The perfect form for home appliances

with 100 millions of assembled home appliance components, more than twenty years of experience and a large number of international production sites.

On-spec plastic components and systems for home appliances.


Strong in large dimensions and an efficient implementation of the quality you require. 

An increased trend towards more efficient machines has also increased the requirements regarding component quality and dimensioning. As a global full service provider we produce water-bearing, decorative and technical plastic components as well as modules for washing machines, dishwashers, tumble dryers, stoves and refrigerators, not only in our plants but also shop-in-shop with our customers. Since the production of the first tub for BSH Hausgeräte GmbH in 1996, we have continuously expanded our know-how and capacities in the white goods sector. We have turned into one of the market leaders in this fast-growing business unit.

Automatable plastic technologies for optimum efficiency and availability.

With scalable injection molding processes, such as physical foaming (Cellmould®/MuCell®), multi-component- and hybrid injection molding, GID or the stack mold technology, we make us of all technologies worldwide to take your idea to series production quickly and efficiently. Interlinked and automatable assemblies, refinements and density tests round off our full service specter.  

  • Component development and simulation 
  • Tool design and construction, also of large-dimensioned components
  • Series production and refinement 
  • Series assembly and testing
