初次思考机械化的铸造工作者应该了解型砂系统,模型装置以及维修这些因素的影响。在此论文中作者力图指明一些易犯的毛病,并从他的经验中怎样避免它们而提供有用的建议。与十年前相比,今天铸造工作者更深信自动化的高压造型。由于较好地设计了造型机,混砂机以及改进了型砂工艺,从半机械化低生产率操作到良好机械化高生产率的转变已不再是肤 For the first time, mechanized foundry workers should understand the effects of sand systems, modeling devices, and the maintenance of these factors. In this essay, the author seeks to identify some of the perpetrators and provides useful advice as to how to avoid them from his experience. Today, foundry workers are more confident in the automation of high-pressure molding than they were ten years ago. The shift from semi-mechanized, low-productivity operations to well mechanized, high productivity is no longer due to the better design of molding machines, sand mills and improved sand molding processes
