Metal-plastic composites

Contact us

We injection mould around metal parts or sensoric components, like for example magnets with thermoplastic plastics in semi or fully automatic production cells.

The constructive metal-plastic composites allow construction benefits and savings during assembly: Component groups that normally can only be assembled in several single assembly procedures, can due to moulding around one or more single metal components with different properties and functions be manufactured in a single step.


High design liberties and a higher robustness in changing temperatures

Injection moulding around a part provides high design liberties and a higher robustness in changing temperatures or shocks in contrast to component groups made of several single parts.

Injection moulding around metal parts provides an enhanced process security in contrast to assembly processes like bonding or welding in particular with sensoric components.

A selection our realized products

Automotive Construction and furniture fittings

Automotive Sensor unit: magnet and brass ring connected by plastic encapsulation
By means of plastic injection molding, several components of different materials can be positively connected to form an assembly in one operation.
Money Machines Durability test sensor
By means of metal overmoulding, components of different materials can be positively connected in order to combine the different material properties in one component.
