Gold Melting Furnace 1kg Automatic Melting Furnace Machine The maximum adjustable temperature of our product is 1150 degrees celsius. Thus, the melting furnace is perfectly designed for the melting of precious metals. The melting point of silver is 962 degrees celsius, gold is 1064 degrees celsius and copper is 1084 degrees celsius. The regulation of the melting temperature is very user-friendly via a highly modern PID module. This module allows the digital adjustment of the setpoint temperature to the degree accurately. The PID module monitors the actual temperature in the melting chamber at 2-second intervals so that it does not overheat or cool down. The temperature is kept constant around the melting point.
