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.
