FAQ
Q: What is the accuracy of rotary die cutting?
A: Typical accuracy is:
±0.1 mm to ±0.3 mm depending on machine grade
High-end servo-controlled machines can achieve very stable registration over long runs.
Q: What is the maximum web width the machine can handle?
A: It depends on model, common ranges:
350 mm / 450 mm / 650 mm / 850 mm / 1050 mm / 1300 mm
Custom machines can go wider for industrial applications.
Q: How many slitting knives can be installed?
A: Usually:
10–50 sets depending on machine width
Some high-end models support quick-change slitting systems.
Q: Can the machine support automatic job changeover?
A: Yes, advanced models support:
Recipe memory (job storage)
Automatic tension and register adjustment
Quick die change systems
Q: How long does it take to change a die cylinder?
A: Typical time:
10–30 minutes (experienced operator)
With quick-lock systems, even faster.
Q: What is the difference between magnetic die and solid die?
A: Magnetic die: Flexible, faster change, lower cost for small/medium runs
Solid steel die: More durable, higher precision, suitable for long runs
Q: What materials are not suitable for rotary die cutting?
A: Very thick rigid boards (better for flatbed die cutting)
Highly elastic materials without proper tension control
Extremely soft films without stabilization
Q: What causes register drift during production?
A: Common reasons:
Film stretching due to tension imbalance
Temperature changes affecting material
Sensor misalignment
Encoder or servo calibration issues
Q: Does the machine require air supply or vacuum system?
A: Yes, many machines require:
Compressed air (for pneumatic systems, waste removal, shaft control)
Some advanced systems also use vacuum for waste stripping.
Q: What is waste matrix removal?
A: Waste matrix removal is the process of stripping excess material after die cutting, leaving only the finished labels or shapes.
Q: Can the machine handle perforation or half-cutting?
A: Yes, rotary die cutting machines can perform:
Full cut
Kiss cut (half cut)
Perforation (tear line cutting)
Q: What is kiss cutting?
A: Kiss cutting means cutting only the top layer (label) without cutting the backing liner, commonly used for sticker labels.
Q: What is the lifespan of a rotary die?
A: Depends on usage:
Steel die: 5–10 million impressions or more
Magnetic die: shorter but replaceable surface tooling
Q: What happens if die pressure is too high?
A: Film deformation
Blade wear increases
Cutting burrs or edge damage
Registration instability
Q: What is the role of servo motors in the machine?
A: Servo motors control:
Web feeding
Registration alignment
Cutting synchronization
They improve precision and reduce mechanical error.
Q: Can the machine integrate with printing lines?
A: Yes, it can be:
Inline with flexo printing
Inline with gravure printing
Offline finishing system
Q: What is the typical machine setup time for a new job?
A: Depending on complexity:
Simple job: 15–30 minutes
Complex multi-lane jobs: 30–60 minutes
Q: What is the most common reason for production downtime?
A: Material breakage
Register sensor issues
Die wear or damage
Slitting blade dullness
Tension instability
Q: Can the machine handle transparent films?
A: Yes, but requires:
High-precision sensors
Proper contrast marks or special registration systems
Q: What is the role of edge guiding system?
A: Edge guiding ensures the material stays aligned laterally during running, preventing misalignment in cutting and slitting.
Q: How is finished product rewound?
A: After cutting and slitting:
Multiple rewind shafts collect finished rolls
Each shaft can be independently tension-controlled
Q: What are key factors when choosing a rotary die cutting machine?
A: Web width requirement
Material types
Required speed (m/min)
Register accuracy needs
Slitting configuration
Automation level
