Manufacture a aluminum radiator with Haichen die casting machine need follow five baisc steps
The following are the detailed manufacture a aluminium radiator with Haichen die casting machine steps:
1. Material selection and preparation
Select a suitable aluminum alloy material, such as a specific aluminum alloy material with composition includes 9.0%-9.4% silicon (Si), 0.5%-0.75% copper (Cu), 0.35%-0.42% magnesium (Mg), etc. This material is optimized to have good fluidity, anti-sticking and corrosion resistance.
2. Manufacture a aluminum radiator : mold design
When designing the die casting mold, you need consider the complex shape and deep cavity of the heat sink.Use Pro/E software to create a 3D model of the heat sink and design the mold cavity and core.
The mold is usually made of two hardened tool steels, one for the upper mold and the other for the lower mold. These molds need to withstand high temperatures and pressures.
3. Manufacture a aluminium radiator: die casting process
The aluminum alloy is heated to an appropriate temperature (usually 650-700°C), and then the molten metal is injected into the mold by a die casting machine.
During the die casting process, the mold need preheated to above 180°C to reduce thermal shock and improve product quality.
Injection speed and pressure need adjust according to the specific material and mold design to ensure uniform filling and good molding.
4. Cooling and demolding
In the mold, the aluminum alloy cools rapidly and solidifies. The cooling rate can be controlled by passing air through the internal channels of the mold to optimize the microstructure and mechanical properties of the product. After cooling, the casting will remove from the mold using a ejector pin.
5. Post-processing
For some complex radiator structures, subsequent processing such as cutting, grinding or spraying may require to achieve the performance requirements of the final product.
Through the above steps, high-quality aluminum radiators can be efficiently produced using a die-casting machine. This manufacturing method not only enables accurate molding of complex shapes, but also ensures high strength and corrosion resistance of the product.
