Used crucible furnaces
A crucible furnace is a melting or holding furnace in which the metal to be kept warm or melted is located in a crucible. A distinction is made here between tilting and ladle furnaces.

Furnaces
Used furnaces are a central part of modern foundries, die casting plants and aluminium recycling facilities. They are used for melting, holding, dosing, remelting and heat treatment of aluminium, magnesium, brass, zinc, tin and lead alloys.
FISS Machines offers used melting furnaces, holding furnaces, dosing furnaces, crucible furnaces, induction furnaces and aluminium recycling furnaces. Depending on the system, charging equipment, molten metal transport, ingot loading, ingot casting belts, furnace controls and additional peripheral equipment may already be part of the solution.
Which used furnaces does FISS Machines offer?
The right furnace depends on whether metal needs to be melted, held, dosed, recycled or heat-treated. Die casting, gravity die casting, low pressure casting and recycling each require different furnace concepts.
Dosing furnaces
Dosing furnaces are mainly used in aluminium and magnesium die casting when molten metal must be held at temperature and dosed reproducibly.
View dosing furnacesCrucible furnaces
Crucible furnaces are melting or holding furnaces in which the metal is contained in a crucible. Depending on the design, tilting or bale-out furnaces may be used.
View crucible furnacesAluminium recycling furnaces
Recycling furnaces are used for remelting aluminium scrap, chips, return material, ingots and other input materials.
View recycling furnacesInduction furnaces
Induction furnaces provide electrical heating through electromagnetic induction and are used for melting or holding depending on the application.
View induction furnacesOther industrial furnaces
This includes special furnaces, heat treatment furnaces, annealing furnaces and other furnace systems for specific foundry and industrial requirements.
View other furnacesThe furnace determines the metal flow in the foundry
In a foundry, the furnace is not just a heat source. It influences melt quality, temperature stability, energy use, cycle timing, dosing accuracy and the availability of the entire casting cell.
Input material
Charge
Ingots, scrap, chips or return material are fed into the furnace.
Melting phase
Melt
The metal is brought to the required processing temperature.
Process window
Hold temperature
The molten metal remains stable, available and ready for further processing.
Casting process
Provide melt
The melt is dosed, transported or directly integrated into the casting cell.
Gas-heated, electrically heated or induction?
With used furnaces, the heating method is an important factor. Gas-heated furnaces can provide high melting rates and are often used for larger systems. Electrically heated furnaces are often interesting when holding, dosing or specific process control is the main requirement.
Induction furnaces provide fast electrical heating through electromagnetic induction. Energy availability at the site, metal type, capacity, melting performance, temperature control, maintenance effort and integration into existing production systems are decisive.
What to check when buying a used furnace
When buying a used foundry furnace, the manufacturer or year of manufacture should not be the only criteria. The decisive question is whether furnace type, metal type, capacity, melting rate, heating method, refractory lining, control system and peripheral equipment match the planned process.
Furnace type: melting furnace, holding furnace, dosing furnace, crucible furnace or recycling furnace
Capacity, melting rate, holding performance and temperature range
Heating method: gas, electric or induction
Condition of refractory lining, crucible, burners, heating elements and insulation
Control system, sensors, temperature regulation and safety technology
Charging systems, ingot loading and molten metal transport
Energy connection, exhaust gas routing, space requirements and foundation
Dismantling, transport, reassembly and possible furnace refurbishment
Used furnaces from established manufacturers
FISS Machines trades used furnaces and furnace systems from established manufacturers. Depending on availability, systems from StrikoWestofen, ZPF Therm, Hindenlang, Rauch, Meltec, Stotek, Nabertherm, Altek, Otto Junker and other manufacturers may be considered.
Furnace refurbishment, refractory lining and project handling
With used furnaces, technical inspection or refurbishment may be useful. Depending on condition and budget, options include new refractory lining, checking the heating system, control system adjustments, safety inspection or refurbishment in the workshop or on site.
FISS Machines supports the selection, evaluation, dismantling, logistics, refurbishment and recommissioning of used furnace systems. If no suitable furnace is currently listed online, FISS can search its international network and check suitable solutions.
Buy or sell used furnaces
FISS Machines supports industrial companies worldwide in buying and selling used foundry furnaces, die casting furnaces and recycling furnaces. In addition to brokerage and international marketing, direct purchase by FISS may also be an option depending on the project.
