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.
Zinc's high strength and hardness means that it is the ideal alternative to machined, pressed, stamped and fabricated items. Complex net-shaped zinc housings with precise thin walls give excellent electrical performance and shielding properties to electronic connectors as well as shields, chassis and frames for handheld telecommunications and computing. Small, intricate components are used in many applications, including mobile phone antennae, portable computers, disk drives, precision interlocking gears, heat sinks, shutter mechanisms in cameras and many other consumer electrical and electronics applications. Zinc Alloy Characteristics:
- High strength and hardness
- Excellent electrical conductivity
- High thermal conductivity
- Lowest cost raw material
- High dimensional accuracy and stability
- Excellent thin wall capability
- Ability to cold form, which eases joining
- High quality finishing characteristics
- Outstanding corrosion resistance
- Full recyclability
