How to inspect the metal stamping parts when the manufacturer receives materials?

For each batch of incoming materials, the manufacturer should check whether the color, shape, material number, version, material, etc. of the material belt and metal stamping parts conform to the requirements of the drawing or model; each batch of incoming materials should check the 'shipment inspection' of the material belt and metal stamping parts. Whether the report' is filled in correctly and complete, and whether the final quality judgment is qualified; according to the sampling plan, each batch of incoming materials will be sampled to check whether the material belt and metal stamping parts are deformed, missing plating, pitting, rust, burrs, piercing, and less Positioning holes, multiple positioning holes, dirty and other bad phenomena; each batch of hardware stamping parts should be randomly selected 5PCS samples, assembled with a conformable counterpart, and checking whether the hardware stamping parts are assembled badly; find out the corresponding drawings Or sample, prepare calipers, projectors and other measuring tools, randomly select 5PCS samples and 5 points from the material tape for each batch of metal stamping parts, use the caliper or projector to measure the key dimensions indicated in the drawing, as well as the material tape and metal stamping The thickness of the part and the test data are recorded. For the hard-to-measure test assembly size of the metal stamping parts, the actual configuration can be the main thing, or it will not affect the assembly; each batch of incoming materials simulates the actual assembly of the pressing tape and the metal stamping parts, and check whether there is any breakage Unfavorable phenomena; reliable inspection; 1. salt spray test 2. tinned surface welding test 3. elasticity test of shrapnel (not for material strips); after each batch of incoming materials, the supplier needs to provide a film thickness test report, and the test data needs to meet Drawing specification requirements; RoHS test; According to the requirements of 'IQC Inspection GuideThere is no mixing, check the carton and packaging for damage, dampness and other bad phenomena, check whether there is any change of logo, etc.; recommended article: the technological characteristics of titanium stamping parts processing Previous article: stamping parts processing factory talk about the three views of stamping dies
