广东佛山市的薄壳泥型铸造法,不仅国外没有,就是国内也极少见。在过去,由于我国机械工业不发达,没有引起注意,所见没有得到应有的发展。这种方法比起砂型铸造具有许多独特的优点,特别适宜于小型铸件的大量生产。用这种方法铸出的铸件一般不需经过加工,尺寸精确度一般可达6—7级,表面光洁度可达(?)3—(?)(?)4。由于各种分析仪器和时间不足,尚不能对各种材料作详细的化学分析,这里仅作一般性的介绍。 Foshan, Guangdong thin-shell mud casting method, not only abroad, is rare in China. In the past, due to the underdevelopment of China’s machinery industry, it failed to attract any attention and saw no progress. This method has many unique advantages over sand casting and is particularly suitable for mass production of small castings. Castings cast in this way generally do not need to be processed, the size of the general accuracy of up to 6-7, the surface finish up (?) 3 - (?) (?) 4. Due to the lack of various analytical instruments and time, detailed chemical analysis of various materials is not yet possible and this is only a general introduction.
