薄壁陶瓷型精铸汽车万向节热锻模

Precision Cast of Hot-forging Die for Automobile Universal Joint with Thin-wall Ceramic Mold

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。

A new process is described which uses iron or graphite jacker to limit the thickness of Ceramic mold within 2~3mm. This process can effectively reduse decarburization,decrease slurry shrinkage and mold crack,resulting in increase of cast die precision.
