IGBT Gold Induction Melting Furnace is the most advanced melting technology in the Gold, Silver, Platinum, Copper, Steel Melting Industry. This model gold melting furnace is the best choice for lab, jewelry shop, research institute, and mining company comparing with gas melting furnace and resistance melting furnace.

CDOCAST Provided several series of systems & equipment pieces for melting gold, silver, and copper.

1: The Integrated Type Gold Melting Machine is an entry-level system designed for small shop melting. Which capacity varies from 1kg-10kg, And the power supply range from 5kw to 45kW. There are mainly two types of crucibles: graphite or ceramic crucibles using two different load circuits. (Remark: graphite crucible suitable for, Gold, Silver, Copper, ceramic crucible Crucible suitable for metal: Platinum, Palladium, Steel)

2:For larger volume melts, Cooldo  Recommended Our Tilting Gold melting furnacesThese types can be suitable for 10kg-500kg capacity with power supplies from 5kw to 300 kW. The Tilt gold melting furnaces are equipped with either Hand-Wheel, Electro-Mechanical, or hydraulic tilt systems, depending upon the load being melted and customer preference, The tilting Types can be equipped with The Siemens PLC control system, also the temperature controller, Blowing Mouth, Travel Switch… is equipped, Etc to operate the system and monitor the critical operating data.  

CDOCAST gold melting Furnace has the superior quality with the temperature control system as the optional system, and All Our Gold Melting Furnace adopt the inside-built water cooling system which the customers just need to connect the water pipe with flow water that can run the machine normally.

Cooldo Gold Melting Furnace Advantage:

1), Adopt the IGBT Technology which can save 15-30% energy than the KGPS technology with full load.
2), Easy installation and convenient maintenance according with the video or operation manual from CDOCAST.
3), One Square meter or more less space for the furnace occupied.
4), Easy exchange the crucible if you melting different metal.
5), 24 hours continuously working on duty with full load.
6), low pollution, low noise and low power consumption.
7), The metal furnace with full protection switch like over voltage, over-current, over-heating etc for avoid error operation.


Cooldo Gold melting Furnace has a stable Operation with Unbelievable melting speed. Typical melt times for a full load of material are about 15 minutes for the first melt and 10 Minutes for subsequent melts.
