Die Casting

Choosing the Proper Alloy

Each of the metal alloys available for die casting offer particular advantages for the completed part.

Zinc Die Casting - The easiest alloy to cast, it offers high ductility, high impact strength and is easily plated. Zinc is economical for small parts, has a low melting point and promotes long die life.

Aluminum Die Casting - This alloy is lightweight, while possessing high dimensional stability for complex shapes and thin walls. Aluminum has good corrosion resistance and mechanical properties, high thermal and electrical conductivity, as well as strength at high temperatures.

Magnesium - The easiest alloy to machine, magnesium has an excellent strength-to-weight ratio and is the lightest alloy commonly die cast.

Copper - This alloy possesses high hardness, high corrosion resistance and the highest mechanical properties of alloys cast. It offers excellent wear resistance and dimensional stability, with strength approaching that of steel parts.

Lead and Tin - These alloys offer high density and are capable of producing parts with extremely close dimensions. They are also used for special forms of corrosion resistance.

Advantages of Die Casting

Without question, Zinc die casting or Aluminum die casting is the top-of-the-line method for manufacturing parts. The process can produce parts with perfect finish and astonishing detail, since pressurizing the liquid metal during die casting enables it to form exactly to the mold. Despite these visible advantages, many people can be reluctant to invest in die casting their manufactured parts, fearing the cost associated with top quality processes.

The first thing to note is that Aluminum die casting or Zinc die casting parts have much higher tolerances for heat and pressure than parts made by other methods. Since the metal is forced into the mold, Zinc, or Aluminum die cast parts are slightly denser--and thus more durable--than other cast parts. A savvy businessperson will recognize that this means the parts last longer, leading to a longer life on your product--thus, lower costs of maintenance and replacement, as well as a reputation for quality for your product.

Die casting is an efficient, economical process offering a broader range of shapes and components than any other manufacturing technique. Parts have long service life and may be designed to complement the visual appeal of the surrounding part. Designers can gain a number of advantages and benefits by specifying die cast parts.

High-speed production - Die casting provides complex shapes within closer tolerances than many other mass production processes. Little or no machining is required and thousands of identical castings can be produced before additional tooling is required.

Dimensional accuracy and stability - Die casting produces parts that are durable and dimensionally stable, while maintaining close tolerances. They are also heat resistant.

Strength and weight - Die cast parts are stronger than plastic injection moldings having the same dimensions. Thin wall castings are stronger and lighter than those possible with other casting methods. Plus, because die castings do not consist of separate parts welded or fastened together, the strength is that of the alloy rather than the joining process.

Multiple finishing techniques - Die cast parts can be produced with smooth or textured surfaces, and they are easily plated or finished with a minimum of surface preparation.

Simplified Assembly - Die castings provide integral fastening elements, such as bosses and studs. Holes can be cored and made to tap drill sizes, or external threads can be cast.
