Continuous Casting Furnace "Etna cD Series : Revolutionizing Precious Metal Production

If you're in the jewelry, precious metals, or fine engineering sectors, look no further than Delmer Group’s Etna cD Series continuous casting furnace. This series, engineered for quality and efficiency, is setting new standards in metal casting—ideal for gold, silver, and copper production.

What is Continuous Casting?

Continuous casting is an industrial process that enables uninterrupted solidification of molten metal into semi-finished forms like wires, plates, tubes, or profiles. Operating under controlled, closed-loop conditions, this system boosts production efficiency, minimizes waste, and ensures consistent quality—far superior to traditional, batch-style ingot casting.

Why Choose the Etna cD Series?

Delmer’s Etna cD Series stands out among continuous casting machines thanks to :

1. Versatile Capacity Ranges

Offering models from cD 10 (10–14 kg capacity) to cD 50 (up to 140 kg), the Etna series serves both small workshops and high-volume production facilities.

2. Advanced Induction Heating

Each unit features a mid-frequency induction system, proudly designed and engineered by Delmer’s Technical division. This ensures rapid, uniform heating without noise pollution.

3. User-Friendly Interface & Robust Controls

The machine offers a graphical LCD panel and thermal printer for process monitoring and logging. Additionally, the membrane keypad simplifies operation, making it easy for users to manage and record production cycles.

4. Reliable Profile Pulling & Cooling System

Driven by a stepper-motor gear and planetary gears, the pulling system assures precise and adjustable feed. Meanwhile, the fully cooled aluminum profile drive—sealed under a durable cover—ensures consistency and easy maintenance.

5. Gas Protection for Quality & Safety

The Etna units feature inert-gas purging to protect molten metal from oxidation. This results in cleaner, denser end-products, essential for high-quality jewelry and technical applications.

6. Optimized Cooling Socket

With water channels and bronze rings to regulate flow, the cooling socket ensures optimal performance. For fast-cooling needs, optional attachments—like trays, shears, and tilting heads—are available

Applications Across Industries

The Etna cD Series is engineered for versatility in : 

• Jewelry production : casting gold, silver, and other precious metals into wires, tubes, plates, and intricate profiles.
• High-purity requirements : inert-gas protection ensures reduction in oxidation—critical for technical or laboratory uses.
• Mid- to high-volume operations : optional accessories like saws, tilting heads, and rapid cooling trays make it ideal for scaling production.

In short, Etna cD units are ideal wherever clean, uniform metal output, low rejection rates, and operational reliability matter.

Advantages of Continuous Casting Machines

Continuous casting systems like Etna bring key benefits:

✅ Superior Quality : Continuous operation reduces defects and yields metals with dense, uniform structures.

✅ Efficiency & Cost Savings : Minimize material waste compared to batch systems and cut down on labor.

✅ Automation Ready : Equipped with digital control and data logging, easy to integrate into smart manufacturing lines.

✅ Scalability & Speed : Fast turnaround through consistent metal feed and adjustable pulling; additional accessories enhance productivity.

How to Choose Your Model

To select the right unit : 

1. Determine Production Requirements – Estimate daily output in kg.
2. Select Capacity Range – Choose cD 10 to cD 50 based on throughput needs.
3. Consider Automation Tools – Decide if you need tilting heads, tray cooling, or cutting tools.
4. Ensure Infrastructure Readiness – Verify availability of cooling water, inert gas, and power (15–24 kW typical).
