In mold making, we usually hear casting and forging. What is the difference between the two manufacturing processes? One casting Casting is a process in which a metal is smelted into a liquid that meets certain requirements, poured into a mold, and cooled, solidified, and cleaned to obtain a casting (part or blank) having a […]
Casting mold means that in order to obtain the structural shape of the part, the structural shape of the part is made in advance with other easily formed materials, and then the mold is placed in the sand type, so that a cavity having the same structural size as the part is formed in the […]
Lost foam casting has many kinds of processing methods in China. Different lost foam casting methods have different requirements on coating properties. The casting system and casting body have different requirements on the properties of the material. The gas permeability of the lost foam coating is accurate. It should be permeability, and the permeability of […]
