Maximum design freedom

High-quality multi-colour design, lower-cost parts, complex moulded parts comprising two or more components. All of these factors have contributed to the rapid adoption of multi-component moulding. It involves injecting two or more different materials into the same mould in a sequential or simultaneous manner to create a single product. This process is widely used in the automotive, electronics, consumables and medical industries, where functionality, highest quality, or aesthetically-pleasing products are in high demand.

  1. Turntable process – production of multiple component parts through turning of the ejector side
  2. Index platen – production of multiple component parts through transferring the article from one cavity to further cavities
  3. Bi-injection moulding – simultaneous or delayed injection of two components into the same cavity
  4. Core-back process – injection of two components into one cavity in sequence; cavity for second component is released by pulling a gate-valve
  5. Transfer process – preform is transferred manually or by robot to the second cavity or second machine
  1. Reduced assembly effort
  2. Increased quality assurance and reproducibility
  3. Less floor space and less machine setup time required
  4. Reduced energy consumption
  5. No compromises in application design (haptics, colours, materials)
  1. Consumer goods/Automotive industry - Products with multiple colours, materials or haptics features
  2. Automotive/Medical/Electronics industry - Functional parts with special features
