Slitting machine is a kind of equipment that cuts wide rolls into narrow materials. It is widely used in many industries. The following describes its application scenarios from different fields.

1. Packaging industry

1.1 Project background:

Packaging materials (such as plastic film, paper, aluminum foil, etc.) need to be slit into specific widths to meet the automated packaging needs of food, daily chemicals and other products.

1.2 Solution:

The slitting machine achieves stable slitting of materials of different thicknesses through high-precision tension control and automatic deviation correction system, supporting high-speed production.

1.3 Application case:

A food packaging factory uses a slitting machine to slit wide PE film into narrow rolls for automatic filling of potato chip packaging lines.

1.4 Advantages of slitting machines:

Reduce material waste (accuracy up to ±0.1mm), support a variety of materials (such as BOPP, PET), and improve production efficiency by more than 30%.

1.5 Future development:

Integrate AI algorithms to optimize cutting paths, combine the Internet of Things to monitor equipment status in real time, and achieve predictive maintenance.

2. Printing industry

2.1 Project background:

Printed rolls (labels, posters, etc.) need to be slit into finished product sizes, while maintaining the integrity of the pattern.

2.2 Solution:

Use a visual positioning system to ensure that the cutting line is accurately aligned with the printed pattern, and support variable size slitting.

2.3 Application case:

A label printing company uses a circular knife slitting machine to slit a whole roll of self-adhesive material into customized labels for cosmetic bottles.

2.4 Advantages of slitting machines:

Avoid offset of printed patterns (error <0.05mm), support high-speed slitting (300m/min), and reduce manual re-inspection.

2.5 Future development:

Introduce AI image recognition technology to automatically detect and remove defective products and improve the yield rate.

3. New energy industry

3.1 Project background:

Lithium battery pole pieces (copper foil, aluminum foil) need to be slit into precise widths to meet the requirements of battery cell stacking or winding processes.

3.2 Solution:

Laser slitting technology achieves burr-free cutting of ultra-thin materials (6μm copper foil), and cooperates with a closed-loop dust removal system to ensure cleanliness.

3.3 Application case:

A power battery company uses a slitting machine to process positive aluminum foil, and directly enters the coating process after slitting, which increases production efficiency by 25%.

3.4 Advantages of slitting machine:

Cutting accuracy reaches ±0.03mm, reducing the risk of battery short circuit caused by electrode burrs.

3.5 Future development:

Research and develop composite slitting technology (such as ultrasonic vibration knife) to adapt to new materials such as solid-state battery electrodes.

4. Textile industry

4.1 Project background:

Cloth and non-woven fabrics need to be slit into specific widths for the production of clothing, home textiles or medical supplies (such as masks).

4.2 Solution:

Use air-expanding shaft winding and static elimination device to avoid fabric deformation or adsorption of impurities. Application case: A medical non-woven fabric factory uses a slitting machine to slit meltblown fabrics into 30cm wide rolls to supply mask production lines.

4.3 Advantages of slitting machine:

Supports slitting of elastic materials (such as spandex fabrics), with smooth edges and no loose threads, and a yield rate of 99.5%.

4.4 Future development:

Linked with the intelligent storage system, the rolls can be automatically labeled and stored after slitting.

5. Electronics/Medical

5.1 Project background:

The electronics industry needs to slit optical films (such as OCA films) and screen protective films; the medical industry slits medical tapes and dialysis membranes.

5.2 Solution:

Nano-precision slitting (±0.01mm), equipped with constant temperature and humidity environment control.

5.3 Application case:

An electronics factory uses a slitting machine to slit 0.05mm thick OCA film into narrow strips for mobile phone screen lamination.

5.4 Advantages of slitting machine:

dust-free workshop adaptation to avoid material contamination; ultra-thin material slitting without stretching deformation.

5.5 Future development:

Develop micro-slitting modules, integrate them into flexible electronic production lines, and realize roll-to-roll (R2R) manufacturing.
