The slipper allows the infected “claw” to be raised off the ground and heal quickly.
