Gold Cupellation Furnace / Gold Testing Furnace

Additional Details

Cupellation is a refining process in metallurgy, where noble metals, like gold and silver, are separated from base metals like lead, copper, zinc, arsenicetc treated using high temperature and controlled operations. These are made of silicon carbide heating element & innovative thermal insulating lining is used which helps to reduce energy consumption as well as skin temperature of the furnace and helps operator to feel comfortable. These high-quality furnace melt/test Gold up to 20 kgs capacity.

Special Features of Gold testing Furnace are

• All types of furnaces for precious metal industry
• High density insulation technique used for reducing energy consumption as well as skin temperature.
• Cupellation furnaces & furnaces for the lost wax processes
• More than 100 furnaces operational in the melting & testing of gold & silver
• Innovatively designed for easy maintenance where the heating element can be changed by any laymen
