Awọn ohun elo ti o wulo fun sisọ abẹrẹ irin
Ilana MIM wulo fun awọn ohun elo ti o pọju, pẹlu irin alloy kekere, irin alagbara, irin ọpa, alloy nickel alloy, alloy tungsten, alloy lile, alloy titanium, awọn ohun elo magnetic, Kovar alloy, awọn ohun elo amọ, ati bẹbẹ lọ.
Iru awọn ọja irin wo ni o dara fun ilana MIM:
1. Iwọn paati MIM nigbagbogbo jẹ 0.2g - 200g.
2. Agbegbe akanṣe jẹ 100 square centimeters.
3. Iwọn iwọn awọn ẹya MIM ti o wa loke 10MM jẹ ± 0.5%.
4. Awọn ẹya MIM ti o pọju sisanra odi jẹ 10MM.
5. Iwọn to kere ju 0.2MM.
