Key Features

Rigid Gantry Frame:

Built from 50 mm stress-relieved steel plates, minimizing vibration and maintaining tool parallelism at speeds up to 250 m/min.

Closed-Loop Tension Control:

Ultrasonic sensors paired with magnetic particle/servo brakes maintain constant web tension (±1 N) across film, foil, and adhesive substrates.

Quick-Change Magnetic Cylinder:

Hardened alloy steel cylinders (HRC 60-62) with ground journals ensure runout of less than 0.003 mm, extending flexible die lifespan.

Closed-Loop Register Control:

High-resolution optical print mark registration sensors correct phase errors dynamically without stopping production.

Waste Matrix Stripping:

Adjustable stripping angles and independent rewind shafts prevent web breakage during high-speed matrix removal.

Applications

Medical & Healthcare: Transdermal patches, wound dressings, diagnostic test strips, and multilayer breathable tapes.

Electronics & EV: Lithium-ion battery components (separators, insulation gaskets), graphite sheets, conductive foam, and optical clear adhesives (OCA).

Industrial & Packaging: High-performance adhesive tapes, abrasive pads, RFID labels, and EMI shielding gaskets.

Configuration & Customization

Machinery is built to order based on specific substrate profiles and downstream integration requirements. Available modular stations include:

Unwind & Splice Unit: Automatic zero-speed or flying splice options for continuous operation.

Lamination Station: Pre-die-cutting or post-die-cutting multi-layer adhesive lamination.

Slitting & Sheeting: Rotary shear, razor, or crush slitting modules integrated inline.

Vision Inspection: 100% inline camera defect detection with automatic rejection gate.

Tooling Compatibility Note: Upper and lower die stations feature universal gear box designs compatible with global standard magnetic cylinder sleeves and solid rotary dies (including standard 1/8" and metric pitch configurations, matching RotoMetrics and equivalent tooling footprints).

Quality Control & Manufacturing

Internal Machining:

Frame plates and cylinder housings are milled on 5-axis CNC machining centers in-house, holding positional tolerances within 0.01 mm.

Dynamic Balancing:

All rotating cylinders and guide rollers undergo G2.5 dynamic balancing to eliminate high-speed vibration.

Factory Acceptance Testing (FAT):

Every machine undergoes a 72-hour continuous dry-run test and a 4-hour live material trial matching the client's sample substrate before crating.

Traceability:

Key electrical components (Siemens, Schneider) and bearings (NSK, SKF) carry full manufacturer origin certificates.

Installation & Technical Support

Documentation: Supplied with complete mechanical assembly drawings, electrical schematics, PLC source code access, and spare parts lists.

Commissioning: On-site installation, laser alignment, and operator training executed by senior mechanical engineers.

Remote Diagnostics: Integrated Ethernet gateway allows secure remote PLC program updates and parameter optimization by our engineering team.

Spare Parts Availability: Standard wear items (pneumatic cylinders, bearings, drive belts) stocked locally for 48-hour dispatch.

Frequently Asked Questions

Q: What is the maximum thickness of material this machine can process?

A: Standard configurations handle web thicknesses from 0.01 mm up to 3.0 mm, depending on the shear resistance and density of the material. Heavy-duty frames can be specified for thicker rubber or foam substrates.

Q: Can this machine switch between solid steel dies and magnetic dies?

A: Yes. The upper die station utilizes universal gear boxes compatible with both solid rotary dies and magnetic cylinder sleeves. Changeover time between tooling types averages 15 to 20 minutes.

Q: How is register accuracy maintained during speed acceleration?

A: The machine utilizes closed-loop servo registration linked to an optical mark reader. The PLC dynamically adjusts the cylinder phase angle relative to the web feed whenever a drift exceeding 0.02 mm is detected.

Q: What is the standard lead time from order confirmation to shipment?

A: Standard single-station rotary die cutters require 60 to 75 days. Fully customized multi-station converting lines with inline lamination and vision inspection require 90 to 120 days.

Q: Do you provide tooling along with the machine?

A: We supply trial magnetic cylinders and test dies based on your drawings. For production tooling, we partner with certified global tooling fabricators or can machine custom gears to match your existing tool inventory.

Q: What utility requirements are needed on the factory floor?

A: Standard requirements include 3-phase 380V/480V, 50/60Hz power supply, and a clean, dry compressed air supply at 0.6 MPa (6 bar) with a flow rate of 300 L/min.
