Zinc Alloy Die Castings

Zinc alloy die castings parts are widely used in Automotive, lamp shade power tools, household appliances and various accessories.

The features of Zinc alloy die castings are as follows:

1). High Density;
2)Good Casting performance, complex shapes can be die-casting, precision parts, thin-walled castings smooth surface.
3). Good surface after finish surface finished, such as: chrome plated, spray, spray paint.
4) Melting and die-casting iron absorption, pressure-type non-corrosive, non-stick mold.
5) has good mechanical properties at room temperature and abrasion resistance.
6)Low melting point, melting at 385°C easily die casting.

More about Zinc Alloy Die Castings

Zinc Alloy Die Castings 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 Zamak 3 is the most widely used in different industries,

Zamak 3: Zinc Alloy Die Casting have a good fluidity and mechanical properties. Used in casting of low mechanical strength, such as toys, lamps, decorations, some electrical parts.

Zamak 5: Zinc Alloy Die Casting have a 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: Zinc Alloy Die Casting have a there are special requirements for mechanical properties, hardness, wear resistance, dimensional accuracy requirements of the mechanical parts

ZA8: Zinc Alloy Die Casting have a 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,Zinc Alloy Die Castings have 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 of Zinc Alloy Die Castings:
(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.
