About Drawn-Over Mandrel

DOM mechanical steel tubing is manufactured from electrical resistance welded hollow tubing – further processed by cold drawing through dies and over mandrels – resulting in improved surface finishing, mechanical properties and dimensional accuracy. These characteristics – combined with reliable weld integrity, maximum concentricity, and minimal wall variation – provide a high-quality, cost-effective choice for demanding applications and machined parts.

Typical Applications: Hydraulic Cylinders, Bushings, Motor Housings, Axles, Transmission Shafts, Suspension Components, Fluid Power Applications, and More.
