Continuous Casting Machine for Gold, Silver & Copper Alloys | DELMER Italy
The DELMER® Continuous Casting System is engineered for the efficient and uninterrupted production of high-quality rods, strips, billets and custom profiles from precious and non-ferrous metals.
Designed for goldsmiths, jewellery manufacturers, precious metal refiners, copper alloy producers and industrial foundries, the system combines advanced thermal control, robust mechanical engineering and intelligent process management to deliver consistent metallurgical quality with minimal material losses.
Continuous casting technology offers significantly higher productivity, improved metal yield, lower energy consumption and superior surface finish compared to conventional ingot casting methods.
The cD series "ETNA"line includes a variety of continuous casting furnaces with crucible capacities ranging from 10 to 140 kg. A graphical interface and display assist the user in his task. A tubular frame and movable panel secure access to the machine body for simple maintenance. The profile drive system is made of aluminum, is fully cooled, and is powered by a stepper motor coupled to a planetary gear; it should be integrated with the casting chamber.
All of this system is closed by an easily removable cover: entry to melting equipment (Ceramic jacket, chain bushings, thermocouples) is very quick, minimizing replacement time. The cooling socket has been enhanced in accordance with the equipment so that The cooling socket has been refined in tandem with the equipment to provide the best potential performance.
The machine's heart is a mid-frequency system designed and constructed entirely by the Technical Opdel. These furnaces are frequently used for special profiles requiring a large quantity of metal to be melted. It can use accessories such as shears or saws to trim profiles and trays to cool them. In some cases, an additional tilting head can directly fill the empty crucible with liquid metal to minimize production slowdown.

Our annealing furnaces are constructed of panels with Louvres for air exchange and a tubular frame. General maintenance interventions are easier with a tubular system.
Heating muffles are made of resistance and unique, highly thermally efficient refractory insulating panels. Strong temperature changes can be resisted by special stainless steel heating chambers.
Protection gas enters the chamber through nozzles. The de-oxidation process is improved by a burner placed in front of the chamber to prevent oxygen entry. Inside is a shovel made of stainless steel.
When annealing metal, you simply push the pale to the bottom of the cooling chamber and drop it into the water tub for instant cooling (or leave it lying in the cooling chamber to cool, taking some time). The tub's treated material is removed either manually or (optionally) with a pneumatic piston.

Applications
Suitable for gold, silver, copper, brass and other suitable non-ferrous metal melting where controlled pouring is required. Typical applications include jewellery manufacturing, bullion production, precious-metal processing, recycling and casting operations.
New Digital Induction Technology
The furnace is powered by the new digital STROMBOLI Series induction technology, the upgraded induction-melting architecture used across Delmer static and tilting configurations. Final system configuration should be selected according to material, charge weight, target temperature, melting cycle, production rate and electrical infrastructure.

Model data requires confirmation
The existing specification table lists vD 1 and vD 2, but its power and crucible-capacity figures appear inconsistent with the model columns. Ask Delmer to confirm model-specific power, gold-karat capacity, silver capacity, flask limits and electrical requirements before purchase. No unverified capacity guarantee is implied here.
Request a configuration review
When enquiring, specify the metal/alloy, typical batch weight, target output, flask dimensions, site electrical supply and whether optional granulation is required.
