Process Die casting
Used for net-shape forming (dimensional accuracy and surface details) of high-quality parts with complex shapes. Thanks to the high pressures involved, very thin walled parts can be obtained. In Europe the process is also called "pressure die casting".

The process involves the use of a piston which traps a certain volume of molten metal and forces it into the die cavity through a nozzle. The pressure is maintained until the metal has solidified. Very high production rates.

Normally, metals with melting-points lower than steel are used. For low melting-point metals like zinc, tin and lead, hot chamber die casting is used. For other metals, cold chamber die casting is applied.

Price notes C = 2.36* cost of the material + 5.13
Formula suited for rough cost estimates (DKK/part) of pressure die casted components produced in medium to large volumes (>30,000 parts).
The formula includes post-machining and profit.
