Manufacturing technology of alloy button
1. plaster to make a large proportion of the cross, then copy a frame model with resin, this sturdy, carved out of the same specification of brass buttons. Button tubes commonly known as copper, placed on the spark machine, using electrodes to child button. Then etching on the steel, copper and steel-filled with a liquid oil cooling temperature, steel must be heat treated, can be mass produced.
2. after 430 °-450 ° c high temperature alloy block will melt into a liquid, by high pressure injection machines, alloy hydraulic pressure into steel moulds, die open, alloy buttons fall off, machine control die of opening and closing. will be churning out cheap buttons.
