Zinc A Greener Option

More Eco-Friendly

Zinc is 100% recyclable. All byproducts of the casting process can be re-melted and cast again, unlike its plastic counterparts. We can even recycle painted and plated parts and recapture the zinc for reuse, making zinc a greener alternative. Check out our Environmental Impact Policy for more on Deco’s commitment to sustainability.

Less Fuel Cost, Smaller Carbon Footprint

Zinc melts at around 800 degrees Fahrenheit. However, aluminum requires 1200 degrees Fahrenheit. Aluminum casting requires extra heat, which requires more fuel in the production process. Therefore, zinc has a smaller carbon footprint than aluminum, making it a greener option.

Producing a Better Part

Thinner Walls, Stronger Parts

Zinc alloys are stronger per weight than other materials. This means zinc castings may be produced with thin walls and less material and still be designed to optimize strength in ways other materials cannot. Aluminum’s cost per pound may appear less, but aluminum castings require more material and cost for the same strength.

Tighter Tolerances, Less Machining

Zinc alloys allow us to produce parts with tighter tolerances than aluminum or plastic. Zinc’s precision is better than other materials, which allows us to design features that do not require more expensive machining that other materials require.

Fewer Failures

Zinc alloys have high fluidity when the alloy is molten. This produces a resilient casting with greater impact resistance and rigidity than its plastic and aluminum counterparts.

Better Adhesion

The surface of a zinc casting allows for great adhesion of many finishes to its surface, from powder coatings to plated finishes.

More Versatility

The variety of zinc alloys allow us to maximize strength, rigidity, or fluidity in our castings.
All in all, these characteristics allow us to make a better part with zinc than we could with other materials.

Production Benefits

Longer Tool Life

A typical zinc mold can last 10 times as long as an aluminum mold. The die-casting process for zinc is much less corrosive to the mold than aluminum. If the tool cost is a large percentage of the production costs, using zinc instead of aluminum can provide significant savings.

Faster Production

The hot-chamber process has a much higher cycle-rate, allowing us to produce more parts in the same amount of time. The time savings transfers into cost savings for our customers. While aluminum is typically ladled into the mold, we are able to inject zinc into our molds.
