使用特殊工艺将陶瓷型厚度控制在２～３ｍｍ内，其外村套采用石墨或金属型，可有效地减少和限制脱碳层的产生，同时，薄壁陶瓷型还大大地减少铸型脱液收缩和铸型开裂，提高了铸件精度。
The use of special technology to control the ceramic thickness of 2 ~ 3mm, the outer sleeve of graphite or metal, which can effectively reduce and limit the decarburization layer, while thin-walled ceramic also greatly reduce the mold off Shrinkage and mold cracking, improve the casting accuracy.
