随着工业的发展,压铸工艺在铸造生产中的比重愈来愈大,我厂生产的铝铸件有60％以上系采用压铸工艺方法生产的。压铸模是压铸生产中必不可少的重要工艺装备,它直接影响着压铸件的生产周期、质量和成本,压铸模的制造精度要求高、加工难度大、制造周期长、材料贵重、造价较高,因此 With the development of industry, the proportion of die-casting process in casting production is getting bigger and bigger. Over 60% of the aluminum castings produced by our factory are produced by the die-casting process. Die-casting mold is an essential technology in the production of die-casting equipment, it has a direct impact on the die-casting production cycle, quality and cost, high precision die-casting mold manufacturing, processing difficult, long manufacturing cycle, expensive materials, high cost ,therefore
