Dongguan Da Ling Shan Chang Sheng processing hardware store Reuters international cast zinc alloy industry, in recent years, China's rapid development of zinc alloy die-casting technology zinc alloy products processing plant, the economic benefits of market efficiency can not be underestimated, according to experts, zinc alloy die-casting technology has the following characteristics: a relatively large proportion. 2, good casting performance, complex die-cast shapes, thin-walled precision castings, smooth surface. 3, may be subjected to surface treatment: electroplating, painting, painting, polishing, grinding and the like. 4, do not smoke when melted and die cast iron, corrosion-pressure, non-stick mold. 5, there is a good room temperature mechanical properties and wear resistance. 6, low melting point, easy casting. Dongguan Da Ling Shan Chang Sheng processing hardware store to resolve deficiencies solutions: control stomata produce, the key is to reduce the amount of gas mixed cast zinc alloy jewelry inside, ideal metal flow should continue to accelerate through the shunt by the nozzle cone and the runner into the cavity to form a smooth and consistent direction of metal flow, tapered channel design, which should continue to accelerate the flow of water from the nozzle to the gate inward gradually decreased, can achieve this goal. In the filling system, the mixed gas is due to turbulent mixing with the molten metal to form pores, from a study molten metal casting system into the mold cavity by casting simulation process, the apparent runner sharp transition bit and incrementing the pouring Road sectional area of ??supply of zinc alloy jewelry, metal flow will cause turbulence and the volume of gas occurs, can help smooth the liquid metal into the overflow tank and exhaust gas tank from the sprue and cavity mold discharged outside.
