采用消失模工艺生产薄壁壳体铸件最典型的就是球墨铸铁管件的生产,常因泡沫模样易变形而导致铸件尺寸超差和实圆变形;结合我们在生产中实践,介绍了防止泡沫模样变形和减轻铸件失圆变形的几项措施:如从模具组装、成型工艺和外加辅助手段方面进行控制,有效地减轻管件的变形缺陷
The use of EPC technology to produce thin-walled shell castings is the most typical is the production of ductile iron pipe fittings, often due to deformation of the foam easily lead to oversize casting and round real deformation; combined with our practice in production, introduced to prevent foam deformation And to reduce the castings out of shape deformation of several measures: such as from the mold assembly, molding technology and additional means of control, effectively reduce the deformation of the tube defects
