Fully automated hydraulic drawbenches deliver ±0.02 mm dimensional accuracy, superior surface finish, and consistent mechanical properties for aluminum round, hexagonal, and square bars – ideal for aerospace, automotive, CNC machining, and electrical applications. Why Aluminum Bars Need Specialized Cold Drawing Aluminum bars (6061, 7075, 2024, 6063, etc.) are widely used in precision machining, structural components, and electrical conductors. Cold drawing enhances their prop

From square tubes to hexagonal bars, from asymmetric channels to custom extrusions – achieving ≤0.2 mm/m straightness without edge damage, twist residue, or surface marking. Why Special‑Shaped Profiles Are a Different Straightening Challenge Unlike round bars or tubes, special‑shaped profiles (non‑circular cross‑sections) carry multiple geometric defects simultaneously: Camber – bending in the horizontal plane Bow – bending in the vertical plane Twist – axial rotation along t

Not all straighteners are the same. Here is a practical guide to selecting the right automatic precision straightening machine for your material, profile, and output requirements. Where Do You Start? Walking into a straightening machine purchase without a clear framework often leads to over‑specification (paying for capacity you do not need) or under‑specification (reject rates stay high). Before contacting any supplier, answer these four questions: Question Why It Matters Wh
