Reduced-diameter axle tubes and flared tubes

We change the diameter of tubular vehicle parts by cold extrusion, using one-piece forming dies and a reduction (or expansion) process. The accuracy is among the higher levels in the industry, and we make each type of variable-diameter tube to the customer's own requirements.

Reduced-diameter axle tubes are used in drive shafts, tie rods and similar parts. Their service life is verified by balance testing and by torsional fatigue and wear tests; tested torque is above 7000 N·m. Flared tubes are used in mudguard brackets.
