Description
Umprotech Coil-Fed Fiber Laser – 60 in × 0.100 in · 4 kW · 15 t Decoiler
Coil-fed fiber laser blanking line engineered for US job shops, OEMs, and contract fabricators that run 60" coil and need stable, automated blanking up to 0.100" carbon steel. The line integrates 15 t decoiling, precision leveling, servo feeding, and a 4 kW fiber laser cutting cell into one continuous process, transforming coil supply into repeatable blanks with minimal operator intervention.
Positioned in the mid-power class, the 4 kW source provides a comfortable process window for the ≈0.048–0.100" thickness range: fast cutting on thinner gauges, with sufficient power margin at the upper limit to support robust pierce routines, stable kerf, and consistent edge quality.
Coil width: 60 in · Max thickness (rating): up to 0.100 in carbon steel* · Laser power: 4 kW fiber · Decoiler: 15 t nominal capacity
*Thickness rating assumes low-carbon steel within specified mechanical and flatness tolerances. Higher-strength, stainless, galvanized, or coated material may require derated thickness, reduced duty, or dedicated parameter sets verified by test cutting.
Key advantages for US buyers
- Continuous coil-fed workflow: Converts 60" coil directly into blanks, eliminating sheet loading, reducing fork-truck traffic, and stabilizing upstream material flow into downstream bending and welding cells.
- 4 kW cutting power in the right window: Provides strong cutting performance on 0.048–0.100" carbon steel, with sufficient power overhead for stable piercing and production-grade edge quality at the top end of the rating.
- 15 t decoiler for long runs: Supports heavy coils from US service centers, enabling extended unattended runs and fewer coil changeovers on high-demand part families and blanket orders.
- Precision straightener and servo feeder: Integrated multi-roll leveler reduces coil set and crossbow; encoder-based servo feed ensures accurate strip positioning into the cutting zone, which is critical for nesting accuracy and downstream forming performance.
- Production-grade HMI with nesting/CAD import: Imports standard CAD formats (e.g. DXF) and generates nests tuned to coil width, part mix, and scrap strategy, shortening setup time and improving material yield per coil.
- Scalable automation: Optional automatic stacker, zone-based part sorting, barcode/etch marking, and fume extraction let you configure the line for anything from supervised shifts to lights-out operation.
Key technical specifications
Coil / working width: up to 60 in
Processes coil stock up to 60" wide, allowing one-up blanks for large panels or multi-up nests of smaller parts. Matches common 48–60" coil standards supplied for HVAC, enclosure, and general fabrication workloads in North America.
Thickness range (carbon steel): up to 0.100 in (≈2.5 mm)
Typical process window covers ≈0.048–0.100" low-carbon sheet. Below this range, coil handling and line dynamics may favor thin-gauge-optimized configurations; near 0.100", cutting becomes more power- and quality-sensitive and should use validated parameter sets and assist gas strategies.
Laser source: 4 kW fiber
High-efficiency fiber source with stable output for continuous-duty blanking in this thickness range. Supports O₂ and N₂ cutting (and shop-air cutting where supported) to balance cut speed, edge quality, oxidation, and operating cost by part family.
Cutting head: Autofocus fiber head with collision protection
Programmable focus and Z-heights for pierce and cut, with capacitive height sensing for maintaining kerf and edge quality over long runs. Collision-protection design helps safeguard optics and mechanics in the event of strip lift, skeleton movement, or edge catch.
Decoiler capacity: up to 15 t
Heavy-duty decoiler sized for typical 60" coil packages in this gauge range. Designed to manage coil mass, braking, and uncoiling forces while maintaining controlled strip payout into the leveler.
Straightener / leveler: precision multi-roll configuration
Reduces coil memory and residual stresses prior to cutting. Proper setup of roll penetration and tension is critical for flat blanks and consistent behavior in downstream bending, forming, and welding.
Servo feeder: encoder-based closed-loop feed
Controls strip indexing into the cutting cell with accurate feed-length control and minimal slippage. Supports tight blank length tolerance and repeatable nest positioning across full coil runs.
Material handling & scrap: integrated strip path and scrap evacuation
Includes entry peeler, feed unit, cutting zone, and conveyor-based scrap/skeleton removal. Scrap is designed around continuous coil operation, avoiding manual skeleton handling typical of sheet-fed lasers.
Controls & software: HMI with nesting / CAD import
Operator interface manages coil, material, and job libraries. Nesting engine optimizes layouts for coil width and part mix, with job queues and operator prompts suited for high-mix production.
Engineering view: process window & line sizing
The 60 in × 0.100 in, 4 kW, 15 t coil-fed configuration targets shops that want coil-based efficiency in the mid-gauge window without stepping into very heavy plate handling or higher-power laser classes. Correctly sizing the coil, leveler, feeder, and cutting parameters is essential to realizing the expected throughput and edge quality.
Typical coil thickness window (illustrative): ≈ 0.048–0.100 in
Within this window, 4 kW provides a comfortable margin for pierce routines and cut speeds, particularly with oxygen cutting on thicker material and nitrogen or air on thinner gauges. Outside this window, process capability and economics must be evaluated case by case.
Coil ID / OD (example ranges):
Typical coil ID: ≈20–24" · Max OD: ≈60–72"
Actual values depend on the specific decoiler mandrel design and must be aligned with your
service-center coil specs during the engineering review.
Behavior at upper thickness limit (≈0.100"):
At the top end of the rating, the process is more sensitive to material batch, flatness, and coating conditions. Cut speeds and pierce conditions become more conservative, skeleton design must limit strip motion, and assist gas selection (O₂ vs N₂) is typically driven by a tradeoff between throughput and weld-ready edge quality. Application-specific test cutting is strongly recommended for critical parts.
Capabilities & typical applications
This 60 in × 0.100 in, 4 kW coil-fed fiber laser line is intended as a core blanking platform for operations that already consume 60" coil or plan to transition from sheet-based supply to coil-based logistics for mid-gauge steel.
- Blanking of panels, doors, cover plates, and frames directly from 60" coil.
- Production of brackets, rails, and formed profiles that demand consistent flatness for downstream forming.
- Supply of cut-to-size blanks into press brakes, panel benders, turret punches, or robotic welding cells.
- High-mix/low-volume or repeat production for OEMs and contract manufacturers using standardized coil specs.
- Industries including metal fabrication, HVAC, appliance, machinery, electrical enclosures, and general manufacturing.
Implementation & support for US shops
Umprotech partners with US fabricators and OEMs from the initial sizing discussion through commissioning to ensure that the 60 in × 0.100 in, 4 kW, 15 t coil-fed line is correctly specified, installed, and integrated into your material flow and downstream processes.
- Pre-installation review: floor loading and pit requirements (if any), coil storage and crane/fork access, power, fume extraction, guarding, and safety zoning around the coil and cutting areas.
- Application engineering: assessment of coil specs (width, ID/OD, thickness range, grades, coatings), part families, nesting strategies, and cycle-time modeling to support ROI and capacity planning.
- Commissioning & training: on-site installation, parameter tuning for your primary materials, and operator training on HMI, nesting workflow, coil handling, and routine maintenance tasks.
- Ongoing support: assistance adding new materials and part families, optimizing nests, and adjusting run strategies as product mix and volume change over time.
Next step: send your typical coil specifications (width, thickness range, ID/OD, grades/coatings) and representative part drawings or nests (DXF/STEP/PDF). Our engineering team will confirm technical fit, estimate cycle times, and recommend a line configuration that aligns with your throughput, labor, and integration objectives.
