Upcast Technology
Our wire starts as oxygen-free rod cast by upcast — upward continuous casting — in our own plant.
01 Process
How upcast works
Melting
Copper is melted in an induction furnace and held under a protective cover, so it picks up almost no oxygen.
Casting
Water-cooled dies dip into the melt; the copper solidifies inside them.
Withdrawal
Rolls pull the solid rod upward, continuously, several strands at a time.
Coiling & drawing
The Ø 8 mm rod is coiled, then drawn and annealed in-house into wire.
02 Benefits
Why it matters
OXYGEN
Oxygen-free straight from casting — an independent laboratory measured 1.1 ppm oxygen in a sample of our wire (July 2026).
SURFACE
Clean, bright surface and uniform structure for reliable drawing and annealing.
CONSISTENCY
Consistent chemistry, lot after lot — documented by a test report for each lot.
