High-Precision Rotary Slitting Machine for Industrial Web Converting | Advanced PLC Control System
Industrial Rotary Slitting Machines by Shanghai Honghua Digital Equipment Co., Ltd. are intended for high-speed web conversion. The machine slits at 200 m/min, with a tolerance of ±0.10 mm and is equipped with photo-electric web guiding and PLC based touch screen administration. Our equipment service flexible packaging, label conversion and film processing with 20 years manufacturing expertise and 13 technologies. Each device is quality-tested and comes with a 12-month warranty and lifetime technical support. Unwind diameters up to 650 mm for machines with material widths ranging from 320 mm to 450 mm.
What is a Rotary Slitting Machine?
The tool cuts large master rolls accurately utilising circular rotary blades. Unlike shear cutters, rotary technology retains material in large volume manufacturing.
This device is used to solve severe manufacturing problems. Uneven widths and fraying edges reduce the quality of electronics and packaging. Waste of production materials impacts earnings.
Paper, plastic films, metal foils and technical textiles have clean edges from continuous rotary cutting. More consistent output and fewer downtime means better productivity.
Core Features & Technical Advantages
We use reliable automation in our Rotary Slitting Machines to increase your operational efficiency.
Photoelectric Web Guiding System, automated correction of material variation during unwinding. This provides tracking during the slitting process therefore preventing edge flaws.
PLC Touchscreen Control makes it easy to use with its intuitive interface design. Operators may change settings fast without a long training. The technology monitors speed, tension and cutting accuracy in real time.
Automatic Meter and Piece Counting features accurately monitor production quantities. Preset length settings automatically end, minimising waste and enhancing operational efficiency.
The small integrated structure is roughly 800 KG in weight and stable during high-speed operation. Components that are precision manufactured will give constant performance for 20 years of service life.

Industrial Applications & Use Cases
Laminated films and BOPP substrates used for flexible packaging need neat edges. Our unit handles heat-sensitive materials without thermal distortion by improving tension control.
Precision width tolerance and reduced edge dust optimise label conversion. The photo-electric guide system aligns the pressure sensitive adhesive in the manufacturing process.
High grade film processors for polyester, polypropylene and speciality films. Automatic counting integrates well with downstream packaging equipment.
Good processability for technical textile applications like non-wovens and coated materials. Material thicknesses from 0.01mm to 2mm are adjustable blades.
Less operator engagement and rejection in your production environment Small footprint is compatible with existing floor layouts without facility modifications.
Quality Control & Manufacturing Standards
Each Rotary Slitting Machine is subjected to rigorous testing prior to shipping. Blade run-out tests show that radial and axial deviation are within 0.02mm tolerances.
In our quality processes we do load testing continuously for 72 hours under full production circumstances. Special loadcells are used to check the linearity of tension and to guarantee constant winding density.
Critical components are subjected to ultrasonic defect identification and precise balancing. This removes vibration related quality problems at high speed operation.
ISO 9001 certified processes at manufacturing plants in South China, East China and Southeast Asia. Stringent inspection processes guarantee that each product fulfils established standards.
Our export packing is professional. We utilise fumigated sturdy oak crates with multi-layer shockproof foam. Precision components are individually moisture-proofed for international transport.
Customization & OEM/ODM Services
We provide flexible customisation to meet your individual manufacturing needs. Hardware variants are available for different material kinds and production quantities.
Blade Configuration Options Shear cutting for high gauge material Razor cutting for thin film. Special non-stick coatings are used to eliminate adhesive build-up during PSA processing.
Software Customisation modifies tension profiles and cut sequences to suit the material properties. PLC programming changes enable integration with current production management systems.
Non-Standard Development meets width constraints or specific handling requirements. We work with you along with our engineering team from idea through to commissioning.
Minimum order amounts enable single unit samples and small batch manufacturing. It gives you freedom to verify performance, then scale operations.
FAQ
Q: How do I choose between shear cutting and razor cutting blade systems?
A: Shear cutting provides burr free edges on large gauge foils and thicker materials. Razor cutting may be used for cost-effective processing of thin plastic sheets (< 0.05mm).
Q: Why do completed rolls 'telescope' or become uneven?
A. This is caused by improper tension control. On the PLC interface, configure the taper tension parameters to meet the elasticity properties of the material.
Q: How frequently do rotary blades need to be sharpened or replaced?
A: Inspection intervals vary with the abrasiveness of the substance. Standard blades have to be checked every 100,000 meters. Options for tungsten carbide enhance service life considerably.
Q: Can the machine handle heat-sensitive materials without damage?
A: Sure. High-speed slitting is prevented from thermal distortion by chilled rollers and specific air-cooling systems.
Q: What are the lead times for custom blade configurations?
A: Standard configuration lead times are often 4 weeks. Custom designed spacers and knife holders take 6-8 weeks involving precise balance testing and verification runs.
