树脂砂用木模的设计与制作

The Design and Making of Wood Model for Gummy Sand

树脂砂造型能够获得表面平整 ,棱角清晰 ,尺寸精度高的优质铸件 ,首先取决于木模的质量 ,木模的好坏是优质产品的基础 ,我厂从九九年五月开始采用树脂砂工艺生产复杂系数较高的铸件 ,所使用的木模无论在结构上 ,还是在工艺参数上都与粘土砂铸造用木模有很多不同 ,我厂在两年的生产过程中积累了许多经验。

Good casting with smooth surface,clear edges,higher precision using gummy samd mosthy depends on the quality of wood model.The wood models applied in our factory to produce high complexation coefficient casting using gummy sand have much difference with clay sand foundry not only in structure but process parameters.
