Inspection methods and standards for metal stamping parts

The market competition is fierce, so the market has higher requirements for the appearance quality of Metal Stamping parts, which makes them more competitive. During the production process of stamping parts, some quality problems are inevitable, and stamping parts manufacturers only leave the factory after the product is inspected and qualified. So how to preliminarily determine whether the metal stamping parts are qualified?

Firstly, from the appearance of the product, qualified stamped parts processing products use high-quality metal or non-metal sheet materials, and secondly, do not damage the surface of the raw materials during the stamping process, so the appearance of the product is smooth and beautiful, which also provides favorable conditions for secondary processing of the product (painting, electroplating, phosphating). The surface quality judgment methods for general stamping parts are divided into visual inspection and touch inspection. Visual inspection: No cracks, necking, pitting, deformation, material defects, wrinkling, stacking, or other obvious material defects. Touch: No obvious burrs, indentations, scratches, rough corners, etc.

The processed product of a qualified stamping part has high dimensional accuracy, the uniform error of the product produced by the unified mold is very small, and the size and weight error of the defective product is large.

There are many follow-up inspections, such as touch inspection, oilstone polishing, flexible mesh polishing, oiling inspection, visual inspection, and gauge testing. The specific choice of method depends on the actual needs of the stamped product.
