Hangarau graphite/Jigs/whakapapa mo nga Whakapiri Semiconductor na te hiri Kaata-ki-Metal
Ko nga ahuatanga o to maatau graphite mold:
1. Ko nga maaka kawhata tetahi o nga mea tino wera i tenei wa.
2. Ma te pai o te awangawanga waiariki, kaore he kapiti ka puta ina he wera me te makariri te pāmahana
3. He pai te kawe i te waiariki me nga ahuatanga kawe
4. Pai whakahinuhinu me abrasion ātete
5. Te pumau matū, te aukati waikawa me te alkali me te aukati waikura, ehara i te mea ngawari ki te urupare me te nuinga o nga konganuku
6. Ka taea e te wheketere te hanga i te graphite sintering mold He ngawari ki te tukatuka, he pai te mahi tukatuka miihini, ka taea te hanga i te hanga matatini me te hangai tino tika.
Taupānga
Ko te hangahanga graphite kua whakamahia nuitia i roto i nga waahanga e whai ake nei:
1.Continuous makanga pokepokea ai
2.Pressure whakarewa pokepokea ai
3.Glass niao ki te mate
4.Sintering pokepokea ai
5.Centrifugal makanga pokepokea ai
6. He koura, he hiriwa, he whakapaipai……
