Die casting has been practiced for about 100years. It is an excellent method for producing complex components in large quantities, with the mass production of automobiles and electrical appliances,especially aluminium dies casting has developed very rapidly.
In pressure die casting molten metal is transferred to the metal die under pressure by the die casting machine.The molten metal is allowed to cool and solidify in the metal mould.Then the die is opened and the component is taken out.In most cases the die cast components are utilised without any further operations.
