Dongguan precision castings are closely related to daily life. For example, the frequently used handles, anti-theft locks, heating plates, upper sewage pipes, frying pans, gas stove racks, electric irons, etc., are all copper castings. Among them, general sand mold castings are widely used, accounting for about 80% of all castings production.

The giant copper castings of Dongguan precision castings can be divided into cast copper tiles and forged copper tiles. The interior is cooled by water, and the exterior is equipped with related parts that cooperate with the conductor tube and the fixed ring.

Copper ring refers to the all-copper or alloy copper machine equipment components obtained by the production and processing method of casting. In the casting of copper castings, the metal material type casting method is used to accelerate the condensation of aluminum alloy, which has a key function in improving the quality of copper castings and avoiding casting problems.

The net weight of giant copper castings accounts for a very large proportion. Many parts and key components are all made of castings and are closely related to the quality and accuracy of the machine tool. The quality of machine tool castings is of great significance to the quality, service life and precise maintenance of the machine tool.

During the production and processing of copper castings, attention must be paid to details and failures. We must not ignore the environmental pollution problems. We must ensure that the natural environment meets the regulations, otherwise it will endanger the quality of production and processing. The metal material is smelted into a liquid that meets certain regulations and poured into a metal mold. After the condensation is formed and cleaned, the processing process to obtain a casting with the expected appearance, specifications and characteristics is casting.

In addition, low-pressure casting methods can also be used for giant copper castings to increase the relative density of aluminum alloys and avoid impurities caused by castings during the pouring process. Some alloy copper can also be cast by working pressure, which is convenient for obtaining high-quality copper castings.
