Product Details
hot chamber die-casting products is a high-precision, complex, thin-walled, high-strength, high-corrosion-resistant component that is die-cast from various aluminum alloys, magnesium alloys, zinc alloys, and other casting materials. Because the hot chamber dies casting equipment has the characteristics of high pressure, high speed, high efficiency, and high quality, it has a wide range of applications and can be used in the manufacture of automobiles, electronics, the military industry, aerospace, computers, and other fields.
Hot Chamber Die Casting Advantages
- High production efficiency: The melting furnace and die-casting equipment used in the hot chamber die-casting method are run simultaneously without reheating, and the raw material utilization rate is high, which may significantly enhance production efficiency.
- High casting surface quality: Because the molten metal pool does not come into touch with air throughout the compression process, there is no oxidation or porosity on the casting's surface, and the surface quality is excellent.
- High casting precision: Hot chamber die casting has a high casting precision, allowing it to make complicated pieces with optimal dimensional accuracy and surface polish.
- Material versatility: hot chamber die casting may employ a broader range of metal materials and make castings of various sorts and applications.
- Good manufacturing environment: Unlike traditional die-casting technologies, hot chamber die-casting does not require foundry personnel to work under high temperatures and pressure. The casting environment is reasonably steady and healthier for workers.
- cheap casting cost: Although hot chamber dies casting has an initial investment cost, the raw material utilization rate is high, and the cost of castings is generally cheap.
Processing steps of hot chamber die-casting products
- Mold design and manufacture: First, mold design and manufacture need to be carried out according to the design requirements of the product. The quality of the mold will directly affect the processing quality of the product.
- Hot chamber dies casting: The preheated aluminum alloy liquid metal is injected into the mold, and the casting is formed by high-pressure injection. The advantages of hot chamber die casting are fast speed, high production efficiency, high surface finish and high dimensional accuracy of castings.
- De-flash treatment: There are usually some defects on the surface of aluminum alloy castings, including pores, shrinkage cavities, pinholes, large grains, etc., which need to be de-flashed. The methods of flashing treatment include mechanical flashing, grinding wheel flashing, oxidation flashing, and so on.
- Machining: According to the requirements of the product, machining is carried out, mainly including turning, milling, drilling, tapping, etc.
- Surface treatment: Surface treatment of castings, including sandblasting, polishing, anodizing, electroplating, etc.
- Quality inspection: Carry out the quality inspection on the processed products, including the inspection of dimensional accuracy, appearance quality, material composition, and other aspects.
- Assembly: Assemble according to the requirements of the product, including welding, screw connection, bonding, etc.
- Packing: Pack according to the requirements of the product, which is convenient for transportation and storage.
