Control of internal shape by gas injection
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
