【HIGH-EFFICIENCY OPERATION】: This 1500W electric furnace can reach a maximum temperature of 1150℃/2102℉, melting metals with melting points below 1100℃, such as gold, pure silver, pure copper, and aluminum, within 40-55 minutes. Suitable for professional environments such as industrial settings and workshops. 【HIGH-PURITY GRAPHITE CRUCIBLE】: The crucible is made of pure graphite, ensuring high-temperature resistance. The crucible is rotary-formed to maintain ore stability, with a smooth, corrosion-resistant inner wall. The grooved design facilitates pouring and filling of the melt. 【PRECISE CONTROL】: The furnace kit is equipped with an advanced intelligent digital display for real-time temperature monitoring, providing a precise and convenient metal smelting experience. The actual furnace temperature is monitored every 2 seconds to prevent overheating or undercooling. 【NEW UPGRADED DESIGN】: The widened base of the furnace improves stability, and the addition of two handles and a heat insulation mesh enhances comfort, prevents contact with the furnace wall at high temperatures during heating, and provides effective insulation. 【VERSATILE APPLICATIONS】: This compact 1kg/2kg/3kg digital automatic melting furnace is ideal for professional applications. Made with high-quality materials, it meets the needs of industrial and workshop settings and is suitable for processing precious metals such as gold, silver, and copper.
