Heat treatment can help change the quality of metal casting. It changes the physical and mechanical properties of the castings with the use of a
Rockwell and Brinell hardness are two of the most common tests used to measure the hardness of iron castings The hardness test is done to determine if the hardness and tensile strength still need to be improved with a machining process, especially in producing rough metal castings. The tests are as important as heat treatment and other manufacturing processes.
One of the key elements of a successful casting industry is pattern-making. The final output of the metal casting will look like the sand casting patterns. It is also used to create mold. The pattern material is typically made from wood, metal, plastic, or wax, and they are usually coated with a release agent to ensure that the sand does not stick to the pattern surface.
