Think Zinc

Zinc die casting

Die casting is the process of engineering metal parts by forcing molten metal under high pressure into reusable molds.  These molds, also referred to as dies, can be designed to produce complex shapes with a very high degree of accuracy.  Zinc is the fourth most common metal used in die casting parts and is behind only iron, aluminum, and copper.  It is one of the easiest alloys to cast because it offers high ductility, high impact strength, and is also easily plated. 

Zinc is an ideal metal for die casting due to its strength and hardiness.  It also has excellent electrical conductivity, high thermal conductivity, low raw material cost, and high dimensional accuracy.  Zinc is also an environmentally responsible choice for die casting because it is fully recyclable.  At the end of their product life, these die castings can be recycled and reused in new products by industries such as steel, rubber, agricultural, and pharmaceutical. 

Zinc die casting is used in tons of familiar objects such as household appliances, hand tools, telecommunication devices, computers, and several types of automotive vehicles.  Zinc die casting uses hot chamber machines because of its low melting point and the fact that it does not erode metal pots, cylinders, and plungers.

There are several metals that can be used in the die casting process.  Zinc is a top choice because of the many benefits it offers for creating metal parts.
