我厂是生产眼科医疗器械的厂。近年来为解决生产光学诊察器械加工量大、金加工能力不足的困难,决定改革生产工艺,采用压铸新工艺从根本解决问题。压铸工艺是具有成型复杂、铸件尺寸精度高、表面光洁度高、生产效率高等特点的少或无切削的新工艺。采用这种工艺首先需要对压铸模设计、制造、压铸操作、合金熔 I plant is the production of ophthalmic medical equipment factory. In recent years to solve the production of optical inspection equipment processing large, insufficient processing capacity of gold difficulties, decided to reform the production process, the use of new die-casting process to fundamentally solve the problem. The die-casting process is a new process with less or no cutting with the features of complex molding, high dimensional accuracy of castings, high surface finish and high production efficiency. The first use of this process requires the die-casting mold design, manufacture, die-casting operation, the alloy melt
