How do precision metal processing manufacturers inspect the quality of metal stamping parts

Stamping is one of the more processing methods used by precision metal processing manufacturers. Metal stamping parts refer to molds for steel or non-ferrous metal plates at room temperature. The press provides the pressure required for processing and is formed into a specified shape. So how do precision metal processing manufacturers inspect the quality of metal stamping parts? The following precision metal processing manufacturers will share with you.

　　 For metal stamping processing, first of all, precision metal processing manufacturers must control the quality of raw materials. The inspection period can be divided into material acceptance and material cleaning, inspection before production and after material. Next, the forming stamping parts can be inspected by the following inspection methods.



　　 One can wipe the surface of the outer cover with a clean gauze. The inspector needs to wear touch gloves to touch the surface of the stamping part along the longitudinal direction of the stamping part. This inspection method depends on the experience of the inspector of the precision metal processing factory. If necessary, oilstone can be used to polish the detected suspicious area and verify it, but this method can be regarded as an effective quick inspection method.

　　 Second, you can wipe the surface of the outer cover with a clean gauze. Then use a clean brush to apply oil evenly to the entire outer surface of the stamping in the same direction. Put the oiled stamping parts under strong light for inspection. The precision metal processing manufacturer recommends that the stamping parts be erected on the car body. This method can easily find tiny pits, pits, and ripples on the stamping parts.
