There are several types of casting used in manufacturing processes.

• Sand casting: uses sand as the mold material

• Investment casting: uses a wax pattern that is coated with a ceramic material

• Die casting: uses a metal mold to produce complex shapes with high accuracy

• Centrifugal casting: molten metal is poured into a rotating mold

• Continuous casting: used for producing long, continuous metal shapes

• Shell molding: uses a resin-coated sand mold

• Lost foam casting: uses a foam pattern th...read more

Heat treatment is a process used to alter the physical and mechanical properties of materials through heating and cooling.

• Heat treatment involves heating a material to a specific temperature and holding it at that temperature for a certain period of time.

• The purpose of heat treatment is to change the material's microstructure, which in turn affects its properties such as hardness, strength, and ductility.

• Common heat treatment processes include annealing, tempering, quenching,...read more
