Analysis of the sample strip of precision shrapnel/precision shrapnel

Precise shrapnel/precision shrapnel test mold strip analysis Precision shrapnel will have various abnormal strip conditions during the establishment and proofing of the new module. We should make corresponding analysis and countermeasures for the strips in different situations. The first is a complete precision shrapnel strip. When the strip is stuck in the mold and does not move, remove the mold and check the strip. (1) Check whether there is chip jumping in the mold and the material belt is deformed. (2) Check whether there is material blocking at the knife edge, and check whether the falling material hole is large enough. (3) Whether the positions where molding or cutting should be punched out. (4) Whether the part has enough space, check whether the part itself has not enough space or the forming position is not in place. (5) Whether the blanking has burrs. (6) Whether the guide needle is pulling material. It is because the straight section of the guide pin is too long (generally one material thickness is exposed on the mold surface) and the gap between the guide pin and the round hole is small (usually 0.005-0.01MM on one side) (7) Use a microscope to see the pressure damage and mold impression Both the product and the waste belt should be seen). Because there are mold prints on the scrap tape, a scimitar of the tape will be generated, which will cause the material to be uneven. (8) Check whether there is dust or jumping chips at the chipping knife edge. (Excessive chamfering at the chipping place will cause chipping, and if it is too small, there will be dust.) After confirming through the above procedure, the abnormal point of the precision shrapnel has been identified. Under the accurate analysis of the company's excellent technical team, it can be solved quickly and effectively. Ensuring that the samples are delivered to the client during the warranty period also lays a solid foundation for later mass production.
