Mold design and development of zinc alloy die casting, die casting is a use of coercion to a sophisticated hydraulic casting molten metal into a mold in the shape of complex, zinc alloy die casting than other molding process, to make a good With a good casting products are not die-casting machine can and must be mold, die-casting machine, die-casting process combined with each other in order to make a good product. The production of zinc alloy die casting, there are many details that need attention, such as zinc alloy die castings should check from the purchase of raw materials, the ratio of raw materials, etc. are a very important part, particularly in the production of zinc alloy die castings in pay attention to what the problem, take a look below.

1, the control starts with the purchase of alloy composition alloy ingots, alloy ingots must be based on special high-grade zinc-based, with ultra-high-purity aluminum, magnesium, copper formulated into ingots, supplier strict ingredient standards. Quality zinc alloy material is guaranteed to produce quality castings. 

2, procuring alloy ingots to ensure there is clean, dry stacking area to avoid prolonged exposure to moisture and white rust, dirt or plants to increase pollution generated slag also increased metal loss. Clean factory environment effective control of the alloy composition is useful role. 

3, new materials and the outlet back to charge ratio, return the charge should not exceed 50 percent, most of the new material: old material = 70: 30. Continuous remelting alloy of aluminum and magnesium decreased. 

4, the outlet material remelting, must be strictly controlled remelting temperature should not exceed 430 ℃, in order to avoid loss of aluminum and magnesium. 

5, metal casting plant conditions preferably concentrated zinc alloy melting furnace, the alloy ingot and return even charge ratio, flux can be more effective use of the alloy composition and the temperature is kept uniform and stable. Electroplating waste, fines should be a separate furnace.
