TUBES

Our tubes are mainly made with continuous casting, after which they are hammered to shape and hardened all the way throughout the piece. A high-quality product is guaranteed for every possible application, ranging from jewellery, watchmaking or industrial applications such as medical and automotive.

TUBES FOR LUNETTE

Large diameter tubes, calibrated for threading and with specific physical properties thanks to sophisticated machining procedures accompanied by controlled thermal treatments.

MOLDED TUBES

Moulded tubes are generally used by threaders to make special fittings for bracelets, clasps or buttons. Moulded tubes are widely used even for jewellery.
