Our factory specializes in the production of die-cast metal products processing hardware accessories zinc alloy products deserve plug bracket feet: there are two circular needles, just connect FireWire (L) and neutral (N), a non-ground. Typically such plugs can be inserted into the socket in either direction, leaving the plug can be free to change the location of the hot and neutral lines. Generally pin sizes: 4.0mm zinc alloy, 4.8mm, 5.0mm pin plug bracket: There three circular needle zinc alloy products processing plant, connecting FireWire (L) and neutral (N) zinc alloy jewelry, grounding. Usually only one direction a plug can be inserted into the socket, general pins sizes: 4.0mm, 5.0mm, 7.0mm, 8.7mm Dongguan Da Ling Shan Chang Sheng processing hardware store for shrinkage: To die casting solidification process At the same time in various parts of the heat evenly as possible, while solidifying. Outlet through rational design, the gate thickness and position of zinc alloy British regulatory pins, mold design, mold temperature control and cooling, to avoid shrinkage produce. For intergranular corrosion phenomena: the main control alloy materials harmful impurities, particularly lead <0.003%. Note that the waste caused by impurity elements. For waterlines, cold shut lines, can improve the mold temperature, increasing the speed of the gate, or an increase in septal area overflow tank in the cold, cold traps to reduce the appearance of lines. For hot crack: casting thickness not produce dramatic changes in order to reduce stress; casting process parameters related adjustments; lower mold temperature. Zinc alloy products processing plants, zinc alloy, Chang Sheng Hardware provided by Dongguan Da Ling Shan Chang Sheng processing hardware store.
