Description
Umprotech Coil-Fed Fiber Laser Line – 60 in × 0.135 in · 4 kW · 15 t Decoiler
Coil-fed fiber laser blanking system engineered for US job shops, OEMs, and fabrication cells that need to convert 60" coil directly into blanks and finished profiles up to 0.135" carbon steel. The line integrates a 15 t decoiler, precision straightener, servo feeder, and 4 kW fiber laser into one continuous process, replacing manual sheet handling with stable, repeatable coil-to-part automation.
This configuration is targeted at operations where material yield, nested part flow, and minimized touch time are as important as cutting speed—making it a strong fit for plants looking to couple coil-based supply with downstream forming, welding, or assembly cells.
Coil width: 60 in · Max thickness (rating): up to 0.135 in carbon steel* · Laser power: 4 kW fiber · Decoiler: 15 t nominal capacity
*Max thickness rating assumes low-carbon steel within specified mechanical and flatness tolerances. High-strength, stainless, galvanized, or coated material typically requires derated thickness and/or reduced cutting speed, confirmed by test cutting on the configured line.
Key advantages for US buyers
- True coil-to-part automation: Continuous coil-fed operation replaces manual sheet loading, stabilizes material flow into the laser cell, and lets upstream coil logistics drive high-throughput blanking with reduced forklift and crane activity.
- 60" × 0.135" process window: Handles coil up to 60" wide and rated up to 0.135" carbon steel, covering a large portion of light-to-medium plate and structural sheet work common in HVAC, enclosures, machinery, and general fabrication.
- 4 kW fiber laser with autofocus head: Provides the power needed to cut mid-gauge materials while maintaining controllable pierce routines and edge quality at the upper thickness limit when combined with correct assist gas and nesting strategy.
- 15 t decoiler + precision straightener: Heavy-duty decoiler and multi-roll leveler mitigate coil set and crossbow, providing flat, stable strip before it reaches the cutting cell—critical for both cutting accuracy and downstream forming.
- Servo feeder and conveyor scrap removal: Encoder-based servo feed ensures accurate index lengths and stable nest positioning, while automated scrap and skeleton handling keeps the cutting cell clear without manual intervention.
- Production-grade HMI with nesting/CAD import: Imports standard CAD (e.g. DXF) and generates coil-optimized nests to maximize yield, simplify job setup, and support rapid changeovers in high-mix contract or OEM environments.
- Scalable automation path: Optional automatic stacker, zone-based part sorting, barcode/etching, and fume extraction allow the same core line to support everything from staffed shifts to lights-out blanking cells.
Key technical specifications
Coil / working width: up to 60 in
Supports common 48–60" coil widths supplied by US service centers. Allows one-up large blanks, multi-up layouts of smaller parts, and coil-width-optimized nests to drive high material utilization.
Max thickness (carbon steel): up to 0.135 in (≈3.4 mm)
Rated for low-carbon steel up to 0.135" under specified material and flatness conditions. Within roughly 0.060–0.135", process performance is governed by validated parameters, assist gas strategy, and strip stability. HSLA, stainless, galvanized, or painted materials typically require a lower effective max thickness and/or reduced cutting speeds.
Laser source: 4 kW fiber
High-efficiency fiber source suitable for continuous-duty blanking in this thickness window. Supports O₂ and N₂ cutting (and air where supported) for different priorities: speed vs edge oxidation, weld-ready edges vs gas cost, etc. Power and duty cycle are sized for coil-fed, production-grade use, not prototype-only work.
Cutting head: Autofocus fiber head with height sensing
Programmable focus position and stand-off, with capacitive height control for consistent kerf and edge quality across the usable field. Collision-protection design helps protect optics and mechanics from strip lift, skeleton movement, or part upforms.
Decoiler capacity: up to 15 t
Handles large coil packages for extended runs and fewer changeovers. Braking and drive are sized to manage the inertia and payout forces associated with 15 t coil loads at this gauge range.
Straightener / leveler: precision multi-roll configuration
Reduces coil memory, crossbow, and edge wave prior to cutting. Correct roll penetration and tension settings are essential for flat blanks, stable cutting, and predictable behavior in downstream bending and welding applications—especially above 0.100".
Servo feeder: encoder-based closed-loop feed
Controls strip index length into the cutting cell with minimal slippage. Enables accurate blank length, nest alignment, and repeatable performance across the full coil, including at high duty cycles and tighter tolerance requirements.
Material handling & scrap: conveyor-based scrap and skeleton removal
Scrap and skeletons are evacuated via conveyor, minimizing manual scrap handling and keeping the cutting area clear during continuous coil operation. Scrap management is tuned to coil-fed production, not sheet-by-sheet loading.
Controls: HMI with nesting / CAD import
Operator interface manages coil, material, and job libraries. Nesting software optimizes part layouts for 60" coil width, part mix, and scrap strategy. Job queues and operator prompts support high-mix, multi-shift environments where multiple part families share the same coil specs.
Options: automation & safety
Automatic stacker, zone-based part sorting, IPG/MAX/Raycus source selection, inline barcode/etching, and fume extraction packages allow tailoring of automation level, traceability, and air quality to each facility's requirements.
Engineering view: process window & application limits
A 60 in × 0.135 in, 4 kW coil-fed line sits at the intersection of mid-gauge coil handling and mid-power fiber laser capability. At this combination, throughput and edge quality are highly dependent on material selection, nesting strategy, and cut parameter tuning—especially as parts approach the 0.135" thickness limit.
Illustrative working thickness window: ≈0.060–0.135 in carbon steel
Below ≈0.060", the line behaves like a high-speed sheet system, often limited by motion and pierce sequences rather than power. From ≈0.095–0.135", the process becomes more sensitive to batch variation, coatings, and edge-quality expectations; this zone must be validated against your actual material mix.
Material considerations at 0.135":
For 0.135" low-carbon steel, cut speeds and pierce routines must be somewhat conservative to maintain quality and stability. For HSLA, structural grades, stainless, or pre-painted coils, the effective thickness window and throughput will be lower; these applications require test cutting and may be more appropriate in a derated thickness range or higher-power configuration.
Coil & logistics interface:
Typical coil ID is ≈20–24" with max OD in the ≈60–72" range (exact limits depend on the configured decoiler). Coil handling (crane/forklift, cars, storage) and line pit/foundation requirements should be reviewed early in the project, as they often drive both feasibility and installation sequencing.
Capabilities & typical applications
The Umprotech 60 in × 0.135 in, 4 kW coil-fed fiber laser line is intended as a high-throughput blanking and part-production cell that feeds directly into downstream forming, welding, or assembly operations.
