According to the latest statistics from the China Association of Automobile Manufacturers, the total output of automobile parts in Linzhou, Henan Province accounts for about 40% of the nation's zero-sales market for heavy trucks. Among them, the output of clawed spines of automobile generators accounts for about 70% of the national market share, and it has become the largest in the country. County (city) level auto parts production base.
Up to now, there are more than 350 large-scale auto parts enterprises in Linzhou City with more than 30,000 employees. The annual production capacity is more than 400,000 tons of castings and 150,000 water tanks, with an annual output value of 3 billion yuan. Auto parts products mainly include automobile chassis, brake parts, engine block cylinder heads, generator claws ratchets, and car water tanks, forming more than 2,000 varieties of eight models and ten series. Auto parts products cover 28 provinces, cities, and autonomous regions in the country, and some of them are exported to Japan, South Korea, the United States and other countries.
Zinc Alloy Die Casting have a good surface roughness, strength and elongation, Which are widely used in a variety of ornaments, such as furniture, accessories, door handle,architectural decoration, bathroom accessories, lighting parts, toys, tie clips, belt buckles, various metal buckle and so on,they are required a good surface treatment performance. The traditional zinc alloy die-casting material are Zamak 2,3,5,7 , the Zamk 3 is the most widely used in different industries
Zamak 3: good fluidity and mechanical properties. Used in casting of low mechanical strength, such as toys, lamps, decorations, some electrical parts.
Zamak 5: good mobility and good mechanical properties. Applied to certain requirements of the mechanical strength of castings, such as auto parts, electrical and mechanical parts, mechanical parts, electrical components.
Zamak 2: there are special requirements for mechanical properties, hardness, wear resistance, dimensional accuracy requirements of the mechanical parts
.ZA8: good flowability and dimensional stability, but less liquid. Used in die casting, small size, accuracy and mechanical strength demanding workpieces, such as electrical appliances. Superloy: the best mobility, applied to the die-casting thin-walled, large-size, high precision, complex shape of the workpiece, such as electrical components of the box.
Different zinc alloys have different physical and mechanical properties, such as die casting design provides room for choice. The same time, the choice of the zinc alloy is more important to select what kind of zinc alloy, mainly from three aspects to consider
1. Die-casting their own purposes, need to meet the performance requirements. (1) mechanical properties, tensile strength, when the material fracture resistance; Elongation, brittleness and plasticity of the measure;Hardness is the resistance of the material surface is pressed into a hard object or friction caused by plastic deformation. (2) state of the working environment: temperature, humidity, media contact with the workpiece and air tightness requirements. (3) precision: accuracy and dimensional stability can be achieved.
2. process performance: (1) casting process; (2) mechanical processes; (3) surface treatment.
3. Economic good: the cost of raw materials and production equipment requirements (including smelting equipment, die casting machine, mold, etc.), as well as production costs.
