What are the characteristics of zinc alloy die casting? The main characteristics of zinc alloy die casting are - The melting point of zinc alloy is low, when the temperature reaches four hundred degrees zinc alloy produces melting process, which is better for molding in zinc alloy die casting. Zinc alloy in the melting and die-casting process does not absorb iron, and zinc alloy casting performance is good, in the die-casting process can put a lot of complex shape of precision parts, the surface of the casting after the completion of die-casting looks very smooth. At the same time, the specific gravity of zinc alloy is relatively large. Zinc alloy die-casting technology is widely used in the injection molding process, its main advantage is in focusing on improving the quality of the casting. Anyone who knows about zinc die casting knows that the runners and remnants are part of the casting, and they have little value in the casting, but they are still factored into the cost of the casting. At the same time the alloy is recyclable, generally in the will be returned to the original supplier in exchange for new material. If the supplier does not handle the material well, then it will lead to air pollution, which will bring environmental hazards. There are many other ways to recycle zinc alloy die casting, and zinc alloy die casting is an alloy composed of zinc as the main element, and some other alloy elements, like aluminum, copper, etc. The manufacturing process of zinc alloy die casting is usually divided into two types, one for casting zinc alloy and one for deforming zinc alloy. Each of them has different characteri stics for zinc alloy casting.

Aluminum alloy die-casting process and mold technology development status analysis After the 1990s, China's die-casting industry has made amazing development and has developed into a new industry. At present, the aluminum alloy die-casting process has become one of the most widely used processes in the automotive aluminum alloy forming process, accounting for 49% of the various automotive molding process methods. China's existing die-casting enterprises about 3,000, die casting production from 266,000 tons in 1995 rose to 870,000 tons in 2005, the annual growth rate remained at more than 20%, of which aluminum alloy die casting accounted for all die casting production of more than 3/4. The types of die casting products in China are diversified, including automobiles, motorcycles, communications, home appliances, hardware products, power tools, IT, lighting, escalator steps, toy lights, etc.. With the improvement of technology level and product development ability, die-casting product types and application fields are expanding, its die-casting equipment, die-casting mold and die-casting process have undergone great changes. Die-casting aluminum alloy die-casting aluminum alloy since 1914 into commercial production, with the development of the automotive industry and the invention of cold chamber die-casting machine, has been rapid development. The die-casting aluminum alloy is divided into two kinds according to the performance: low and medium strength (such as China's Y102) and high strength (such as China's Y112). At present, the industrial application of die-casting aluminum alloy mainly has the following series: Al-Si, Al-Mg, Al-Si-Cu, Al-Si-Mg, Al-Si-Cu-Mg, Al-Zn and so on. The improvement of mechanical properties of die-casting aluminum alloy is often accompanied by the reduction of casting process performance, pressure casting because of its high-pressure rapid solidification characteristics make this contradiction in some aspects more prominent, so the general die casting is difficult to solid solution heat treatment, which restricts the improvement of mechanical properties of die-casting aluminum alloy, although oxygen-filled die-casting, vacuum die-casting, etc. is an effective way to improve the mechanical properties of the alloy, but there is still some difficulty in the widespread adoption Therefore, the develop

Characteristics of magnesium alloy die casting In most cases, magnesium die castings produce products similar to other alloy die castings. Magnesium alloy die casting die is also similar to aluminum and zinc alloy die casting die. But due to some characteristics of magnesium alloy different from aluminum alloy, give consideration when designing die casting die, in order to design a reasonable die casting die, so as to produce magnesium alloy die casting efficiently and economically. The characteristics of magnesium alloys 1, light magnesium specific gravity of only 1.8G/CM3, aluminum alloy specific gravity of 2.7G/CM3, magnesium alloy is 30% lighter than aluminum alloy, 80% lighter than steel. Therefore, the car and handheld electronic products in magnesium alloy has become the ideal material for parts manufacturing. 2, strength magnesium alloy in metal and plastic and other engineering materials, has a relatively good strength / weight ratio. 3, die-casting properties in maintaining good structural conditions, magnesium alloy allows the casting wall thickness can reach 0.6 MM, which is the same strength of plastic can not reach. Aluminum alloy die-casting performance also to be in 1.2-1.5MM above when compared with magnesium alloy. Magnesium alloy is easier to die-casting molding, suitable for high-volume die-casting production (production speed up to 1.5 times of aluminum). In addition, magnesium alloy mold wear is also lower than aluminum. 4, shock magnesium absorption has very good stagnation and shock absorption performance, can absorb vibration and noise, used as equipment housing can reduce noise transmission, free from impact and prevent dent damage. 5, rigid magnesium rigidity for aluminum 2 times and higher than most of the plastic. Magnesium has good resistance to stress resistance. 6, high electromagnetic interference magnesium alloy has a good function of blocking electromagnetic waves, suitable for the production of electronic products. 7, good cutting performance magnesium than aluminum and zinc have better cutting, so that magnesium becomes easier to cut and process metal materials. 8, the specific heat capacity of magnesium alloy is small, the cooling speed of the alloy liquid. 9, magnesium alloy and mold steel affinity is small, not easy to adhere to the mold.
