How Dongguan precision castings are chemically cleaned
Dongguan precision castings have the function of being rust-free. It can be seen from its production process that Dongguan precision castings only require pure stainless steel liquid casting, and castings produced through a series of processes can produce castings.
The shot peening method used in Dongguan precision castings is divided into shot peening and sand blasting. Shot peening is used for surface treatment, which has strong impact and obvious cleaning effect. However, shot peening of thin plate workpieces can easily deform the workpiece, and shot peening will cause the metal matrix on the surface of the casting to Deformation. Therefore, for castings with oil, shot blasting cannot remove oil stains. Among existing workpiece surface treatment methods, sandblasting cleaning also has a good effect. There are higher requirements for cleaning the surface of castings.
In addition, the polishing method is that the brush roller is driven by a motor, and the brush roller rotates in reverse and at high speed on the upper and lower surfaces of the plate belt to remove iron oxide scale. The iron oxide is washed away with a closed-circulation cooling water flushing system. Dongguan precision castings are cleaned by centrifugal force shot blasting. , Dongguan precision casting shot blasting and rust removal.
Secondly, when choosing Dongguan precision castings and dust removal equipment for the sandblasting process, you must fully consider the actual production conditions and try to choose equipment with greater power relative to the production requirements. Since shot blasting equipment generally wears out quickly, long-term use will affect Dongguan precision castings are produced, so choosing equipment with higher power will greatly reduce future maintenance costs.
