阿里巴巴Investment casting is based on the final product as a copy, the paraffin material is pressed into a precise and clean wax mold, and the wax mold is coated with multiple layers of refractory material. After the slurry is dried and hardened, the wax mold solidified in the mold shell is melted to make it flow out, and the mold shell is roasted to make it strong and dry. Finally, the molten liquid metal is poured into the mold shell.
熔模铸造是以最终产品为摹本，将石蜡类材料压制成精确光洁的蜡模，在蜡模上涂敷多层耐火材料，待浆料干燥硬化后形成型壳，然后将凝固在型壳内的蜡模熔化使之流出，再将型壳焙烧使之坚固、干燥，最后再将熔化的液态金属浇注入型壳中，
After the liquid metal is cooled and solidified in the mold shell, it becomes a precise and smooth casting.
液态金属在型壳中冷却、凝固后即成为精确光洁的铸件。
This casting process can produce precision complex, close to the final shape of the product, can be processed or little processing can be directly used metal parts or exquisite crafts, so it is a near-net shape of metal liquid forming process.
这种铸造工艺可以生产出精密复杂、接近于产品最后形状，可不加工或很少加工就可直接使用的金属零部件或精美工艺品，所以，它是一种近净形的金属液态成形工艺。
China is one of the birthplaces of investment casting technology.
中国是熔模铸造技术的发源地之一。
According to research, lost wax casting has appeared in the Spring and Autumn Period 2500 years ago.
据考证，在距今2500年前的春秋时期就已出现了失蜡铸造。
The Zunhe plate from the tomb of Marquis Yi of Zeng unearthed in Suizhou, Hubei Province in 1978 is a representative work of early lost wax casting.
1978年在湖北随州出土的曾侯乙墓的尊和盘是早期失蜡铸造的代表作。
