During the cleaning process of Dongguan Precision Casting, the surface of its products is not allowed to have oxide scale and sticky sand to affect the processing of its parts. The inner cavity of the product is free of any residual sand during the processing. Defects such as core block, burr, flash and so on.

The geometry of stainless steel casting is complete in the process of processing, and the sand removal damage on the surface that does not need to be processed should not be greater than the dimensional deviation of the place, regardless of the material of the casting, the residual root of the remaining riser needs Except in time.

The processing surface of the stainless steel casting is not allowed to have the residual amount of the pouring riser. When the product is repaired, the processing surface can use a grinding wheel or other tools. During the repair process, the weld must be repaired and flattened according to the parent body, and then Clean up the splashed casting welding slag.

After the shot blasting of Dongguan precision castings, the products are effectively processed without magnification. The code of the workpiece in the product should not be able to see the dirt and oxide scale. The surface of the product should be uniform and the color should be metal. of.

During the production process of stainless steel casting, some hardware facilities and management problems will cause its deformation. The product needs to find the mold preset before wax injection until the mold temperature is the same as the room temperature of the wax injection chamber. Start waxing.

After the finished product of stainless steel casting comes out, self-inspection is first required. During the self-inspection, it is mainly to see whether the product is deformed or defective during processing. It is recommended to use jig inspection as far as possible after the finished product is shipped. , This can effectively detect its accuracy and speed.

For precision cast steel processing, hard materials can be used. During use, the surface of the product must be wear-resistant. For some parts with a relatively large area, the tonnage of the press must be calculated reasonably, so that it can effectively avoid Its waste and insufficient power.
