什么是不锈钢的精密铸造
What is Precision Casting of Stainless Steel
在生产不锈钢产品时，有些产品的形状怪异，无法用弯管等工艺进行生产时，为生产这类不规则形状（内部为空心或实心）的产品，采用的一种利用蜡模→做砂模→液态材料填充成型的工艺。
In the production of stainless steel products, some products have strange shapes and can not be produced by elbow technology. In order to produce products with irregular shapes (hollow or solid inside), a process of filling and moulding with wax mould, sand mould and liquid material is adopted.
优点：可以根据不同的蜡模做出款式多变的产品。
Advantages: Variable products can be made according to different wax patterns.
缺点：成型坯料精度不高，表面粗糙度较大。
Disadvantage: The precision of forming blank is not high and the surface roughness is large.
