TSF©: eco-friendly product
The innovative phosphate-free wire drawing (TSF©) technology developed by SEBIR guarantees a greater capacity for geometric definition of headed parts. We minimise the appearance of cracks at 45º and the severity of steel cracks at 90º. And all this with less environmental impact: no phosphate sludge and a 98% reduction in contaminating waste and residue.
TSF© reduces industrial and environmental costs and offers better performance than phosphate coated wire. This method reduces the coefficient of friction during heading while at the same time maintaining lubrication of the wire during extrusion. This means that high-pressure drawn wire enables the manufacture of cold headed parts without using phosphate.
