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.

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.
Why Choose the Delmer Electric Furnace?
- Designed for small-batch melting of gold, silver, brass and aluminium
- 1 kg, 2 kg and 3 kg capacity options
- Maximum furnace temperature of 1200°C
- Kanthal (FeCrAl) heating element
- K-type sensor with LED temperature display
- 230 V AC single-phase electrical supply
- Compact 8 kg design
- Glass-wool insulation and insulated lid for heat retention
- Typical melting time of approximately 15–20 minutes, depending on conditions
Which Capacity Should You Choose?
1 kg: Suitable for jewellery workshops and smaller batches where compact size and lower power are priorities.
2 kg: Suitable for workshops requiring a larger melt batch while retaining a compact furnace format.
3 kg: Suitable for larger small-batch production, casting and foundry applications.
Electric Furnace vs Induction Furnace
An electric resistance furnace heats the crucible through a Kanthal heating element and is a practical choice for compact, low-volume melting. An induction furnace uses electromagnetic induction and is generally preferred where faster melting, higher throughput or different process requirements justify a more advanced system. Choose the furnace technology according to batch size, production rate, metal, process and available electrical infrastructure.

Frequently Asked Questions
Can this furnace melt gold?
Yes. The Delmer electric melting furnace is designed for gold melting as well as silver, brass, aluminium and other suitable non-ferrous metals.
What is the maximum temperature?
The maximum furnace temperature is 1200°C.
What capacities are available?
The furnace is available in 1 kg, 2 kg and 3 kg capacity variants.
What power supply does it need?
It uses 230 V AC single-phase power. The rated power is 850 W, 1300 W or 1700 W depending on the selected capacity.
How long does it take to melt metal?
Typical melting time is approximately 15–20 minutes, but actual time varies with metal, alloy, charge size and starting temperature.
Is it suitable for jewellery manufacturing?
Yes. Its compact design, programmable temperature control and 1–3 kg capacities make it suitable for jewellery workshops and small casting operations.
How does an electric melting furnace differ from an induction furnace?
An electric furnace uses resistance heating through a heating element, while an induction furnace heats the metal through electromagnetic induction. The best choice depends on batch size, speed, process and production requirements.
Can it be used for aluminium and brass?
Yes, the product is specified for aluminium, its alloys and brass, subject to suitable crucible selection and operating conditions.
