01 · Tube
Welded sheath tube
Stainless strip is roll-formed, TIG-welded and sized in our own tube mill – AISI 304, 316L and 321.
Production · Kahramankazan, Ankara
From stainless strip to a tested element – under one roof.
A heating element is only as good as the process behind it. Tube welding, wire coiling, MgO filling, rolling, annealing, forming, brazing, assembly and final test all run in our own plant – no outsourced critical step.
Process know-how since 1959, built into traceable lines that change over between product codes for OEM programmes in more than 60 countries.

The process
Eight steps. One accountable plant.
Every step that decides the life of a heating element happens under our own roof, on our own machines, with our own people – so a drawing becomes a repeatable series part.
02 · Coil
Resistance wire coiling
NiCr and FeCrAl wire wound to the calculated pitch – the coil sets power, surface load and cold zones.
03 · Fill
MgO filling
High-purity magnesium oxide is vibrated around the centred coil and the tube ends are closed.
04 · Roll
Rolling
Roll reduction compacts the MgO to its final density – the basis for insulation and heat transfer.
05 · Anneal
Bright annealing
Annealing under protective atmosphere relieves rolling stress and restores ductility for bending.
06 · Form
CNC forming
Programmed bending to the drawing – loops, rings, serpentines and three-dimensional forms.
07 · Assemble
Brazing & assembly
Flanges, brackets, terminals and sensors are brazed, welded and sealed (STF) in fixtures.
08 · Test
100 % final test
Resistance, dielectric strength and insulation resistance on every element – then labelled and packed.
Three production lines
Organised by application – not by machine.
Each line has its own planning, tooling and test set-up, so a high-volume oven programme and a special industrial element never compete for the same capacity.
Line 1
Mass production for air heating and cooking applications
Grill, bake, fan-ring and defrost elements for built-in and freestanding ovens, mini ovens, contact grills and air-heating units – formed on CNC benders in high-volume series.
Line 2
Mass production for water and liquid heating applications
Immersion, flange and screw-plug elements for water heaters, washing machines, boilers and beverage equipment – with Tormec stem thermostats where the appliance needs them.
Line 3
Industrial and special production
Heavy-duty and custom elements for industrial cooking, commercial laundry and other professional equipment – small and medium batches, special sheaths, terminations and flanges.

Built for OEM programmes
Traceable and scalable.
High volume, high mix: our lines are set up to run long series and to change over between product codes without losing repeatability.
- 100 % in-line electrical test before packing, recorded against the batch.
- Batch traceability from every carton back to wire, tube and MgO lots and test records.
- Statistical process control on the parameters that decide life: compaction, resistance, insulation.
- Capacity planned with your forecast, so delivery performance holds through peak seasons.

Send it to the team that will build it. We confirm feasibility, materials and a target price – and propose improvements where they make the element last longer.
