ETNA Series, VULCANO Series & STROMBOLI Series

Inspired by the Power of Fire. Engineered to Measure Value.

WE MEASURE VALUE SINCE 1987

Continuous casting is one of the most important technologies in modern precious metal manufacturing. From jewelry production and refinery operations to bullion manufacturing and industrial metal processing, manufacturers rely on continuous casting to transform molten metal into high-quality semi-finished products with exceptional consistency and efficiency.

Inspired by some of Italy's most renowned volcanic landscapes—Etna, Vulcano and Stromboli—Delmer's continuous casting platform reflects the controlled transformation of molten metal into valuable products through precision engineering, temperature control and metallurgical expertise.

Just as nature transforms molten material into structures that endure for generations, Delmer continuous casting systems are designed to convert precious metals into high-quality rods, strips and profiles that become the foundation of world-class jewelry, bullion and industrial products.

Italian Engineering Heritage

For decades, continuous casting technology developed within Italy's precious metal manufacturing industry has supported jewelry manufacturers, refineries and bullion producers around the world. Delmer continues this tradition by combining practical manufacturing experience, modern induction technology and proven continuous casting principles inspired by the engineering heritage of OPDEL and the Italian precious metal industry.

Why Continuous Casting?

Continuous casting has become the preferred manufacturing method for producing high-quality precious metal feedstock.

Compared with traditional ingot casting methods, continuous casting provides:

Improved Precious Metal Recovery

Reduced handling and controlled solidification help minimize gold and silver losses during production.

Superior Metallurgical Quality

Controlled cooling improves grain structure and downstream processing performance.

Higher Productivity

Continuous production increases throughput while reducing manufacturing bottlenecks.

Better Surface Quality

More consistent casting conditions produce smoother products requiring less downstream preparation.

Reduced Manufacturing Costs

Improved yield, lower labor requirements and greater efficiency contribute to enhanced profitability.

Frequently Asked Questions

Why are the Delmer series inspired by volcanoes?

The ETNA, VULCANO and STROMBOLI Series draw inspiration from the transformation and controlled management of molten material. Continuous casting similarly relies on precise control of temperature, flow and solidification to transform molten metal into valuable products.

What is continuous casting?

Continuous casting is a process that converts molten metal into rods, strips, profiles and other semi-finished products through controlled solidification and continuous withdrawal.

Which metals can be processed?

Gold, silver, platinum, palladium, copper, brass and many specialty alloys can be processed using Delmer continuous casting systems.

What products and batch size can be manufactured?

Manufacturers commonly produce rods, strips, plates, wire feedstock, chain feedstock, bullion feedstock and other semi-finished materials.

Small Production

3–12 kg systems

Medium Production

10–50 kg systems
