Forging parts have higher strength. They are commonly used in parts under hand tension. Automobiles and ships are common. Forging parts have higher toughness and more torque. For example, the steering arm of automobiles. Casting is a kind of metal molding object obtained by various casting methods, that is, the molten metal is poured into the prepared mold by pouring, injection, suction or other casting methods, and then cooled to obtain the object with certain shape, size and performance.
Investment casting, also known as lost wax casting, is commonly used for precision forging parts: select appropriate investment materials (such as paraffin) to make investment mold; repeat the process of dipping refractory coating on the investment mold and spreading refractory sand to harden and dry the mold shell; then melt the internal investment mold to obtain the mold cavity; bake the mold shell to obtain sufficient strength and burn the residual investment mold materials According to the needs of the products, heat treatment, cold processing and surface treatment are carried out. Except for the aviation and weapon departments, investment casting is applied to almost all industrial sectors, especially electronic, petroleum, chemical, energy, transportation, light industry, textile, pharmaceutical, medical equipment, pump and so on Valve and other departments.
