Multi-component injection molding - a sensible addition from both worlds

When it comes to manufacturing components that need to be both strong and flexible, separate parts made of plastic and elastomer are often used. But why not combine both materials in a single component? This is exactly what multi-component injection molding makes possible. With this technology, the positive properties of plastic and elastomer can be combined, which opens up a wide range of possible applications.

Molded elastomer parts and plastic components are often used together if the properties of a single material are not sufficient. For example, the hard component can absorb mechanical loads, while the soft component acts as a seal, protection, or cushioning. Multi-component injection molding makes it possible to combine both properties in one component and thus to create a meaningful complement from both worlds.

Through the use of multi-component injection molding, investments and effort in production and quality assurance can be reduced by implementing a skilful design as early as the development phase. This avoids subsequent processing steps such as welding, gluing or vulcanizing, thus saving time and money. This not only leads to more efficient production, but also to a higher quality of the manufactured parts.

Multi-component injection molding can be used to produce custom bezel-type silicone keyboards. A front panel with integrated mounting sockets is overmoulded with silicone to create an optimal bond between the individual components and to create a completely closed surface. This keyboard is therefore protected against the ingress of water and dust, which makes it ideal for hygiene-sensitive areas. In addition, the closed surface enables quick, easy and thorough cleaning.

After the injection molding process, the individual keys can be painted, printed or lasered in a further processing step. In addition, special surface coatings with PU or epoxy coating are possible. With all these options, it is possible to develop a keyboard that meets the customer's specific requirements and is optimally suited for applications in hygiene-sensitive areas.
