Triangular capillaries

Triangular capillaries with thin walls are manufactured using our special redrawing technique for profile tubes. Very thin wall thicknesses from 0.1 mm to 0.4 mm can be achieved with direct forming. The capillaries have rounded edges and their size can be adapted to customer requirements.
