Aluminum die casting

1. Aluminum die casting Die casting is a process that produces metal parts by forcing molten metal into reusable steel molds under high pressure. These molds also known as dies are specially designed to produce different shaper of varying complexity with a high level of accuracy and repeatability. Die casting metal helps to produce sharply defined shapes with textured or smooth surfaces. This unique process is widely used in the metalworking industry to manufacture mass produced commercial, consumer, and industrial products. You can manufacture parts ranging from toys to automobile parts to faucets. Die Casting Process In the die casting process, the molten metal is injected under high pressure into the die or the steel mold. Die casting machines are rated in terms of tonnage which is the amount of pressure that can be exerted on the material. The machines typically range from 40 tons to 4000 tons. Advantages of Die-casting  Die-casting is an economical and efficient process that provides a wide range of shapes.  Die-casting is a fast process.  The parts produced are dimensionally uniform. Pressure die casting(Aluminum alloy) In the pressure die casting process the metal is forced into a high grade steel tool at high speed and pressure. The casting temperature is roughly 700°C when casting aluminum and 650°C when casting magnesium. The use of vacuum casting technique is a must in order to achieve superior quality for extremely light and thin walled components.

The need for machining is very low due to the close casting tolerances. Heat treatment of pressure die casting is not possible but due to the high rate of solidification the mechanical properties are good. The tooling costs are considerably higher than for gravity die casting. Important applications are found in the components for mobile telephone base stations and certain mobile telephone applications. The more important reasons for using light metal casting are low weight, mechanical strength, stiffness and electrical properties. Other applications are e.g. components for the power transmission line in the vehicle industry and electronics industry.
