TSF©: an eco-friendly product

We have developed the innovative technology of phosphate-free wire drawing (TSF© – trefilado sin fosfato). This technique enables greater capacity for the geometric definition of cold headed parts. We minimise the appearance of cracks at 45º and the severity of steel cracks at 90º. All this with less environmental impact: no phosphate sludge and a 98% reduction in contaminating waste and residue.
