Dongguan Da Ling Shan Chang Sheng processing hardware store zinc alloy die casting should not be used at high temperature and low temperature (0 ℃ below) work environment. Zinc alloy at room temperature have good mechanical properties. However, at high temperature impact properties were significantly decreased under tensile strength and low temperatures. Zinc alloy die castings due to insufficient clamping force, clamping bad, inadequate mold strength, high temperature molten metal surface and other issues will be glitches phenomenon HDMI, this phenomenon is called product burr, often after companies must face Processing processing operations are mainly based on the use of hand-polished nature of the product, hydrogen explosions and 昭凌 freezer blasting machine to solve Dongguan Da Ling Shan Chang Sheng processing hardware store impurity elements: lead, cadmium, zinc, tin alloy intergranular become sensitive to corrosion, accelerated intergranular corrosion of zinc alloy itself British regulatory pins, reducing mechanical properties and dimensional changes in temperature caused by the casting, wet environment. When zinc alloy impurity elements such as lead, cadmium and zinc alloy content is too high, the workpiece just casting zinc alloy pin EU regulations, surface quality as usual, but is stored at room temperature for a period of time (eight weeks to a few months), the surface of the drum bubble. Zinc alloy plate, Chang Sheng Hardware (certified), zinc alloy provided by Dongguan Da Ling Shan Chang Sheng processing hardware store. Dongguan Da Ling Shan Chang Sheng processing hardware store (shop1379091614724.1688.com) is Dongguan, hardware accessories leader, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs.
