Such as Dongguan Da Ling Shan Chang Sheng new materials and processing hardware store outlet back charge ratio, the charge should not exceed 50 percent return, most of the new material: old material = 70:30. Continuous melting alloy of aluminum and magnesium decreased. Zinc alloy remelting outlet material, must be strictly controlled melting temperature should not exceed 420 ℃, in order to avoid loss of aluminum and magnesium. Conditional best casting plant centralized melting furnace zinc alloy, the alloy ingot and back charge uniform ratio HDMI, flux can be more effective use of zinc alloy pins EU regulations, the alloy composition and the temperature is kept uniform and stable. Electroplating waste, fines should be a separate furnace. Dongguan Da Ling Shan Chang Sheng processing hardware store zinc alloy main elements are aluminum, copper and magnesium. Zinc Alloy process can be divided into two types of deformation and cast zinc alloy. Cast zinc alloy and corrosion resistance compared with liquidity Good zinc alloy die for die-casting instrumentation, automotive parts such as Shell. Features 1. ingredient quality compared significance. 2. There is a good room temperature mechanical properties and wear resistance. 3 .. low melting point, melting at 385 ℃, easy casting.
