Ngā Tohu Hua
Kei a Ningbo De-Shin te whānuitanga katoa o te parahi tungsten (6~50wt.% Cu) mō ngā momo tono ahumahi rerekē. Ka whakamahia te tukanga whakaurunga korehau matatau, ā, ka tutuki i ngā hua katoa ngā paearu o GB/T 8320-2003, ASTM B 702-93 (Whakaaetia anō 2004). He rūpahu-konumohe te parahi tungsten, ā, kei a ia te kaha ātete kakahu o te tungsten me te kawe hiko teitei o te parahi.
Tukanga whakaputa:ranunga paura –> pēhi –> sintering –> whakaurunga korehau –> mīhini –> QC. Ko tēnei tukanga whakaputa katoa e tino whakahaerehia ana e QC kia pai ai te kounga o te mahi.
Ngā Painga:
1. He ātete pewa teitei me te kawe hiko pai.
2. Te kawe wera teitei.
3. He iti te horapa o te wera.
Ngā tono:
1. Te whakapūngao i ngā hononga hiko me ngā hononga korehau i roto i ngā kaiwawao hiko teitei me te reo, i ngā kaiwhakamutu hiko rānei.
2. Ngā irahiko i roto i ngā mīhini tapahi hiko mō te horo o te mura.
3. Whakaaturanga Hua! Ngā totohu wera hei wāhanga whakamatao kore mahi o ngā taputapu hiko me ngā rauemi takai hiko.
4. Ngā irahiko mō te whakarewa ātete.
Rahi o te taonga:
Tokotoko parahi tungsten: diameter≥0.5mm; roa≤300mm.
Pereti parahi tungsten: matotoru ≥1.0mm; roa me te whānui ≤300mm.
