How to inspect stamping raw materials and stamping parts

When the stamping processing plant receives the raw materials and stamping parts, they need to inspect their quality to ensure the smooth production and use. Precision-Committed to the production of precision stamping parts for more than 10 years, we can provide precision stamping parts solutions for various industries. Next, Precision will introduce how to inspect stamping raw materials and stamping parts. The manufacturer shall check the color, appearance, material number, version number, material, etc. of the material belt and precision stamping parts for each batch of incoming materials, and check whether the material belt and precision stamping parts conform to the requirements of the engineering drawings; Check whether the Shipping Inspection Report is properly filled in, and then the quality is judged whether it meets the standard; According to the sampling plan, each batch of incoming materials will be sampled to inspect the material strips and precision stampings for deformation, missing plating, black spots, rust, burrs, and drape. Hidden hazards such as sharp edges, fewer positioning holes, more positioning holes, stains, etc.; each batch of precision stamping parts should be randomly selected 5 samples, assembled with compatible objects, and check whether the precision stamping parts have assembly hazards; find Matching engineering drawings or samples, prepare measuring instruments such as vernier calipers, projectors, etc. Each batch of precision stampings will randomly select 5 samples and 5 points from the material tape, and use vernier calipers or projectors to accurately measure the items in the engineering drawings. The marked key specifications, and the thickness of the material strips and precision stamping parts are recorded and the data is tested. For the trial specifications that are difficult to accurately measure the precision stamping parts, the actual configuration can be the leading factor, or it will not affect the assembly; simulation simulation of each batch of incoming materials Specific installation of stripping belts and precision stamping parts to check whether there are hidden dangers of cracking; Inspection method; 1. Salt spray test 2. Electroplating tin surface welding welding inspection 3. Spring sheet elasticity inspection (not for material belt); Each batch of incoming materials After that, the distributor needs to show the film thickness test report, and the data test needs to comply with the specifications and models of the engineering drawings; RoHS test: According to the 'IQC Inspection GuideAfter the incoming materials, check the packaging; check whether the current product ticket is filled in in detail and appropriate, check whether there are any wrong materials, check whether the carton and packaging are damaged, moisture and other hidden dangers, check whether there are any signs of change, etc.; A hole with a lot of curling and torn edges is produced, which makes the model slightly highlighted by a thin edge. A small gap produces a slight curling and tearing of the large viewing angle, causing the model to be more or less vertical and the surface of the raw material; an idealized waste needs to have an effective collapse angle and a well-proportioned bright band, so that the impact can be maintained. The working pressure is small and a clean and tidy round hole with very few burrs is produced. From this point of view, the expansion of the gap to increase the service life of the mold is obtained by abandoning the quality of the finished product hole; [Related recommendation] Learn more: Polished stainless steel surface What are the methods?
