Multi-component injection molding

Functional integrations through directly connected moulded parts

At several locations, we produce moulded parts from two or more materials for our customers in a wide range of industries. Without using any bonding agents, components with hard and soft components or other different properties are produced by clamping, overmoulding or backmoulding. We convert the compound chemically and/or physically.

The resulting components combine the properties of even the most diverse materials. They reduce or avoid assembly and rework processes and setup times, and if components are reduced, expenses for quality inspections are reduced as well. At the same time, we integrate functions, combine product properties and reduce material and component weights.

Hybrid components are also produced in the OKE Group as metal-plastic composites or as fibre composite components, which we present under the navigation item Hybrid Components at OKE.

Benefits of multi-component parts

Integration of several properties/functions into a single component by using plastics with different technical properties (such as hard and soft plastics, different colour combinations, etc.).
Production of ready-to-install series parts with only one injection mould.
Lower expenses for quality inspections through elimination of components.
Less material is used when components are reduced or, for example, when soft components are only selectively reinforced.
In most cases, no further processing is necessary as (manual) inlays and component assembly are not required.

Time saving through shortened cycle times and a consistent manufacturing process.
Creation of clear clean edges as the melts come together in the same tool in an optimised flow and cool completely together – they adhere to each other but do not run between each other.
Burrs on the second component are virtually impossible since – especially when compared with overmoulding – the polymer is still warm and has not yet shrunk.
Clean surfaces with good molecular adhesion.

Hybrid components

We also combine different material properties through fiber- or metal-reinforced components. Find out more!
