User manual BAUER GAS INJECTION TECHNOLOGY BROCHURE

[. . . ] After filling the part cavity at 100% with polymer, the gas is injected under pressure and the overflow cavity is open to collect the superfluous plastic. The gas ensures the holding phase pressure during cooling and is purged immediately before opening the mould. Gas 3 Gas BENEfITS Of GIT The use of gas assisted injection technology allows production of technical parts with the appearance of superior quality. The manufacturing process is also more efficient, improving productivity and thus significantly increasing profitability. A better quality of injected part: - High strength and rigidity - Dimensional stability, no warpage - Elimination of sink marks - No assembly, single parts Simplification of tools Freedom in design Lower clamping force (in partial) Reduced cycle time Material saving Realization of hollow (pipe) GIT-sysTEms BAUER EXPERIENCE Our outstanding expertise in purifying gases coupled with software-based control technology developed by our BAUER specialists guarantee you outstanding product quality which will improve profitability.
