The key steps in the manufacture and inspection of copper castings mainly include the following parts:
Key steps in manufacturing
Raw material preparation and smelting: Chemical composition analysis of raw materials, weighing according to the proportion after passing the test and adding them to the furnace for smelting.
Pre-casting testing and centrifugal casting: Sampling and testing after preliminary slag cleaning, adding elements according to customer needs, and then centrifugal casting.
Subsequent processing: The cast castings are subjected to lathe processing, boring, sandblasting and other processes to make finished products.
Key steps in inspection
Surface quality inspection: UT test, salt spray test, UV resistance test, etc.
Shape and size specification inspection: Flatness, parallelism, straightness and other inspections are carried out according to the purpose of the casting.
