Production line and factory setup overview
Manufactures roll-forming roller sets, spacers, shafts and cut-off/support tooling for metal roofing, purlins, studs and sheet profiles through profile/pass design, tool-steel machining, heat treatment, grinding, assembly and trial forming.
Recommended lowest-entry line configuration Start with one roofing, stud or simple channel profile for a named roll-former. Confirm coil thickness and grade, strip width, pass schedule, shaft diameter, station count, forming direction, tolerances, cut-off interface and surface protection before machining rollers.
Production process and implementation sequence
- Target-machine and buyer-drawing review
- CAD/CAM and material/heat-treatment selection
- Cutting, machining, EDM or CNC routing
- Assembly, fitting and surface finishing
- Trial production with target material
- Measurement, functional checks and repeat-cycle inspection
- Packing, documentation and release
Products, capacity and market fit
- Tooling must be designed around the target production machine and released buyer drawing.
- First-off samples, measured dimensions and repeat-cycle evidence must be accepted before production release.
- Start with one high-demand product family and retain tool drawings, settings and maintenance records.
- Roll-forming rollers and tooling - Named roll-former, coil grade/thickness and width, profile drawing, pass schedule, shaft size, station count, tolerance, cut-off and coating protection - Roofing-sheet, purlin, stud, duct and metal-profile producers plus roll-former repair workshops
Core production machinery and line specifications
| Machine / stage | Function / value | Production note |
|---|---|---|
| Profile/pass-design CAD station | Creates forming sequence | Coil/profile match |
| CNC turning/milling cell | Machines roller contours | Pass geometry |
| Heat-treatment service | Protects tool surfaces | Wear life |
| Grinding/shaft assembly bench | Sets concentricity and spacing | Runout/alignment |
| Roll-forming trial station | Checks formed strip | Profile, twist and coating damage |
Raw materials, utilities and factory requirements
- Tool steel, shafts, bearings/spacers, fasteners, heat-treatment service, grinding consumables, gauges, representative coated coil and packing
- Stable three-phase power, guarded machining, calibrated measuring tools, covered material/tool storage and safe lifting/handling
- Documented maintenance, critical wear spares, approved coolants/lubricants and product-specific safety controls
Indicative low-entry investment and implementation plan
These planning ranges prioritize economical machinery, local labor and local civil works. Final pricing follows confirmed capacity, product specification, delivery terms and site conditions.
| Scope | Indicative range | Entry-plan note |
|---|---|---|
| Pass design, CNC turning/milling and rollers | US$25k-100k | One simple profile family |
| Heat treatment, grinding, shafts and gauges | US$12k-50k | Runout and wear control |
| Trial coil, setup and correction | US$6k-25k | Named-machine validation |
| Indicative entry total | US$43k-175k | Roll-forming machine and building excluded |
