?The domestic development trend of gravity casting molds is improving
Time:2023/6/1

With the rapid development of domestic mold work, there are no fewer than hundreds of gravity casting mold manufacturers. With the development of the manufacturing industry and the influx of foreign investment, mold manufacturers have accumulated their planning and technical strength over time. With the widespread use of CNC processing equipment, the processing level of aluminum alloy gravity casting mold work is no longer much different from that of foreign countries, and many mold factories also have more advanced testing equipment, But our management level, planning concept, and business philosophy still fall behind our foreign counterparts, and our mold materials and heat treatment strengthening techniques also lag behind developed countries. Regarding the current situation of casting mold manufacturers, there is a shortage of engineering skilled personnel who have practical experience and understand both mold making and casting processes. Mold debugging and process validation are also necessary obstacles in the mold production process, as obtaining successful molds and mature processes is what many casting factories with relatively weak technical strength expect today

The standardization of molds and the use of mold standard parts are the development trends in the mold industry. Gravity casting molds are even more so for those who started later. As long as the standardization of molds is implemented, it is possible to standardize the behavior of mold manufacturers and promote the supply of high-quality, affordable, and compliant molds by mold factories. At the same time, the standardization of molds and the use of mold standard parts will make it easier for foundries to monitor mold quality, and also make mold protection and maintenance more convenient. The use of standard parts in molds and the production planning effect will help to modify the current situation of multiple varieties, small batches, and low production power in mold work, which is conducive to reducing costs and improving production rates
