Trucks used precision steel casting

Trucks used precision steel casting manufacturing process: Make the fusible material into fusible models, then these models are coated with several layers of special refractory coatings to form a monolithic shell after drying and hardening. They are then melted from the shell by steam or hot water. The model is removed, and then the shell is placed in a sand box, and the dry sand is covered around the mold. Then, the mold is placed in a roaster and subjected to high-temperature roasting. After the mold or shell is fired, the molten metal is poured into the mold to get the casting. With the workers machining and inspection, the truck used steel casting are of high quality and good accuracy.
