I-Zinc die casting design usizo / izinsizakalo zobunjiniyela ezihambisanayo. Umenzi wangokwezifiso we-precision zinc die castings. Ukusakazwa okuncane, ukukhishwa kwengcindezi ephezulu, ukusikeka kwesikhunta esiningi, ukujikijelwa kwesikhunta okuvamile, ukufefa kwamayunithi kanye nokuzimela okuzimele kanye nokuvalwa okuvaliwe komgodi kungenziwa. Ama-Castings angenziwa ngobude nobubanzi obufinyelela ku-24 in. Ku +/- 0.0005 in. Ukubekezelelana.

Umkhiqizi oqinisekisiwe we-ISO 9001 2015 we-die cast magnesium nokukhiqizwa kwesikhunta

I-ISO 9001: Umkhiqizi oqinisekisiwe ka-2015 we-die cast magnesium, Amandla afaka i-high-pressure magnesium die casting up to 200 ton chamber hot & 3000 ton cold chamber, designing designing, polishing, molding, machining, powder & liquid paint, QA full with CMM amakhono , inhlangano, ukupakisha nokulethwa.

Ukulingiswa kweMinghe Ukulingisa okungeziwe kwe-Service-investing njll

Kuqinisekiswe i-ITAF16949. Insiza Eyengeziwe Yokulingisa Faka ukukhipha utshalomali,ukuphonsa kwesihlabathi,Ukuphonswa kwamandla, Lost Foam Ekubunjweni,I-Centrifugal Casting,Ukuphoswa Kokuqothula,Permanent Isikhunta Ukulingisa, Amakhono afaka i-EDI, usizo lobunjiniyela, ukumodeliswa okuqinile nokucutshungulwa kwesibili.
