GAS INJECTION TECHNOLOGY
Available from Herzog Injection Technology, Inc.
The gas searches the easiest way through the soft core of the injected part and displaces the mass until the cavity is filled out.
Since the initial attempts with Gas / Water injection technology, the company Herzog AG has successfully set itself apart with gas introduction components (injectors and machine nozzles).
The machine nozzle is used here, where the gas introduction is to be made by the sprue bushing. This has the advantage that no adjustments must be made at the mold. The resulting opening at the injected part from the gas introduction, can be closed by postinjection.
