The development trend of China metal stamping parts supplier

    Chinese metal stamping product variety, excellent quality, the price is reasonable. China metal stamping parts supplier with good reputation, enthusiastic service and years of accumulated precipitation of large sales network group, has been gradually entered the domestic provinces and cities, and the Middle East, South Asia, Uruguay, Kazakhstan, Africa market ect.
    Since 2010, as the impact of the financial crisis weakened gradually, a lot of metal stamping processing trade appeared warms up trend, the rapid recovery in the international economy, to further promote the China hardware stamping products export development, but also to the China metal stamping industry greater room for development. Strong domestic market demand and foreign markets continue to expand to create a good development space for the metal stamping parts supplier.

What are the zamak die casting material composition

    Zamak die casting material is to add other elements in zinc. Often added alloying elements are aluminum, copper, magnesium, cadmium, lead, and titanium.
    Zinc alloy with low melting point, good fluidity, easy welding, brazing and plastic processing, corrosion resistance in the atmosphere, the residual waste easy recycling and remelting; but the creep strength low, prone to natural aging cause dimensional changes.
    The melt preparation, casting or pressure forming. According to the manufacturing process can be divided into the zamak die casting and deformation zinc alloy.

Prospect of die casting manufacturer

    In this century, China has become the second largest Auto producer, but also motorcycles, the largest producer of metal products, die casting industry is the supporting industry of the above three big industry indispensable, the development prospect of casting manufacturer is very broad.
    With the development of modern science and technology, die casting industry put forward more requirements on the number of products, quality and varieties, die casting manufacturer to introduce advanced technology and management mode, and realize intelligent and automatic die casting production, for the optimization of die casting process, improve the economic and technical index of the die casting workshop, enhance the ability to produce high performance high precision casting, plays a very important role.

What are the properties of die cast zinc alloy

    Die cast zinc alloy properties: mechanical properties of zinc alloy and electroplating properties are very good. The surface of zinc alloy die castings of roughness, strength and elongation are very good. Due to the mobility of zinc is so good can do thin products (wall thickness can be 0.5). Defects of zinc is the largest proportion is too large, the weight and the cost of the product is high, suitable for small products. At the same time, zinc alloy poor dimensional stability.
1) Specific gravity: pure zinc: 6.6g / cm3; die-cast zinc alloy: 6.7-6.9g / cm3;
2) Melting point: pure zinc: 419 °C; zinc alloy: 387-390 °C; Die Casting temperature: 390-410 °C.
3) Zinc die casting type most commonly used is 3 # zinc alloy (ZAMAK 3).

What are the characteristics of zinc alloy die casting

  You want to do the high quality zinc alloy die casting product, only then the good die-casting machine is insufficient, must be the mold, the die-casting machine, the compression casting craft unifies mutually, so that you can make a good product. Product characteristics of zinc alloy die casting:
1. Than the major, has weight and texture, its strength greater than plastic injection molding.
2. The casting property is good, you can die-cast complex shape and thin wall precision parts, the casting surface is smooth.  
3. Zamak die casting can be surface treatment: electroplating, painting, painting.
4. When melting and compression casting, it does not attract the iron, does not corrode the mold, does not stick the mold.
5. Has good mechanical properties and wear resistance at room temperature.
6. Low melting point, melting at 385 °C. It is easier molding than the aluminum alloy die-casting.

The development history of aluminum die casting

      The development history of aluminum die casting is public opinions are divergent. According to the relevant articles, initially there is a lead die casting. In 1822, Willam Church made casting machine daily production 1.2~2 million of the type. In the twenty years later, J.J.Sturgiss is designed and created the first piston operated hot chamber die casting machine, and obtained a patent in American. In 1885, Merck Gense Le study the previous patent, invention of printing die casting machine. In nineteenth Century 60 time for zinc alloy die-casting parts production. Die casting is widely used in industrial production is just at the beginning of the last century. In 1905 the H.H.Doehler developed for the industrial production of die casting machine, die cast zinc, tin, copper alloy castings. Then Wagner designed gooseneck pressure die casting machine for the production of aluminum die casting.
