Stefa Coil-to-Laser Line CL-300
The Stefa Coil-to-Laser Line CL-300 is a continuous-feed coil processing and laser cutting system for thin, light-gauge sheet metal, suited to high-volume production, steel service centers, automated factories, and prototype work where flexible, automated handling of coil stock is required.
Quick Look
- Application: Coil-fed, continuous laser processing of thin sheet metal for general metal fabrication, light-gauge components, and prototypes.
- Material form: Processes metal directly from coil, reducing manual sheet handling and enabling long, uninterrupted runs.
- Production style: Designed for high-volume, repeatable production in automated factory environments and steel service centers.
- Flexibility: Suitable for both standard production parts and prototype or short-run jobs that benefit from laser cutting’s programmability.
- Automation focus: Integrates coil handling with laser cutting to minimize changeover time and operator intervention.
- Typical users: Metal fabricators, OEMs, and service centers working primarily with thin, light-gauge metals.
Budgeting & Pricing
- Pricing estimate (USD): $900,000 – $2,000,000 USD, depending on configuration, automation level, and options.
- Higher-cost configurations generally reflect added automation (e.g., more advanced coil handling, integrated stacking, or downstream operations).
- Budget should account for installation, commissioning, and operator/maintenance training in addition to purchase price.
- Operating costs are influenced by laser power level, assist gas use, and maintenance of the coil handling and cutting systems.
- For high-volume continuous feed applications, cost justification typically relies on reduced labor per part and improved material utilization from coil.
- Prototype and short-run users should consider the tradeoff between capital cost and the flexibility gained from coil-to-laser processing.
Key Selection Factors
- Coil capacity and material range: Confirm the line is matched to your typical coil widths, weights, and the thin sheet gauges you process.
- Laser cutting capability: Evaluate the laser’s power and cutting performance in the specific thin sheet materials and thicknesses you run most often.
- Throughput requirements: Align line speed, laser cutting speed, and changeover time with your target part volumes and takt times.
- Automation and integration level: Decide how far you want to automate (from coil loading through to finished part offload) and how it will interface with existing factory systems.
- Accuracy and repeatability: Ensure the line’s feeding, guiding, and cutting accuracy meet your dimensional tolerance and edge quality requirements.
- Flexibility for prototypes: Confirm programming workflow and setup time support frequent part changes and prototype iterations without excessive downtime.
- Space and layout constraints: Check that the physical length and footprint of the coil-to-laser line fit your available floor space and material flow.
What to Inspect Before You Buy
- Coil handling system: Inspect decoiler, straightener, and feed mechanisms for smooth operation, robust construction, and suitability for your coil sizes and gauges.
- Laser cutting head and optics: Check condition, cleanliness, and service history of the laser head, lenses, and nozzles, as well as cut quality on representative thin sheet samples.
- Feed accuracy and guiding: Verify that the coil feed and guidance systems maintain consistent alignment and tension to avoid edge waviness or tracking errors.
- Control system and software: Review the HMI, nesting/programming tools, and any integration options with your CAD/CAM and factory systems.
- Safety systems: Confirm guards, light curtains, emergency stops, and interlocks are present, functional, and appropriate for coil-fed laser operation.
- Wear components and maintenance access: Examine rollers, guides, drive elements, and filters, and ensure critical components are accessible for routine service.
- Electrical and pneumatic systems: Assess wiring, cabinets, and air systems for neatness, clear labeling, and compliance with your plant standards.
- Documentation and support: Ensure availability of manuals, schematics, maintenance schedules, and any training or technical support arrangements.
- Test run with your material: When possible, run your own thin-gauge coil material and parts to observe cut quality, line stability, and throughput.
