Combining colors and materials in an efficient way.

High-quality multi-color design, lower-cost parts, complex molded parts consisting of two or more components – multi-component technology has developed rapidly in recent years: More and more new process variants, plastics and material combinations are being added for  newer applications in the automotive, medical and communications technology, electronics, packaging and sporting goods industries.


In addition, multi-component technology offers solutions for sustainability and helps to increase the proportion of recycled materials in components without having to compromise on surface quality.

  • High quality of parts
  • Functional integration
  • Efficient
  • Design
  • Low space requirement
  • User-friendly

Latest injection moulding technologies.

  • Bi-injection – simultaneous or delayed injection of two components into the same cavity
  • Core-Back process – injection of two components into one cavity in sequence; cavity for second component is released by pulling a gate valve
  • Transfer process – preform is transferred manually or by robot to the second cavity or second machine
  • Turning process – transfer by axial or vertical turning with turning function in the machine or in the mould

Tailored to your applications.

Behind the term "multi-component technology" is a multitude of different tool and machine technology processes. What they have in common is that several injection units inject different materials into or onto each other to form a moulded part. When the components are injected into one another, they combine to form either "homogeneous" (e.g. rear lamp) or "heterogeneous" moulded parts (e.g. closure with sealing ring). When the components are injected into each other, the so-called sandwich technique, a multi-layer structure is produced, e.g. soft outer skin over a hard core or recycled material on the inside, new material on the outside for high-quality surfaces.

Your benefits.

For all their diversity, most multi-component processes offer similar advantages:


  • Cycle times are considerably reduced
  • Machine setup is easier and faster compared to two mono machines
  • Operations are simplified
  • Assembly effort is reduced
  • Quality assurance and reproducibility increased
  • Less space required
  • Reduced energy consumption
