Aluminum Die Castng
(1) malleable cast iron is a certain range of chemical composition of white cast iron by annealing the resulting solid graphite graphite cast iron floc group. It has a very high plasticity, it is “malleable” Aluminium Die Casting name, in fact, is not forged, but it can be a good bend, elongation up to 15% strength is also high.
(2) Pressure casting is liquid or semi-liquid metal, filled with high-speed die casting mold cavity, and rapid solidification under pressure molding, casting and get a special casting method is generally applicable to non-ferrous metals. These two processes die casting from the use of the material, size and shape of the product, process methods, products, applications are different
Die casting technology and production
The book was discussed in detail the basic knowledge and production of the die casting technology. The main contents include casting, die casting machine principle, parameters of die casting process and its determining method, die casting pouring system and die casting die structure design, quality control, production of the die casting Aluminum Die Casting and die casting workshop operation management. Also introduced CAD for die casting die and die casting filling process simulation technology and application etc..
