1. Natural and environmentally sound
Zinc is a part of the cycle of nature, and can be reused. Zinc melting point is low compared to most other materials. Thus the energy consumption when die casting zinc is reduced.
2. Great creativity
Die casted zinc meets the demand for creativity in the construction and design process. Several parts can be integrated into one common casted part. Self lubricating characteristics of the zinc alloy is used to avoid the use of lubrication bearings. For the benefit of total costs.
3. Surface finish advantages
A lot of surface coating options are available in order to add more attractive aesthetic and functional characteristics to the zinc parts.
4. Low price
Long lasting durable zinc die casting moulds and fully automated production keeps the costs down.
5. Strong characteristics
Die casted zinc parts have a high mechanical strength, elasticity and impact ductility. Often die casted zinc parts are a better choice than for example parts in aluminium, plastic or milled parts.
6. Reduced weight
Zinc is heavier than aluminium and magnesium, an advantage if you need a heavier component such as a lamp support. On the other hand die casted zinc parts can be optimized, and the weight reduced considerably – without affecting the strength and complexity.
7. Precise and complex
Die casted zinc can have very small wall thickness, and very narrow tolerances make it possible to cast parts ready for installation of bearings. Precise and very small details can be included in the casting – even in complex geometries.
8. Good conductive abilities
Die casted zinc has good electric and heat-conducting characteristics. An advantage if you have a high demand for heat transfer, but have limited space, as example in LED lighting systems.
9. Sound absorbing
Die casted zinc is sound absorbing therefore it is used for mechanics with movable parts, chains or the like. As example in remote window control systems, where noise should be minimized.
10. Protection shield
Die casted zinc has built in EMC protection. The shielding properties are optimal compared to traditional metal sheet solutions.
The North American Die Casting Association says on its website that it considers metal casting to be “America’s most fundamental industry.” It’s not surprising that a metal casting trade association would describe die casting services as fundamentally important, and it’s likely that other trade associations for other sectors of industry would dispute the NADCA’s claim. But there’s no denying that casting is an essential element in our industrial infrastructure.
The NADCA sites some reasons for why it considers its members’ products to be so important to American industry. According to them, 90% of all finished American manufactured products involve metal castings in some way. They say also that die casters make a $7 billion annual contribution to the country’s economy, and that the die casting industry employs 50,000 workers in direct and indirect capacities.
A lot of operations within commercial and industrial sectors rely on access to cast metal products. These operations range from advanced, high-tech operations such as aerospace manufacturing and medical products companies, to low-tech consumer products manufacturers, such as lawn care products manufacturers. You can find metal castings in space ships and in toy models of space ships. They can be found at all levels of industry and commerce in an extensive variety of products and contexts.
Die casting in particular is considered to be a comparatively sustainable metal forming process. According to the NADCA, more than 95% of North American die castings made of aluminum are composed of recycled aluminum. This reduces the need for new aluminum mining, and it also reduces the amount of aluminum that finds its way into waste areas like landfills. This also makes the process more economical. Additionally, scraps produced during the die casting process can often be recovered, melted down and then used in future casting. Considering all of these factors, it’s possible that the NADCA might just be right in its claim about the importance of die casting.
