Chang Chai foundry is about to break through the bottleneck of 4G33V16 production, and the production capacity has been improved

Since October this year, 4G33V16 diesel engine market continued good sales situation, to meet the market demand, the company requires foundry in addition to the normal monthly delivery before the end of the year, an ample supply of finished goods inventory.

Through a comprehensive analysis of the foundry, it is found that the low production capacity of water jacket core is the bottleneck problem affecting production capacity. In order to solve the bottleneck problems in production, the successful completion of the production tasks, Ningbo die factory decided to entrust a new Polytron Technologies Inc to develop water jacket core hot core box, and commissioned Sanxin Machine Manufacturing Co. Ltd. is a hot core shooting machine.

At the beginning of December, core shooting machine and core box to complete delivery and complete the installation and debugging of normal equipment box. After the debugging, the core box is tested and the sand core is finished without defects. In order to ensure the correctness of the new sand core on the one hand, the new and old jacket core pictures compared using the 3DSS Blu ray 3D optical scanner is the purchase of new, new water jacket core and sand core 3D comparison; on the other hand, the factory will arrange 4G33V16 body test mode, test mode after casting processing machine processing factory verification. To be qualified after the processing of batch production, then, 4G33V16 body capacity will increase to twelve thousand. In addition, the matching tooling, such as sand core transfer frame, core center brush plate, etc., have been completed and put into use.

4G33V16 diesel engine is the focus of the company's products, foundry on very seriously, the leading factory in the protection of production at the same time, but also to grasp the quality of the work, make great efforts to reduce the casting scrap rate. In September October, machine processing factory feedback slag and sandinclusion increased slightly, the timely convening of foundry analysis, a comprehensive analysis of the causes of the defects, through various measures to improve the core integrity, improve the gating system, increase filter, purifying molten iron slag and so reduce the sand core defect, slag and will sandinclusion from 4.3% to 1.62%, effectively improve the slag and sand hole. The next stage, the competent technicians will continue to work hard, and strive to further reduce the slag and sand hole, and the total rejection rate, to reduce the loss as much as possible.
