The "Volcano" series is the range of continuous casting furnaces with reduced crucible capacity. It is essential to divide the Volcano 3000-5000 models and Volcano 7/12 models, because the first is provided "bench", also matching hooves or feet while the second is provided with a floor structure that allows the use of a roll holder to create profiles on a larger scale. The user interface consists of a keyboard with numeric display Access to the machine body is secured by a tubular frame and movable panel for easy maintenance. The drive system for profile is made aluminium and its completely cooled and driven by a stepper motor coupled to a planetary gear, it should be integrated with the casting chamber. All this system is closed by a cover easy to remove: the access to equipment melting (ceramic jacket, chain bushings, thermocouples) is very fast minimizing time for replacement. The cooling glass, in harmony with the equipment has been refined so that it can offer the best possible performance. The heart of the machine consists of a middle frequency system completely designed and built by the Technical Delmer Department.
The OPDEL® Vulcano cD Series is a high-performance continuous casting furnace designed for precision casting of gold, silver, copper alloys, and other non-ferrous metals. It delivers consistent casting quality with controlled heating for jewellery manufacturing and industrial metal processing.
The Vulcano cD Series is suitable for casting 18kt and 24kt gold, 925 silver, copper alloys, and other non-ferrous metals that require accurate temperature control and continuous casting.
The series includes four models:
- cD 3
- cD 5
- cD 7
- cD 12
The cD 3 and cD 5 are compact bench models, while the cD 7 and cD 12 are floor-standing machines designed for higher production capacities.
The Vulcano cD Series operates up to 1250°C as standard, with selected models offering an optional maximum temperature of 1400°C for advanced casting applications.
Depending on the model, the furnaces can cast from 3.6 kg of 18kt gold up to 12.7 kg of 24kt gold, and up to 6.9 kg of 925 silver.
The Vulcano cD Series is designed to produce a variety of continuous cast profiles, including wire, flat bars (plates), and tubes, with profile sizes varying by model.
Key features include:
- Continuous casting technology
- Operating temperatures up to 1400°C
- User-friendly control panel
- Integrated cooling system
- Gas protection system
- Durable industrial construction
- Optional tool cabinets and water cooling tanks
The cD 3 and cD 5 are compact bench-mounted furnaces suitable for smaller production batches. The cD 7 and cD 12 are floor-standing models that provide larger crucible capacities, higher power ratings, and increased production output.
The Vulcano Series is widely used by:
- Jewellery manufacturers
- Precious metal refiners
- Metal casting workshops
- Foundries
- Industrial metal processing facilities
- Continuous profile production plants
Continuous casting is a manufacturing process where molten metal flows continuously into a water-cooled mould, producing uniform wire, bars, tubes, and other profiles with consistent dimensions and reduced material waste.
Optional equipment includes:
- Enhanced gas protection
- Water cooling tanks
- Tool cabinets
- High-temperature operation up to 1400°C (selected models)
The OPDEL® Vulcano cD Series combines precision temperature control, reliable continuous casting technology, multiple production capacities, durable construction, and efficient cooling systems to deliver consistent, high-quality casting performance for professional precious metal manufacturing.
