PRODUCT PARAMETERS

Material ADC-12, A380,
Process High Pressure Casting
Tolerance of blank ISO8062-CT6
The depth of the product is 220mm, which is relatively deep compared to the diameter of 190mm. Considering the die-casting full molding process and the need to take into account the cost. Because the larger the model die casting out of the product quality is higher, but at the same time the cost is also higher.

We can choose 800T, 600T, 500T die-casting machine to complete this product, but for cost considerations, we chose 500T die-casting machine. Debugging the parameters of the pressure injection, need to ensure the perfect filling of the remote product.

The high-pressure casting process itself is very easy to appear in the product internal subcutaneous porosity, especially in the 0.5mm below. This product is 220mm deep, need to process the position of the maximum depth of 180mm, the inner cavity of the mold pulling slope is too small will lead to the product out of the mold is not smooth, resulting in product strain, pulling the mold slope is too large will lead to the inner cavity processing volume increases, which will lead to the processing of the surface of the air holes. For this reason, we carried out a software simulation casting in the mold design stage to find an optimal balance between the processing volume and the mold exit slope. An optimal mold pull-out slope was finally obtained.

In the die casting process, through the debugging of injection parameters, to ensure that the product intact mold filling. In the later machining process, no defects such as porosity appeared on the machined surface.

Performance

High molding efficiency: high-pressure die casting can be under high pressure to liquid metal fast filling mold cavity, filling speed is about 0.5-120m/s, filling time is only 0.01-0.2 seconds, which makes the production efficiency is high, easy to realize mechanization and automation.
Castings of high quality: high-pressure die-casting can solidify under pressure, forming high-strength, high-precision castings. The casting size tolerance grade can reach CT3 ~ CT6, surface roughness is generally Ra0.8 ~ 3.2μm, with better surface quality and dimensional accuracy.
Compact structure, high strength: high-pressure die castings have compact structure, high strength and excellent pressure and wear resistance. Aluminum alloy die castings have excellent corrosion resistance and uniform density, and can withstand high pressure and wear2.

Advantage

High production efficiency: high-pressure die casting casting process can complete the molding of the motor shell in one go, avoiding the traditional welding and machining process, saving the cost of manpower and time, and greatly improving the production efficiency.
Excellent product quality: high-pressure die-casting casting process can ensure that the motor shell size is accurate, smooth surface, high density, no porosity and slag and other defects, improve the overall quality and reliability of the product.
Material saving: high pressure die casting casting process can reduce the waste of raw materials, because the metal material is extruded and molded under high pressure, unlike the traditional cutting and forging process, it can effectively reduce the material loss.
Molding high degree of freedom: the use of high-pressure die-casting casting process can produce a complex shape, structure of the motor shell, to meet the needs of different customers, improve the flexibility of product design and production adaptability.

Environmental protection and energy saving: high-pressure die-casting casting process does not need to use glue and other adhesives, reducing the emission of harmful gases, and can recycle metal materials, reducing energy consumption and environmental pollution.

Operation scenario

High pressure die casting casting process is widely used in the production of motor shell. In electric vehicles, industrial motors and other fields, high-pressure die casting casting process is widely used in the manufacture of motor shells to meet the high demand for product quality and efficiency.
