Product Details

Product Overview

The 100kg Automatic Medium Frequency Induction Melting Furnace is specially engineered for melting and continuous casting of gold, silver, and other precious metals.
It combines advanced medium-frequency electromagnetic induction technology with automatic feeding and casting systems, allowing consistent ingot production and precise control over the metal temperature and composition.

Key Features

  • Automatic feeding and continuous casting system for small-scale precious metal production
  • Medium frequency induction heating ensures fast and uniform melting
  • Precise temperature control suitable for gold, silver, platinum, and other alloys
  • Compact 100kg capacity ideal for jewelry workshops and small foundries
  • Stainless steel furnace crucible for durability and corrosion resistance
  • Real-time monitoring of furnace temperature, power, and casting parameters
  • Energy-efficient design with stable power output

Applications

  • Gold and silver melting
  • Continuous ingot casting for jewelry manufacturing
  • Small-scale precious metal foundries
  • Alloy and refining production

Melting Process

  1. Material preparation: Sort and clean gold or precious metal scraps, remove impurities.
  2. Charging: Add materials gradually into the crucible to avoid overfilling.
  3. Melting: Heat metals using medium frequency induction, monitor temperature precisely according to melting point.
  4. Alloying (optional): Add alloying elements and stir to ensure uniform composition.
  5. Continuous casting: Pour molten metal into molds automatically via the casting system.
  6. Furnace cleaning: Prepare furnace for the next batch.
