Gas Injection Moulding

In this N2 gas at low pressure is utilized to apply uniform pressure on molded plastic parts. N2 gas can come in contact with melts at high temperature without difficulty.

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.

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