Die-cast zinc alloy
The molten state of zinc alloy is very fluid, with a low melting point of only 365 度. Various post-processing treatments such as electroplating can be performed, so it is widely used. It was also used a lot in the mobile phone industry before, but because of its large specific weight and poor corrosion resistance, it was gradually eliminated by aluminum alloys. The most used is the bathroom industry. Commonly used are 2, 3, 4, 5, 7 zinc alloys, 最廣泛使用的是 3 zinc alloys.
壓鑄鋁合金
鋁合金密度低, 但強度相對較高, 接近或超過優質鋼材, 可塑性好, 並可加工成各種型材. 它具有優良的導電性, 導熱性和耐腐蝕性, 並廣泛應用於工業領域, 僅次於鋼鐵. 鋁合金的比重僅為 1/3 鐵的, 所以在各行各業都非常重要, 尤其是在飛機輕量化進程中, 船舶, 汽車, 和電子儀器.
常用的是Al-Si-Cu系, 一般ADC12 (A383), 類比數位轉換器10 (空中巴士380) 等等. 另外, 有Al-Si系列, 鋁矽鎂系列, 和鋁鎂系列. 又稱鋁鈦合金, 在上述材料中添加鈦金屬進行改進. Adding titanium metal can significantly improve the mechanical properties of the product.
Die-cast magnesium alloy
Magnesium alloys are alloys composed of magnesium-based and other elements. Its characteristics are:
Low density, high specific strength, large specific elastic modulus, good heat dissipation, good shock absorption, higher impact load capacity than aluminum alloy, and good corrosion resistance to organic substances and alkalis. The specific gravity of magnesium is about 2/3 that of aluminum and 1/4 鐵的. 所以, it is widely used in electronic equipment such as mobile phones, communication equipment, 汽車零件, and medical equipment.
The most widely used are magnesium-aluminum alloys, followed by magnesium-manganese alloys and magnesium-zinc-zirconium alloys. The commonly used grades are AZ91D, AM60B, AM50A, AS41B and so on.
Die casting mold
Die-casting molds must be made of hot work mold steel. Commonly used steels are: H13, 2344, 8407, 8418, SKD61, DAC, FDAC, ETC.
Mold structure: (rear mold, front mold) mold base, mold core, guide post, guide sleeve thimble, 圓柱, shunt, gate sleeve, slider, inclined guide post, hydraulic core pulling.
Mold processing equipment: milling machine, CNC加工中心, 線切割 (slow wire), (mirror) spark machine, grinding machine, lathe, welding repair equipment.
