Benefits of recycled zinc

In today's business landscape, sustainability has moved beyond buzzword status; it is now a fundamental commitment across industries. Zinc, with its remarkable recycling rate ranging from 70% to an impressive 90%, has become a significant contributor to sustainable die casting practices. This translates into the recycling of 70 to 90 tons of zinc for every 100 tons produced, highlighting its pivotal role in promoting a circular economy. Zinc is an excellent metal for recycling because the quality of recycled zinc is the same as that of primary zinc, meaning it can be used to make the same products. This is because zinc is a pure metal and does not degrade when recycled. 

The sustainable cycle of zinc recycling for die casting

The process of transforming zinc from discarded material into a valuable resource for die casting is carefully managed.

It begins with collecting zinc-containing materials such as galvanised steel, zinc alloys and zinc oxide. Once considered waste, these materials now form the foundation of sustainable die casting.

To achieve the purity required for manufacturing, precise pre-treatment removes impurities such as lead, tin and nickel, ensuring that recycled zinc meets the highest standards for producing high-quality metal parts.

Pre-treated materials are transformed in the melting furnace, becoming molten zinc ready for forming metal parts.

With precision, molten zinc is shaped into ingots or moulds that meet specific die casting requirements. This demonstrates zinc's remarkable adaptability in sustainable die casting, including within recycling processes.

Benefits of recycled zinc for manufacturing metal parts

• Quality and performance: Recycled zinc maintains the same high-quality standards as its primary counterpart. It preserves structural integrity, ensuring that metal parts manufactured through die casting deliver exceptional quality and performance.
• Cost efficiency: Die casting with recycled zinc benefits both the environment and your cost base. Reduced water consumption, lower energy costs and efficient zinc transportation all contribute to cost savings in die-cast metal part production.
• Customisability: Recycled zinc is highly versatile, enabling the production of metal parts tailored to your exact die casting specifications. This adaptability provides die casting manufacturers with a wide range of design possibilities.
• Sustainability: Choosing recycled zinc for your die casting process supports sustainability goals. It significantly reduces water use, curtails the need for additional mining and minimises the environmental footprint associated with die-cast metal parts.
