Reasons and solutions for scraps of metal sensor housing stretched parts

The metal sensor housing drawing part is completed by drawing, stamping and other processes to obtain the required workpiece. There are a lot of waste products during production. Why is this?

The reasons that lead to the occurrence of scraps of metal sensor housing stretched parts are that the quality of the stamping materials used is not good. The installation, adjustment and use of the stretching die are incorrect; the staff did not place the strips accurately and did not feed the strips according to a certain gap. The mold life cycle is too long, resulting in gaps in the mold parts or wear of the guide parts. The stretching mold has been subjected to shock and vibration for a long time, which loosened the fasteners and caused other changes in the position of the mold assembly. The staff's carelessness did not follow the standard operation procedures.

Measures to prevent waste products from the tensile parts of the metal sensor housing: the purchase of raw materials must meet the relevant quality inspection conditions, and the dimensional accuracy and surface quality of the raw materials shall be inspected by laboratory tests. It is necessary to strictly abide by the regulations of various links in the work process. It is necessary to ensure that the equipment used can operate under normal conditions.

Before the mass production of the workpiece, the first piece must be inspected, and the mass production step can only be started after the inspection is qualified. It is also necessary to strengthen the inspection to find the existence of the problem in time. Comply with safety production rules and regulations. The last point is to ensure that the mold cavity is clean during the processing, and the working place must be organized and follow the 5s standard.
