[Metal electric melting furnace]: 1500W electric furnace can be heated to 1150℃/2102℉ and melt gold, silver, copper, aluminum and other metals with melting points lower than 1100℃ within 40-55 minutes [High-quality crucible]: Graphite crucible has excellent thermal conductivity, ensuring a smooth and efficient melting process while withstanding high temperatures; the groove design facilitates the pouring and filling of the melt [Safety protection]: The base of the melting furnace is enlarged, the center of gravity is more stable, two carrying handles are added, and a heat insulation net is installed, making it easier to carry and effectively insulated [Temperature control]: The metal melting furnace kit is equipped with an advanced PID module and digital control system, which monitors the actual temperature in the furnace every 2 seconds to prevent overheating or overcooling [Application]: Digital automatic smelting furnace is suitable for processing precious metals such as gold, silver, and copper. It is not only an ideal choice for professional use in industry and workshops, but also a good helper for home smelting
