How does a slitting machine empower multi-industry production? Inventory of core application scenarios

As the core processing equipment in the industrial field, the slitting machine provides customized material solutions for multiple industries through high-precision cutting and slitting technology, significantly improving production efficiency and product added value. The following is an inventory of its core enabling scenarios and industry applications:

1. New energy industry

1. Lithium battery manufacturing

◦ Application: Slitting pole piece (copper foil/aluminum foil), separator (PE/PP), electrode coating material.

◦ Technical requirements:

▪ Micron-level accuracy (±0.05mm) to avoid short circuits caused by burrs.

▪ Dust-free slitting (cleanroom environment) and tension control (≤2% fluctuation).

◦ Case: "Air float slitting" is required for lithium battery separator slitting to avoid mechanical contact damage.

2. Photovoltaic industry

◦ Application: Slitting of solar backsheet film (PET) and EVA adhesive film.

◦ Technical highlights: Laser slitting avoids thermal stress deformation of conventional tools.

2. Packaging and printing industry

1. Flexible packaging materials

◦ Application: Slitting BOPP, CPP, aluminum-plastic composite film, etc., used in food and pharmaceutical packaging.

◦ Efficiency Improvement:

▪ High-speed slitting (600m/min) with automatic deviation correction system.

▪ Synchronous slitting of multiple tool groups (such as 8~12 in parallel).

2. Label with self-adhesive

◦ Requirements: High-precision slitting (±0.1mm) to ensure accurate die-cutting positioning.

◦ Innovative solution: Circular slitting machine with UV curing to avoid glue sticking.

3. Electronics industry

1. Flexible Circuit Board (FPC)

◦ Application: Slitting polyimide (PI) substrate, conductive adhesive film.

◦ Technical difficulties:

▪ Static control (ionic air bar to remove static electricity).

▪ Tension-free slitting (avoids micro-cracking).

2. Electromagnetic shielding materials

◦ Scenario: Slitted metallized fiber cloth and conductive foam are used for the shielding layer of 5G devices.

Fourth, the automobile industry

1. Interior material processing

◦ Application: slitting leather, non-woven fabric, carbon fiber prepreg.

◦ Special Requirements:

▪ The bevel cutting technology (30°~45°) realizes seamless splicing of the sewing interface.

▪ Anti-contamination slitting (vacuum cleaning device).

2. Battery pack assembly

◦ Example: The slitting of proton exchange membranes in hydrogen fuel cells requires a constant temperature and humidity environment.

5. Medical and sanitary materials

1. Medical non-woven fabrics

◦ Application: Slitting of mask meltblown cloth and surgical gown materials.

◦ Hygienic standard: antibacterial coating on the surface of the equipment, automatic winding and packaging after slitting.

2. Adhesive products

◦ Scenario: Cutting of medical tape and band-aid substrates to avoid glue overflow.

6. Industrial materials

1. Composites

◦ Application: Slitting of carbon fiber and glass fiber reinforced materials, diamond-coated tools are required.

◦ Challenge: Layered control (ultrasonic-assisted slitting).

2. Metal foils

◦ Case: The slitting of ultra-thin copper foil (6μm) adopts closed-loop control of "micro-tension + laser thickness measurement".

7. Emerging fields

1. Wearables

◦ Requirements: Profiled slitting (curve/wavy edge) of flexible sensor materials.

◦ Technology: CNC servo turret with AI visual positioning.

2. Smart home

◦ Application: slitting decorative film (such as 3M film), light guide plate diffusion film.

Empowerment Core Summary

Future Trends

• Intelligent: Integrate IoT sensors for predictive maintenance.

• Green Slitting: Dry slitting technology replaces traditional lubrication and reduces scrap (e.g. ultrasonic slitting).

• Multi-functional integration: slitting-testing-packaging integrated equipment shortens the production chain.

Through continuous technological iteration (such as laser and waterjet slitting replacing mechanical knives), slitting machines are being upgraded from "single cutting tools" to "industry customized solution platforms", becoming an indispensable part of high-end manufacturing.
