Design is the first step of realization of a componenet which will be aluminized. Cognizing the demands from the component is the key point of the creating the best design of the die system. Acccording to the demands from the product ideas created for the part which will be find body in the final product. According to the to the part requirements as, mechanical requirements, tightness requirements produciton quantity, mainteince, after cast surface treatment ,after cast machining on the part, are considered to develop more efficient die system.
