Select Choose what kind of zinc alloy, mainly from three aspects to consider casting their own purposes, you need to meet performance requirements. Comprising: (1) the mechanical characteristics of the zinc alloy handle, the tensile strength, the maximum resistance material at break; elongation, are brittle materials and plastic metrics; hardness, the material is pressed into the surface of a hard object or friction caused by The plastic deformation resistance. (2) the state of the working environment: temperature, humidity, the workpiece contact media and air tightness requirements. (3) accuracy: accuracy and dimensional stability can be achieved. Such as Dongguan Da Ling Shan Chang Sheng new materials and processing hardware store outlet back charge ratio of zinc alloy die-casting, back charge not to exceed 50% HDMI, most of the new material: old material = 70:30. Continuous melting alloy of aluminum and magnesium decreased. When the outlet material melting, we must strictly control the melting temperature should not exceed 420 ℃ zinc alloy, 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, 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. Zinc alloy zinc alloy jewelry _ _ Chang Sheng Hardware provided by Dongguan Da Ling Shan Chang Sheng processing hardware store.
