Copper Cast from Sand
Benefits:
Cost-effective for large production volumes
Possibility to produce large and complex shapes
Good surface finish and dimensional accuracy
Suitable for various copper alloys
Disadvantages:
Lower dimensional accuracy compared to other casting methods
Longer production time due to the mold making process
Limited to alloys with low melting point
May require additional machining after casting
Description of the sand mold casting process for the production of copper parts:
Making the part: A template or replica of the final part is created from wood, metal or plastic.
Making the mold: The template is placed in a box of sand and then removed, leaving a cavity representing the final shape of the part.
Metal preparation: Copper is melted in a furnace at high temperatures until it becomes a liquid.
Pouring: The molten copper is poured into the cavity of the mold, filling the space left by the pattern.
Cooling: The copper solidifies in the mold as it cools.
Extraction: After cooling, the sand mold is broken or shaken out, exposing the solidified copper part.
Finishing: The part may be subjected to additional finishing processes such as grinding, machining or polishing to achieve the desired final shape and surface quality.
This process produces a wide range of copper parts and components used in a variety of industries.
We have long-term cooperation with many copper casting manufacturers. And all of them have been tested and approved according to ISO9001:2015 system. With their more than 20 years manufacturing experience, I believe that all the products we produce will perfectly meet your requirements under our strict quality control.
