Aluminum Casting Parts refer to the process of pouring molten aluminum or aluminum alloy into a mold through a casting process, and then cooling and solidifying to form aluminum parts of the required shape and size. Cast aluminum valve bodies have the characteristics of light weight, corrosion resistance, good thermal conductivity and strong machinability, and are suitable for a variety of industrial fields.
Losier Technology Development Co., Ltd. is a manufacturer and supplier of high-quality confidential casting cast aluminum.
Aluminum Casting Parts are formed by pouring molten aluminum or aluminum alloy into a mold through a casting process, and then cooling and solidifying to form aluminum parts of the required shape and size. Sand molds or metal molds are usually used for casting. Commonly used aluminum casting methods include sand casting, die casting, low-pressure casting and precision casting.
The production process of aluminum casting parts includes mold design and production, smelting and pouring, cooling and solidification, cleaning and inspection. Aluminum Casting Parts have the characteristics of low cost, high production efficiency, flexible design and excellent performance. They are widely used in many fields, including valve industry, medical equipment, automotive parts, power equipment, wind power equipment, injection molding machines and other fields.

Mold design and production: Design the mold according to the product drawings, and select the appropriate material to make the mold. The precision and quality of the mold directly affect the quality of the casting.
Smelting and pouring: Heat the aluminum or aluminum alloy material to a molten state and inject it into the mold by gravity or external force. During the pouring process, the pouring temperature and speed need to be controlled to avoid defects in the casting.
Cooling and solidification: Wait for the aluminum liquid to cool and solidify in the mold to form a casting. The cooling speed and method will affect the structure and performance of the casting.
Cleaning and inspection: Clean the defects such as sand and burrs on the surface of the casting, and conduct quality inspection to ensure that the casting meets the standard requirements.
Oxidation slag inclusions: mostly distributed on the upper surface of the casting, with a grayish white or yellow fracture. Prevention methods include using clean furnace charge, improving the design of the pouring system, and using appropriate flux to remove slag.
Porosity: generally round or oval, surface pores can be found by sandblasting, and internal pores can be found by X-ray fluoroscopy. Prevention methods include correctly controlling the pouring speed and improving the exhaust capacity of the sand mold.
Shrinkage: generally occurs around the inner runner and in thick and large parts. Prevention methods include improving the design of the pouring system, correctly selecting and handling cold iron, etc.
