Juyi Eco-Friendly Wax Burnout Furnace with Secondary Combustion
(Environmental Protection Design for Jewelry Lost Wax Casting)

Product Introduction
The Juyi Eco-Friendly Wax Burnout Furnace with Secondary Combustion is a specialized piece of equipment designed for the lost wax casting process in the jewelry industry, widely used for manufacturing bracelets, pendants, earrings, rings, and other fine jewelry.
In the lost wax casting process, wax patterns are used to create molds for metal casting. This furnace melts and burns out the wax models from investment molds, preparing them for the pouring of molten metal.
What sets the Juyi Eco-Friendly wax burnout furnace apart is its secondary combustion system, which re-collects wax fumes and incompletely burnt residues during the dewaxing process, then burns them again to achieve full combustion. This reduces odor, lowers environmental pollution, and creates a cleaner working environment.

Working Principle
1. Heating Stage – The wax burnout furnace uses electric heating elements to raise the temperature to the required dewaxing level. Wax melts at around 60–77°C (140–170°F), but the burnout process operates at much higher temperatures to fully remove the wax.
2. Primary Combustion – Initial heating melts and vaporizes the wax inside the investment mold.
3. Secondary Combustion – Any unburned wax fumes are captured and sent to a secondary combustion chamber, where they are completely burned, reducing smoke and odor.
4. Mold Preparation – The mold is left free of wax residue and is ready for the molten metal pouring stage.

Advantages of Secondary Combustion
• Environmental Protection – Significantly reduces harmful wax fumes and smell.
• Improved Workplace Safety – Cleaner air for operators, complying with stricter environmental requirements.
• Higher Casting Quality – Prevents wax residue contamination, ensuring precise mold cavities.

Features
1. Special Secondary Combustion Design – Fully burns unburned wax vapors, minimizing odor and emissions.
2. Fully Automatic Temperature Control – With over-temperature and break-even protection to prevent overheating and fire hazards.
3. Intermittent Power Outage Function – Controls heating speed, ensures proper gypsum mold sintering, and increases casting yield.
4. Optimized Heating Element Layout – Uniform furnace temperature and excellent air convection for efficient moisture removal from wet molds.
5. Safety Door Switch – Automatically shuts off power when the furnace door is opened.
6. High-Temperature Resistant, Lightweight Materials – Energy-saving, efficient, and durable.
7. Easy Maintenance – Heating wire replacement without dismantling the furnace body or refractory plate.

Applications & Industry Use
• Jewelry Manufacturing – Lost wax casting for gold, silver, platinum, and other precious metals.
• Metal Arts & Crafts – Small-scale artistic casting workshops.
• Research & Education – Teaching and prototyping in casting techniques.
