2K injection molding

Two-component injection molding in one operation

Another core competence of Plastium GmbH is the production of direct bonded molded parts in the variants:

  • Thermoplastic and thermoplastic elastomer (plastic & TPE)
  • Combination of two thermoplastics (plastic & plastic)
  • Thermoplastic and silicone

The applications of these composite molded parts are very diverse and offer decisive cost and functional advantages.
