At Elekheat, every heating element is produced under standardized industrial processes, precision equipment, and full-cycle quality inspection — ensuring stable performance, repeatability, and long service life.
“We do not assemble heaters — we manufacture them from raw material to finished product.”
Core Production Equipment
Manufacturing precision determines heater reliability. We use dedicated equipment rather than manual fabrication.
Density & Electrical Stability
Ensuring uniform insulation and high density for longer service life.
- Automatic MgO Filling Machine: Ensures uniform insulation packing to prevent short circuits and moisture absorption.
- High-Speed Swaging Machine: Compacts the tube to high density, directly improving thermal transfer and lifespan.
- CNC Coil Winding Machine: Guarantees resistance accuracy for stable wattage output.
- Annealing Furnace (1050°C): Removes stress to prevent cracking during heating cycles.
Mechanical & Structural Precision
Precision forming and welding for industrial safety.
- CNC Bending Machine: Precise 3D forming ensures dimensional consistency for easy installation.
- TIG Welding Station: Creates leak-proof joints essential for fluid heating safety.
- Flange Welding Platform: Ensures high pressure resistance for industrial tanks.
- Laser Marking: Provides full traceability and batch tracking.
