铸造法兰的制作工艺比较简单，流程就是将烧好的材质液体倒入特的磨具里面，经过加工成型之后就形成了铸造法兰，由于铸造的法兰有些许的沙眼，所以一般都是将其表面进行喷塑处理，后完整的铸造法兰就成型了，这种法兰的制作工艺比较简单，造价比较低，所以在价格方面也是比较实惠的。在使用方面也可以广泛的用于各个地区而不受损。
The manufacturing process of casting flange is relatively simple. The process is to pour the burned material liquid into the special abrasive tool. After processing and forming, the casting flange is formed. Because the casting flange has some trachoma, the surface of the casting flange is usually sprayed, and then the complete casting flange is formed. The manufacturing process of this kind of flange is relatively simple and the cost is relatively low. So the price is more affordable. It can also be widely used in various areas without damage.
