A slitting circular knife is a type of cutting tool used to cut various materials. It is mainly characterized by circular blades and performs slitting operations on materials by rotating cutting. It has the characteristics of high cutting accuracy, high efficiency, and neat cutting. Its main applications are in the following areas:
1. Paper processing industry
       Printing slitting: In the post-processing of printed materials such as books, magazines, and promotional flyers, a slitting knife is used to cut large format paper sheets into specific sizes of finished products. For example, cutting the printed roll paper into different sizes of flat book pages, or cutting large format poster paper into appropriate sizes for posting and distribution.
       Paper packaging slitting: For enterprises that produce packaging products such as cardboard boxes, paper boxes, etc., a slitting circular knife can slice large format paper into various parts required for packaging production, such as the side panels and cover plates of cardboard boxes, the box body and lid of cardboard boxes, etc.
2. Plastic film processing industry
       Plastic film slitting: In the production process of plastic film, a slitting knife is used to slice the wide plastic film into small rolls of different widths to meet the needs of different customers. For example, cutting wide agricultural films into widths suitable for different crop planting needs, or cutting plastic films for packaging into different specifications for packaging products of different sizes.
       Plastic film bag making: In a plastic bag making factory, a slitting knife cuts the rolled plastic film into appropriate widths, and then performs bag making operations to produce various specifications of plastic bags, such as supermarket shopping bags, garbage bags, freshness bags, etc.
3. Metal processing industry
       Metal strip slitting: For metal strip production enterprises, slitting circular knives are used to cut wide metal strips into narrow strips of different widths to meet the needs of different industries for metal strips. For example, cutting stainless steel strip into narrow strips for making watch straps and decorative strips, or cutting copper strip into specific width strips for electronic component manufacturing.
       Metal sheet cutting: In some metal product processing enterprises, a slitting circular knife can be used to cut thinner metal sheets, cutting large format metal sheets into specific shapes and sizes of components, such as metal sheet cutting in automotive parts manufacturing and sheet cutting in hardware product production.
4. Textile industry
       Fabric slitting: In fabric production and clothing processing enterprises, a slitting round knife is used to cut rolled fabrics into pieces of different widths and lengths for clothing cutting and production. For example, dividing wide cotton and synthetic fabrics into suitable pieces for making different clothing styles can improve the efficiency and accuracy of clothing production.
       Textile strip cutting: For enterprises producing textile strips, such as shoelaces, waistbands, backpack straps, etc., a slitting circular knife can cut wide textile strip blanks into finished strips of different widths and lengths, and then carry out subsequent processing and finishing.
5. Other industries
       Rubber product processing: In the production of rubber products, a slitting knife can be used to cut rubber sheets or rolls into specific sizes and shapes of rubber components, such as rubber seals, rubber gaskets, etc.
       Composite material processing: For some materials composed of multiple materials, such as glass fiber composite materials, carbon fiber composite materials, etc., a slitting round knife can be used to cut them into different specifications of plates or strips, which are used for component manufacturing in aerospace, automotive manufacturing, sports equipment and other fields.
