Multi‑Material Profile Straightening Machine for Aluminum, Copper, Steel & Brass Tubes and Bars – One Machine for All Your Shaped Metal Needs

Advanced multi‑roll and contour‑matched straightening technology delivers ≤0.2 mm/m straightness on squares, rectangles, hexagons, channels, angles and custom profiles – across aluminum, copper, steel, brass, and their alloys.

The Challenge of Straightening Different Materials on a Single Machine

Workshops and service centers often process a wide variety of materials – from soft aluminum and brass to harder copper and steel – each with different spring‑back, surface sensitivity, and straightening force requirements. Investing in separate straighteners for each material is costly and space‑consuming.

The solution: a versatile profile straightening machine engineered to handle aluminum, copper, steel, and brass tubes and bars – switching between materials with simple recipe changes and quick‑change tooling.

Why a Universal Profile Straightener Is the Smart Choice

Material	Key Challenge	How Our Machine Handles It
Aluminum (6061, 6063, 7075)	Soft, prone to scratching and galling	Polyurethane‑coated rolls; gentle pressure; no marking
Copper (C11000, C12200)	Ductile, high spring‑back	Programmable over‑correction; polished roll surfaces
Steel (carbon, alloy, stainless)	High force required, risk of roll wear	Heavy‑duty frame; hardened steel rolls; higher tonnage
Brass (C36000, C38500)	Moderate hardness, surface sensitivity	Contoured rolls protect corners; adjustable speed for work hardening prevention

Key Features of the Multi‑Material Profile Straightener

• Interchangeable roll sets – One set for aluminum/brass (polyurethane coated), another for steel/copper (hardened polished steel). Change in under 15 minutes.

• CNC servo‑controlled roll positioning – 0.01 mm repeatability for precise pressure tuning per material.

• Closed‑loop laser measurement – Real‑time straightness verification; auto‑adjusts for different spring‑back characteristics.

• Variable speed drive – Slow for work‑hardening‑prone materials (brass, some copper); faster for steel and aluminum.

• Recipe management – Store straightening parameters for hundreds of profiles and material grades.

Shapes You Can Straighten

• Squares and rectangles (solid or hollow)

• Hexagons and octagons

• Channels (U‑shaped, C‑shaped)

• Angles (equal and unequal leg)

• Flat bars

• Custom extruded sections

Industries Served

• Electrical – Copper and aluminum busbars (rectangular bars)

• Plumbing & HVAC – Copper tube, brass fittings, aluminum extrusions

• Automotive & EV – Steel chassis profiles, aluminum battery frame rails, brass valve components

• Aerospace – Aluminum and steel structural stringers

Benefits of a Single Multi‑Material Straightener

• Lower capital investment – One machine instead of two or three

• Reduced floor space – Single footprint for all materials

• Faster changeover – Recipe recall + quick‑change roll sets (15 minutes)

• Consistent quality – Closed‑loop laser feedback ensures same straightness standard across materials

• Simplified maintenance – One machine to service, one spare parts inventory

Automation Options

• Magazine infeed – Load up to 2 tonnes of mixed material bars/tubes

• Exit stacker – Automatically bundles straightened products

• Data logging – Full traceability for ISO/AS9100 audits

Real‑World Example

A European metal service center processing aluminum, brass, and steel profiles (squares, hexagons, channels) previously operated three separate straighteners. After installing a FangRong multi‑material profile straightener with interchangeable roll sets, they:

• Reduced floor space by 60%

• Lowered capital investment by 45%

• Cut changeover time from 90 minutes to 15 minutes

• Achieved ≤0.15 mm/m straightness across all materials
