Copper castings are a kind of common metal parts, usually used in mechanical equipment, automobile parts, ship parts and other fields. Copper castings have good thermal conductivity, electrical conductivity, corrosion resistance and mechanical properties, so they are widely used in various industrial fields.

The manufacturing process of copper castings mainly includes model design, mold manufacturing, fusion casting, cleaning and surface treatment. First of all, according to the requirements of the parts for the model design, to determine the shape, size and material of the parts. Then manufacture the mold, put the mold into the furnace, heat it to above the melting point of copper, then inject the molten copper liquid into the mold, and take out the copper casting after cooling. Finally, cleaning and surface treatment are carried out to make the copper castings reach the surface quality and precision required by customers.

There are many advantages of copper castings. Firstly, copper castings have good thermal and electrical conductivity, which can be used to manufacture high frequency circuit boards, radiators and other electrical parts. Secondly, copper castings are corrosion-resistant and have good plasticity, easy to process into a variety of complex shapes. In addition, the surface finish of copper castings is high, the color is golden, with a good decorative effect, suitable for high-end products.

However, copper castings also have some disadvantages. First of all, the cost of copper castings is high, the manufacturing process is complicated, and more equipment and processes are required. Secondly, the density of copper castings is relatively large, heavy weight, not suitable for the requirements of lightweight product manufacturing. In addition, the weldability and strength of copper castings are not as good as other metal materials.

Overall, copper casting is a kind of metal parts with a wide range of application prospects, and has an important position in the field of industrial manufacturing. With the continuous development and progress of technology, the manufacturing process and quality of copper castings will be further improved to provide better quality parts and components for various industries.
