How to check whether there are defects in precision stamping parts? 【Hardware】

Precision stamping parts are high-precision stamping parts, which may be just a small part that cannot be smaller, but it has a great impact on the overall quality of the product. Therefore, the quality requirements of precision stamping parts are relatively high. Then the defect inspection of precision stamping parts is indispensable. Inspection methods and standards for precision stamping parts defects: 1. Inspection methods for material defects: visual standards, material strength does not meet the requirements, traces left by rolled steel, overlaps, orange peel, streaks, loose galvanized surface, and galvanized layer peeling . 2. Inspection method for irregular rounded corners: visual inspection and inspection tool measurement of rounded corner radius is not even enough, not clear and smooth enough. Outer cover parts are not allowed. The irregular rounded corners of some assembly surfaces and lap surfaces of the inner cover parts not only affect the appearance of precision stamping parts, but also affect welding and assembly seriously. 3. Inspection method for pit bags: visual inspection. The existence of pits seriously affects the appearance quality of the covering parts after painting, which is a defect that customers cannot tolerate. Large-area pits will also affect the strength and fatigue of precision stamping parts, and cannot be used. 4. Wrinkle investigation method: visually, the outer cover is not allowed to have any wrinkles that are easily noticeable by the customer, and the inner cover is not allowed to have serious wrinkles that may cause material overlap. The above is part of the troubleshooting methods of precision stamping parts. If you have a need in this area or want to know more, please add V: understand
