Ultra-high molecular weight polyethylene (UHMW-PE) is a kind of linear structural polyethylene with viscosity average molecular weight over 2.5 million and its extremely high relative molecular weight (the relative molecular weight of ordinary polyethylene is only 20,000 to 300,000), which endows UHMW-PE with extraordinary service performance, becoming a new thermoplastic engineering plastic with moderate price and excellent performance. It combines virtually all the benefits of plastics: impact resistance, low temperature resistance, wear resistance, impact resistance, chemical corrosion resistance, self-lubrication and so on.

Shenyang Jinbei Auto Mould Manufacturing Co., Ltd. is a specialized company engaged in the manufacture of automotive molds and automotive interior and exterior covers. The company has strong automotive mold design and manufacturing strength, as well as nearly 20 years of experience in the use of CNC equipment, deeply understand that CNC machining has become an indispensable process for mold manufacturing, and will become more and more important.
Some CNC machining equipments of the company have a long service life. Although there are strict CNC machine operating specifications and good maintenance, the loss of precision of the equipment itself is inevitable. In order to effectively control the processing quality, we regularly carry out inspection and maintenance on the numerical control equipment, master the processing precision of each equipment, strictly distinguish the use of coarse and fine processing equipment, and achieve a reasonable match of existing equipment resources. Because rough machining pursues high speed, high removal rate, and low machining accuracy, the accuracy of the equipment during roughing is the most serious. Therefore, we will use the equipment with the longest accuracy and the worst accuracy. Roughing equipment, new equipment and precision equipment are designated as finishing equipment, which can effectively control the impact of machine tool loss on the processing quality and indirectly extend the service life of the equipment.
Powerful software can improve the quality and efficiency of mold processing. We also need CNC programmers who are proficient in software functions. They must also have extensive on-site machining experience and theoretical knowledge. There are also machine operators who are the executors of CNC machining, and their various operations have the most direct impact on CNC machining. Because talent is the decisive factor in CNC machining, it plays a key role in the quality and efficiency of CNC machining. Recently, a mold company owned by BMW Motors of Germany came to visit and visit our company, and a simple technical exchange was held at a later forum. In the process, we learned the advanced features of the world's leading mold companies, and also saw the gap between us. Their CNC machining process is to arrange multiple CNC equipment into lines, and the blanks are processed in sequence, CNC laser quenching, three-coordinate detection, and finished products. There is no special case and no further CNC machining is required. In the introduction they also emphasized that their CNC program designers and machine operators are served by one person, namely “CNC Engineerâ€. The numerical control engineer is responsible for the whole process of his own numerical control equipment and the machining parts on the equipment, so that the quality of CNC machining can be better controlled. Of course, the realization of this process is inseparable from the close cooperation of other functional departments, and it also reflects the rigor of enterprise management, the soundness of rules and regulations, and the high degree of coordination of the spirit of collaboration. Compared with such a company, we still have a long way to go, and there are still many things worth considering. Although the gap is great, we should not care too much about this gap, because today is our tomorrow, and good things are ahead.
