With a legacy of over 40 years in industrial equipment design and manufacturing, Delmer Group is a trusted global leader in specialized thermal processing solutions. Our annealing tunnel furnaces are the backbone of high-volume jewelry production, engineered to meet the exacting metallurgical standards required for gold, silver, and copper processing.

Our furnaces feature two heating chambers that operate with separate heating zones and temperature settings.

A tubular frame and panels with louvres for air exchange are used to construct furnaces. General maintenance interventions are easier with a tubular system.

Heating muffles are made of resistance and unique, highly thermally efficient refractory insulating panels. Strong temperature changes can be handled by a special heating chamber made of stainless steel.

Due to belt movement, internal sliding blocks prevent chamber wear and tear. Water is used to cool the cooling chamber. The chambers are held together by a flange, and a nozzle on it allows gas to enter. In order to improve de-oxidation, two burners are placed in front of the tunnel's two ends.

Continuous Annealing for Superior Metal Quality

Our furnaces are designed for precision, consistency, and efficiency, making them ideal for a wide range of applications:

• Jewelry Chains – Exceptional temperature uniformity and advanced atmospheric control ensure chains with optimal ductility, flawless crystalline structure, and long-term durability, even in the most intricate designs.
• Coin Blanks – Our annealing process optimizes molecular structure, preventing cracking or warping during minting, and delivering a smooth, high-quality surface finish.
• Rectangular Plates & Wires – By reducing internal stresses, our furnaces allow for complex shaping, bending, and forming without the risk of fracture, ensuring maximum production efficiency.

Our annealing furnaces are constructed of panels with Louvres for air exchange and a tubular frame. General maintenance interventions are easier with a tubular system.

Heating muffles are made of resistance and unique, highly thermally efficient refractory insulating panels. Strong temperature changes can be resisted by special stainless steel heating chambers.

Protection gas enters the chamber through nozzles. The de-oxidation process is improved by a burner placed in front of the chamber to prevent oxygen entry. Inside is a shovel made of stainless steel.

When annealing metal, you simply push the pale to the bottom of the cooling chamber and drop it into the water tub for instant cooling (or leave it lying in the cooling chamber to cool, taking some time). The tub's treated material is removed either manually or (optionally) with a pneumatic piston.

Delmer Electric Gold Melting Furnace is a compact electric resistance furnace designed for controlled melting of gold, silver, brass, aluminium and other non-ferrous metals for jewellery, casting, ingot and small-batch foundry applications.

Available in 1 kg, 2 kg and 3 kg capacities, the furnace operates on 230 V AC single-phase power and uses a Kanthal (FeCrAl) heating element, K-type sensor and LED temperature controller. The maximum furnace temperature is 1200°C. Typical melting time is approximately 15–20 minutes, depending on metal type, charge size and starting conditions.

Quick Specifications

What Can This Electric Melting Furnace Melt?

The Delmer furnace is designed for small-batch melting of gold, silver, brass, aluminium and its alloys, subject to the suitability of the alloy, crucible and operating conditions. It is used for jewellery manufacturing, casting, ingot pouring, prototyping, small foundry work and educational metalworking.

How Does the Delmer Electric Gold Melting Furnace Work?

The furnace uses electrical resistance heating. Current heats the Kanthal (FeCrAl) coil, which transfers heat to the crucible. The metal is therefore heated indirectly, with no direct electrical contact between the heating element and the metal charge. A K-type temperature sensor and LED controller allow the operator to monitor and set furnace temperature.
