The Eco Friendly Face Of Die Casting

Most of the businesses have become environmentally conscious these days and it has urged them to look for sustainable product options and eco-friendly manufacturing processes. The implementation of eco-friendly manufacturing process has helped many businesses to reduce the negative impact on the environment considerably.

Die casting is one of the most popular and highly efficient eco-friendly modern manufacturing methods. However, many businesses fail to take note of the fact that most highest-quality die casting components are recyclable. Die casting process offers reliable results for many industries along with meeting the necessary tenets of the “reduce, reuse, and recycle” approach.


Many types of metal casting methods require a sand mold. Unfortunately, most of the sand molds can be used only once and it should be reserved for all metal casting process. The processes that use a sand mold also waste a great amount of energy.

One the other hand, die casting process doesn’t require a sand mold, instead it uses a permanent die. One of the major advantages of die casting is that the dies can be used almost 100,000 times or more before they are replaced. This makes die casting a much more energy efficient process than many other metal shaping processes.


Let us assume that a die has eventually reached the end of its useful lifespan. In this scenario, professional die casting companies ship the used dies to specialty mills to retool them instead of discarding or recycling them. This process will allow the die to accommodate slightly larger or different products.

Additionally, some die casters prefer to recast the used die through minimal processing. This, in turn, helps them considerably reduce the carbon footprint and keep the use of raw material to a minimum.


Most materials used in die casting process can be easily recycled. Aluminum, which is one of the most common metals used in die casting, is energy efficient, cost effective and easily recyclable. Furthermore, in the recycling process, aluminum die extrusion doesn’t require melting but it does produce high amounts of usable materials even with a very little energy input.

Statistcis shows that more than 50 percent of the new aluminum produced in the country came from recycled aluminum. This is one of the reasons why aluminum has become the favorite casting metal for many die casting companies.
