About adm-tube
adm-tube is a Berlin family business that manufactures and sells capillary and precision tubes of artisanal quality. The seamless-drawn tubes have outer diameters of 0.20 to 30.00 mm with tolerances down to ± 0.005 mm and lengths of up to 3.50 meters. The materials – aluminium, copper, brass, nickel silver, Monel, bronze and stainless steel – are sourced from German production. The service portfolio also includes burr-free cutting of tubes and metal (tolerance ± 0.10 mm), the manufacture of EDM electrodes in single- and multi-channel designs, and a piece-exact packaging service for small parts. Processes such as annealing, re-drawing, straightening, forming, welding, laser processing and brazing/soldering are carried out in-house or with partner companies. Customers come from, among others, the automotive and music industries, medical technology, aerospace, shipbuilding, mechanical engineering and cryogenics.
