An induction furnace is accurate with repeatable results, safer and cost-effective way to melt precious metal bearing materials. It uses a high-temperature electric current to melt the metal with an added fluxing agent.
Once the metal is molten it is stirred ensuring the alloying conditions are fully mixed into the melt.
Sampling the melt can be done by glass vacuum pin tubes before the pour or by drilling after the bar has been cooled. Material type will determine the sampling method.
JRI has three furnaces on site, the newest and largest is a 75 Kilowatt induction furnace with a 100 lb. capacity. There is also a 20 lb. capacity furnace and a 4 lb. capacity furnace for smaller lots.
