China automobile die casting parts manufacturer market prospects

     At present, China's economic situation is generally good. China automobile die casting parts manufacturer to develop smoothly. 2009 GDP growth of 8.7%; the expansion of domestic demand, the national implementation of the total amount of 4 trillion yuan of investment plans for two years, ten industrial restructuring and revitalization plan, for the die casting industry provides a broad space for development. Especially automobile industry planning objectives: from 2009 to 2011, the average growth rate reached 10%, more than 90% of China's automotive products in domestic sales, has little impact on the international market.
     In addition, the implementation of the revitalization of the industry, such as motorcycles, electrical appliances, telecommunications, home appliances hardware, electrical and mechanical instruments, light industry and other industries, have provided new opportunities for the survival and development of China die casting manufacturer.

The process requirements of the zamak die casting manufacture

     Zamak die casting manufacture commonly used material is 3# zinc alloy. There are these requirements for the production process:
     1. There will be a pin hole mark on the product. The ejector pin is in the right position. Try to make the product demoulding force uniform, avoid product distortion.
     2. Die casting mold must have a feed port and a discharge port, channel thickness is generally 3 to 4 mm, the width is 6 to 10 mm, the inclination of 10 degrees, into the feed inlet thickness is 0.25 mm.
     3. The product internal buckle position of the product needs to make the lifter. The thickness of the inclined top is 5.5 mm above, in order to ensure its strength, the angle is 3 degrees to 8 degrees.
     4. Zamak die casting products similar in other mould making products, need to have the pattern draft, the general is 0.5 degrees to 5 degrees between (according to the product structure height). The pattern draft is too small to affect the mold and deformation, but it can not be too large, otherwise the influence of assembly.
     5. Product allows local minimum wall thickness is 0.3 mm, the average wall thickness is generally 0.8 mm or more, turning point try to do more than 0.5 mm fillet.

Anti burning technology of magnesium die casting manufacturing

    1. The salt flux: metal melt with chloride caused pollution and salt vapor on the surrounding environment caused by damage, not adapted to the modern large quantities of magnesium die casting manufacturing.
    2. At present, SF6 is the basic and indispensable protective gas, but only in the sealing furnace the effect is good. SF6 the only drawback is that it will produce a greenhouse effect.
    3. SO2 as a protective gas, simple and practical, can be mixed with SF6.
    4. The inert gas argon, helium nitrogen is used alone can't inhibit Mg evaporation in the atmosphere, but it can play a role in the whole closed function of the furnace..
    5. To improve the oxidation state, to add elements of Be, Ca, Zn, can change the performance of magnesium alloy casting, on the mechanical properties also influence for magnesium die casting, which the effect of Be is the best, do not affect the cutting performance of the material.

Importance of automobile die casting manufacturer

     According to the report (in the United States as an example), at the beginning of 1980s, the average weight of each car produced by automobile die casting manufacturer is within the range of 1315 to 1542KG, then gradually decreasing. But the amount of aluminum alloy castings in each car is gradually increasing. 1980 average each car is 34KG, 1990 it is 68KG, 2000 it increased to 111.3KG, 2009 it reached 157KG, in which the aluminum alloy die-casting parts accounted for more than 65% of all castings.
     In addition, in addition to aluminum alloy die castings, but also the use of zinc alloy, magnesium alloy and copper alloy die castings, it is obvious that the amount of die castings in each car. Die casting industry is closely related to automobile industry.
     Recalling the history of the development of automobile industry in the world, in various parts of the design and application process, attaches great importance to the adoption of die-casting parts, especially complex, large and important parts, is usually as a major research topic. This not only shows the irreplaceable of the die casting industry in this aspect, but also highlights that the development of the die casting manufacturer is largely based on the automobile industry. In other words, the die casting industry is one of the important supporting industries for the automobile industry.

The raw material of the zinc die casting phone shell

    In the zinc alloy mobile shell products, choose the right raw material can guarantee the product quality and improve the output. The raw material for zinc die casting phone shell is zinc 3#, zinc 5#, zinc 7#, zinc 8#. From the purchase cost considerations: the general use of zinc 3#; the higher strength of the products using zinc 5#; high resistance to deformation and wear resistant components are required for zinc 8#.
    Because of the low content of copper in zinc 3#, the mechanical properties of the weak parts of the product are low, and the product is easily deformed.. Zinc 5# copper content of about 1%, the intensity of the product has a substantial increase, but still did not achieve the ideal of the qualified rate. The product of zinc 8# production, the qualified rate is greatly improved, because of the high aluminum content in the 8# raw materials, has the stable anti deformation capacity and high comprehensive performance. Thus, we should choose zinc alloy die casting raw material according to the structure and the use of the product, so as to achieve the satisfactory quality and the cost benefit.
