Ingot casting of material of frame of down-lead of the first electron of domesti
From;  Author:Stand originally
Copperplate of aluminous big smelt metal heads group of heat of frame of down-lead of limited company electron in, successful mould gives ingot casting of material of frame of down-lead of electron of the first C19400 of domestic, product quality achieves international advanced level, fill the blank of domestic congener product.
Contain iron as a result of material of frame of down-lead of electron of C19400 copper alloy the volume is higher, the control difficulty that metallic part is distributed equably is great, the home before this did not reach the congener product production of international quality standard. The guidance of outer square expert leaves this company, victory of first ingot casting is born.
