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, which can not be produced by bending pipes and other processes. In order to produce such products with irregular shapes (hollow or solid inside), a wax mold → sand mold → liquid material filling molding process is adopted.
优点：可以根据不同的蜡模做出款式多变的产品。
Advantages: products with various styles 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。
Disadvantages: the precision of the formed blank is not high, and the surface roughness is large.
