Detailed Product Description: | 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 within the mixed cast, the ideal metal flow should continue to accelerate through the shunt by the nozzle cone and 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 EU regulations gradually reduced zinc alloy pins, 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 channel cross-sectional area, would appear to make the metal flow turbulence gas volumes of zinc alloy, can help smooth the liquid metal into the overflow tank and exhaust gas tank from the sprue and cavity mold discharged outside. Dongguan Da Ling Shan Chang Sheng processing hardware store zinc and aluminum die casting is ── kinds of zinc die casting parts as the main component. This part surface ── very dense surface layer, which is the evacuation of the porous structure, but also a lively amphoteric metal. Therefore, only the use of appropriate pre-treatment methods and plating process, in order to ensure on zinc alloy plating layer with good adhesion, meet the requirements of qualified products. Plating zinc alloy commonly used for ZA4-1, the main component: aluminum 3.5% to 4.5% copper 0.75% ~ 1.25%, Guangdong zinc alloy products, magnesium 0.03% to 0.08% and the balance of zinc, the sum of impurities ≤0.2 %. The amount of copper-zinc alloy 925 high grades, but also easy to plating. Typically, the density of zinc alloy is 6.4 ~ 6.5 g / cm, if the density of <6.4 g / cm, prone to blistering and pitting after plating. In short PRD zinc alloy die-casting, when the selection must strictly. In addition, die-casting mold must be designed to avoid to bring insurmountable plating defects (such as pitting). Which strong zinc alloy die-casting, zinc alloy, Chang Sheng Hardware provided by Dongguan Da Ling Shan Chang Sheng processing hardware store. Dongguan Da Ling Shan Chang Sheng processing hardware store (shop1379091614724.1688.com) strong, credible, in Dongguan, Guangdong and other hardware accessories industry has accumulated a large number of loyal customers. The company better work attitude and constantly improving innovative ideas will lead Chang Sheng Hardware and you hand into the brilliant, for a better future! |
