PLASTINUM Gas Injection Moulding with CO₂

Replacing nitrogen with carbon dioxide for added efficiency gains

Our patented PLASTINUM® Gas Injection Moulding (GIM) with CO2 solution takes efficiency to the next level by replacing gaseous nitrogen (N2) with liquid carbon dioxide (CO2). While matching the heat removal capacity and cycle times of water injection moulding, carbon dioxide does not leave any moisture on the products or tools, thus eliminating an additional drying step in the fluid injection cycle. CO2 has a much greater cooling capacity than nitrogen due to its much higher density, higher specific heat capacity and high expansion cooling capacity during depressurisation at the end of the cycle. This allows the part to cool down much more quickly. Gas injection moulding installations that use CO2 not only require a suitable carbon dioxide supply scheme, they also need pressure and control modules and gas injectors that are optimised for CO2.

To meet these needs, we developed our PLASTINUM GIM CO2 pressure control units and injectors in close collaboration with our OEM partners.


  • Enhanced cooling power
  • Cycle times accelerated by up to 40%
  • Elimination of water handling issues associated with water injection moulding
