2K injection molding

The 2-component injection molding process is used to manufacture composite molded parts. For this purpose, both materials are processed into a common component in a single injection molding process without the use of adhesion promoters. The bond between the two materials can be implemented chemically and/or physically by clamping, overmolding or backmolding.

With composite molded parts, time-consuming and expensive assembly and reworking can be avoided. Due to only one component, quality inspection costs can be reduced. By combining the properties of two materials, you can significantly increase the functions of the components.

The design possibilities with this process are very large and offer many possibilities. For example, in the case of a hard-soft variant, the impermeability of a component can be increased, and a damping, insulating, protective or haptic function can be integrated. In the case of a composite of two hard components, different materials can be combined in terms of color or appearance. Weight reductions can also be achieved by replacing heavy rubber-metal parts. The process is also more environmentally friendly, since less energy and material are required.
