Operators'carelessness in Zinc head die casting operation machine operates normally Operators did not carry out self-inspection after completion, and there Operators do not operate were air holes in the in accordance with products. operating standards pe op le m ac hi ne m et ho d The operation instruction clearly stipulates that the first five dies are not allowed to be used in the later production process.

Black hose cut pipe, chamfer inside and outside corner after cutting pipe, meet the drawing and process requirements. Printing content meets drawing and process requirements Installation of the splitter assembly conforms to the drawing and process requirements. Installation with splitting body, meeting drawing and process requirements Wear wire rope to meet drawings and process requirements Size specification of riveted iron short cap meets drawing and process requirements Riveted fastening rings and plastic 3 joints meet the requirements of drawings and processes. Zinc head die casting process, not in accordance with the operating documents before the start of the Wire rope fusing, cutting and knitting process, in line with drawings and process requirements 3 Quality problem point report PPT Precision cutting process, in line with drawings and process requirements. The riveting process meets the requirements of drawings and processes. In the preGP-12 test The packing tension testing meets the process meets process, the inspection the 3 speed process and requirements parameters of requirements. of operation the testing documents. equipment of the testing 3) Confirmation of root causes machine are not adjusted Through group causality analysis, the first five mold products accordingdid not to meet the standard value because of the mold temperature. thedrop oflatest Verification statistics confirm that the root cause of the the zinc head and wire rope is that the products produced by the first parameters five molds can not be directly used in the later process production, because the equipment in the first five molds production still has (original uneven cold and heat conditions, and when the workers are engaged in the zinc head die casting operation, the products produced value isproduction according to the operation documents.The defective by the first five molds can not be directly used in the setting later process 0.5S), phenomenon of blowhole exists on the surface of zinc head of which this product. After die casting, no self-checking flow is carried out into results in the production of the next process, which results in the occurrence of defects. insufficient holding time. 3 Quality problem point report PPT 3 Determine permanent corrective measures project 1 2 Aiming at the root cause Before corrective action After corrective action The die casting group operators are not familiar with the operation instructions, and the production department has not effectively trained the relevant workers (especially the new employees) of the die casting group. The production department handles the first five die products by itself before starting the machine. For the die casting group, the production department arranges the training plan of operation documents, especially for the first five die products which can not be used in the later production process, which are placed in the special red box. The operation requirements which are rejected after confirmation by the quality department are carried out by face-to-face training and assessment
