How to control the quality of precision mold manufacturing?

by:NJPE     2020-02-08
The reason why NJPE is the leader in the field of precision molds is that it has a very systematic and perfect quality management system for quality control of precision mold manufacturing (IQC), Process product inspection (IPQC), Molding product inspection (FQC), Mold shipment acceptance (OQC) Quality control is carried out in the four major links to ensure the processing quality of precision molds. NJPE can achieve an average pass rate of 90% for the first Mold test. How did it happen? Let me reveal the secret for you! For every precision mould manufacturing order, it is far from enough to only attach importance to the processing and testing links. From the signing of the order to the delivery of precision moulds to customers, every small link is likely to affect the quality of the mold. There must be an independent engineering quality control system to ensure the quality of the customer's products. Therefore, NJPE can do it. From the whole processing process, in order to achieve the precision of the precision mold specified by the customer, special care should be taken in every processing process. After the R & D personnel design and shape the precision mold, it officially enters the processing stage, and there are several operations in the whole processing process: 1. Blank preparation; 2. Rough machining; 3, semi-finishing-Heat treatment (Quenching, quenching); 4. Precision grinding; 5, electrical processing; 6, fitter repair. It is particularly important to select suitable materials before precision mold processing. According to the customer's requirements for the service life and performance of the mold, appropriate steel should be selected, and the working strength and stress capacity of the precision mold should be estimated. In precision mold grinding, it is necessary to select appropriate grinding wheel, feed quantity and workpiece clamping to effectively control grinding deformation, grinding cracks and the occurrence degree of microcracks. In EDM control, the adjustment of cutting machine tool, the design of machining route and the selection of EDM process are especially important. The precision mold after processing also needs surface treatment, generally including polishing, grinding and polishing (Fitter) These processes ensure that the surface of the precision mold is like a mirror. Finally, enter the mold assembly work, under the guidance of the structure and technical requirements of the precision mold assembly drawing, assemble and combine according to the correct assembly order. Such a set of high-quality precision molds are produced. After the mold is opened and closed, the mold can be packaged and delivered to the customer after checking whether the mold action is accurate and reliable.
