Benefits of Zinc Die Casting

When you are going to die casting, there will be a variety of material choices. If we suggest that you choose zinc die casting, you will doubt why to use zinc die casting. 

Here are a few reasons why zinc die casting should be chosen.

1. Zinc die casting parts have good quality.

1) High dimensional accuracy. It generally can reach to level IT11-IT13, sometimes even as high as IT9.

2) Good brightness. Surface roughness can reach to ra0.8-3.2 um, sometimes even up to ra0.4um.

3) Zinc die casting has dense organization and much higher strength and hardness. Because the liquid metal is cooled and solidified under pressure, and the filling time is extremely short, the cooling speed is extremely fast. Therefore, a layer of metal grains close to the surface of the die casting is fine and dense, which not only makes the surface of the casting have good wear resistance and corrosion resistance, but also improves the hardness of the whole casting. The tensile strength of the zinc alloy die casting is generally 25 to 30% higher than that of sand casting, but the elongation rate decreases.

4) Stable dimensions and good interchangeability of products.

5) It can make metal parts that are intricate, well-defined, thin walls, because the molten metal is high pressure to keep the flow high, so that you can get other metal parts that are difficult to process. For example, the minimum wall thickness of the current zinc alloy die casting parts can reach 0.3mm, the aluminum alloy casting can reach 0.5mm, the minimum diameter of the casting is 0.7mm, and the minimum pitch is 0.75mm.

2. High production efficiency.

1) The machine productivity is high, for example, domestic JIII3 horizontal cold chamber die casting machine has an average of 8-hour die-casting of 600-700 times, and the small hot chamber die casting machine can cast an average of 3,000 to 7,000 times per eight hours.

2) Die casting has a long-life die, which can reach up to 60-80 thousand times, sometimes up to 100,000 times.

3) Easy to realize mechanization and automation.

3. Excellent economic effect

1) High material utilization. Due to the die casting with dimension precision, low surface roughness value, so they generally do not need to undertake machining and can directly use the assembly, or processing capacity is very small, only need a small amount of mechanical processing to use assembly, so not only can improve the utilization of metal, and can reduce a lot of processing equipment and working hours. Its material utilization rate is about 60-80%, and the blank utilization rate is about 90%.

2) The cost of zinc die casting is relatively cheap.

3) The parts of other materials can be directly embedded in the zinc alloy die casting, so as to save precious materials and working hours, so as to meet the requirements of use, expand the product use, and reduce the assembly work, so that the manufacturing process can be simplified.

Zinc die casting is widely used in many industries, including zinc alloy die casting. As the zinc alloy die casting can include many different materials, so you can according to your own need to select suitable materials.
