Fully integrated infeed and outfeed systems with magazine storage, singulation, and stacking – eliminating manual handling, reducing labor costs, and ensuring consistent straightening quality for tubes, bars, and profiles.
Why Automate Material Loading and Unloading?
Manual loading and unloading of tubes, bars, or profiles into a straightening machine introduces several inefficiencies and risks:
Labor dependency – dedicated operators are needed to feed and remove material.
Inconsistent feeding – misaligned material can enter the straightener at an angle, causing uneven straightening or roll damage.
Surface damage – manual handling can scratch or dent soft materials (aluminum, copper, brass).
Slow cycle times – loading and unloading often take longer than the straightening process itself.
Safety risks – operators are exposed to moving rolls and pinch points during manual feeding.
FangRong’s automatic loading and unloading material racks solve these problems by integrating magazine‑style infeed, singulation, orientation correction, and exit stacking – all controlled by the straightener’s PLC.
The Complete System – Infeed Rack + Straightener + Outfeed Rack
Component | Function | Automation Feature |
Infeed magazine rack | Stores raw material (tubes, bars, profiles) – capacity up to 2 tonnes | Auto‑singulation – feeds one piece at a time |
Orientation correction (optional) | Rotates square, hexagonal, or flat profiles to the correct entry angle | Optical sensors detect rotation; servo‑driven rotator corrects alignment |
Precision straightener | Corrects camber, bow, and twist – achieves ≤0.15 mm/m straightness | In‑line laser feedback – auto roll adjustment |
Outfeed stacking rack | Collects straightened material in neat, aligned bundles | Stacking fingers – guided drop for damage‑free collection |
Centralized PLC control | Coordinates infeed, straightening, and outfeed speeds | One operator manages the entire line |
How the Automatic Loading & Unloading System Works – Step‑by‑Step
Loading the magazine – An operator (or forklift) places a bundle of tubes/bars onto the infeed rack. The rack holds up to 2 tonnes of material.
Singulation – A separating mechanism lifts one piece at a time and places it onto the infeed rollers.
Orientation check (for profiles) – Laser or optical sensors detect the rotation of square, hexagonal, or flat bars. If misaligned, a servo‑driven rotator corrects the orientation.
Infeed to straightener – Rollers or conveyor belts guide the material into the straightener at the correct speed – synchronized with the straightening process.
Straightening – The material passes through the straightener; closed‑loop laser feedback ensures straightness is within tolerance.
Outfeed to stacker – Straightened material exits onto the outfeed rack. Stacking fingers or guides align the pieces into neat bundles.
Bundle removal – Once a bundle reaches the desired count, the operator removes it – or a conveyor moves it to the next process (cutting, packaging, etc.).
All steps are automated – the operator only loads the magazine and removes finished bundles.

Key Benefits of Automated Loading & Unloading
Benefit | Before (Manual) | After (Automatic Racks) |
Operators per shift | 2 (one loading, one unloading) | 1 (supervises the line) |
Loading cycle time | 15–30 seconds per piece | 3–8 seconds per piece |
Surface damage risk | High (manual handling) | Negligible (guided rollers) |
Straightening consistency | Variable (misalignment) | Consistent (pre‑oriented entry) |
Safety incidents | Risk of hand/arm injury | Zero (operator is outside the guarded zone) |
Scrap from handling | 1–2% | <0.2% |
Optional Upgrades for the Material Racks
Automatic centering – Adjustable side guides center the material before it enters the straightener.
Multi‑lane infeed – Load different sizes or shapes in separate lanes; switch with recipe recall.
Bundling and strapping station – Automatically straps finished bundles for direct shipment.
Integration with cutting line – Straightened material is fed directly into a cut‑to‑length saw – no intermediate handling.
Why Choose FangRong for Automated Loading & Unloading Racks?
26 years of material handling experience – Designed specifically for straightening machines.
Custom rack sizing – We design racks to match your material length, diameter/width, and floor space.
Surface protection – Roller coatings and guided drop mechanisms prevent scratches on soft alloys.

Real‑World Example – Aluminum Tube Straightening with Automatic Racks
A manufacturer of aluminum tubes (6061, 25 mm OD, 6 m lengths) previously used manual loading and unloading – requiring two operators and causing a bottleneck.
After installing FangRong’s automatic infeed and outfeed racks:
Labor – reduced from 2 operators to 1.
Throughput – increased from 120 pieces per shift to 280 pieces per shift.
Surface damage – eliminated (scratches from manual handling dropped to 0%).
Straightness consistency – improved (pre‑oriented entry eliminated misalignment).
Payback period – 9 months.
Conclusion – Automate the Handling, Unlock the Straightener’s Full Potential
A precision straightening machine can only be as productive as its material handling system allows. With FangRong’s automatic loading and unloading racks, you eliminate bottlenecks, reduce labor, and protect your material – all while achieving consistent ≤0.15 mm/m straightness.
