Die casting is a manufacturing process for producing accurately dimensioned, sharply defined, smooth or textured-surface metal parts. It is accomplished by forcing molten metal under high pressure into reusable metal dies. The process is often described as the shortest distance between raw material and finished product. The term "die casting" is also used to describe the finished product.
The term "gravity diecasting" refers to castings made in metal molds under a gravity head. It is known as permanent mold casting in the U.S.A. and Canada. What we call "die casting" here is known as "pressure die casting" in Europe.
Magnesium is the ideal material for applications where weight saving is a priority, having the lowest density of all structural metals. Almost as light in weight as plastic, magnesium has the advantage of greater strength and rigidity along with inherent EMI shielding, durability, heat-dissipation and full recyclability. Magnesium alloy characteristics:
- The lightest of all structural metals
- Excellent stiffness and strength-to-weight ratio
- Outstanding EMI shielding properties
- High conductivity, electrical and thermal
- Withstands high operating temperatures
- Cost-effective against plastics
- High dimensional accuracy and stability
- Exceptional thin wall capability
- Good environmental corrosion resistance
- Good finishing characteristics
- Full recyclability
