Gas Assisted Injection Moulding

The principle of this process is that nitrogen gas is injected, during the moulding cycle, either through the sprue or directly into the mould tool. At a controlled high pressure this has the benefit of overcoming sink marks or introducing a cavity without the requirement of a core

Benefits of Gas Assisted Injection Moulding

  • Reduced material requirements
  • Reduced cycle times
  • Reduced wear on moulds
  • Improved component quality
