HIPS'in proses \u00f6zellikleri<\/span><\/h3>\n

HIPS is known for its rubber-like qualities, which inform the injection molding requirements. For instance, temperature must be set higher and a slower cooling rate necessitates extra holding pressure, time and intervals during production. <\/p>\n

Bu re\u00e7ine nemi yava\u015f emdi\u011finden, 190 ila 240\u00b0C aras\u0131ndaki i\u015fleme s\u0131cakl\u0131klar\u0131n\u0131n uygulanmas\u0131ndan \u00f6nce kurutma gerektirmemelidir.

A\u015f\u0131r\u0131 nem emilimi, nihai \u00fcr\u00fcn \u00fczerinde zararl\u0131 bir etki yaratarak \u00fcr\u00fcn\u00fcn ho\u015f g\u00f6r\u00fcnmemesine neden olabilir. <\/p>\n

To mitigate these effects, injection mold temperature must be raised while holding pressure reduced- carefully balancing those conditions with adequate clamping force will provide an ideal environment for successful production without unwanted water traps appearing.<\/p>\n
