Cold Roll Forming

I. Core Process Characteristics

Core: Room-temperature processing. Metal undergoes progressive plastic deformation via well-arranged forming rolls to achieve target cross-sections. Advantages:

Stable material grain structure (no hot-processing performance loss)

Precise cross-sectional dimensions, high surface finish, excellent mechanical properties

Adapts to various materials/thicknesses; supports integrated forming (simple U/C-shapes to complex sections), reducing subsequent processing

II. Core Composition of Production Line

Modular design (flexible configuration per product specs) with core systems:

Uncoiling System: Hydraulic uncoiler + deviation correction device (stable uncoiling, accurate feeding; adapts to different coil widths/thicknesses).

Forming System: Multiple precision rolls (custom contour per profile section) realize progressive bending; precision guaranteed by roll processing and arrangement.

Straightening System: Horizontal-vertical bidirectional straightening eliminates forming stress (ensures profile straightness/flatness for assembly).

Cut-to-Length System: Flying saw/hydraulic cutter + photoelectric length measurement (precise cutting; flat, burr-free surface, less finishing).

Control System: PLC + touch screen HMI (real-time parameter setting, production data recording, fault alarm; efficient operation).

III. Core Product Advantages

High Material Utilization: Continuous forming (negligible raw material loss); 15-30% higher than stamping/welding (cuts costs).

Stable Precision: Digital roll design + precise transmission control (tight dimension tolerance; excellent mass-production consistency, less assembly error).

High Efficiency: Full automation; adjustable forming speed; single-line daily output up to thousands of meters (meets large orders).

Strong Customization: Quick spec switching via roll replacement + parameter adjustment (adapts to multi-variety small-batch demand; shortens R&D cycle).

IV. Main Application Scenarios

Construction/Steel Structures: C/Z-purlins, U-grooves, floor decks, columns (lightweight, high bearing capacity; reduces building weight/cost).

Automotive/Transportation: Frame rails, carriage columns, container profiles, highway guardrails (lightweight via optimized sections; improves impact resistance/lifespan).

Warehousing/Logistics: Shelf columns/beams, pallet supports (load-bearing design; high precision ensures assembly stability/safety).

Agricultural Machinery: Frames, implement racks, guardrails (adapts to harsh conditions; good wear/corrosion resistance with surface treatment).

V. Service and Support

Pre-Sales: Profile optimization, production line configuration, investment return analysis (based on cross-section, material, performance requirements).

In-Sales: Installation, commissioning, roll customization, parameter optimization + operator training (ensures quick production).

After-Sales: 24h technical support, regular maintenance, vulnerable parts supply, on-site process problem-solving.
