Melting is a mixture of science, technology, art and industry. Although casting industry has progressed scientifically, in practice it is still the role of experience, tastes and art of molding, which ensures the preparation of a perfect product. This fact is one of the most basic methods of production, since about 50% of the weight of all machine parts is made in this way. Ghaem Co. is using alloys with special aluminum compounds for casting, which has doubled the quality of its products.
