Industrial Knives – Manufacturing

Industrial knives are precision cutting tools used in a wide range of manufacturing and processing industries. They are designed for cutting, slitting, separating, trimming and perforating materials such as paper, film, plastics, rubber, textiles, food products and metals.
Depending on the application, industrial knives are manufactured in different designs, including machine knives, circular knives, round knives, shear knives, perforating knives, carbide knives and special cutting blades.
The cutting process may involve shearing, piercing, crushing or perforating, depending on the material and the required cutting result. The geometry and condition of the cutting edge have a direct influence on cutting quality, tool life and production efficiency.
Manufacturing of Industrial Knives
The manufacture of an industrial knife requires careful selection of the material, precise machining and accurate grinding of the cutting edge. Depending on the application, we manufacture industrial knives from materials such as tool steel, high-alloy tool steel, stainless steel, high-speed steel (HSS), HSS PM and carbide.
Material selection depends on several factors, including:

• the material being cut
• the cutting method
• required hardness
• wear resistance
• toughness
• operating conditions
• required service life

For demanding applications, HSS, HSS PM or carbide can provide increased wear resistance and longer service life.
Heat Treatment and Grinding
Heat treatment is an important part of industrial knife manufacturing. The appropriate hardening process gives the knife the required combination of hardness and toughness for its intended application.
After heat treatment, precision grinding is used to achieve the required dimensions and cutting-edge geometry. The cutting angle, edge geometry, flatness and dimensional tolerances can have a significant influence on the performance of the finished knife.
Industrial Knives for Different Applications
Industrial knives are used wherever materials have to be cut accurately and efficiently. Typical 
applications include:

Paper and cardboard processing Packaging production Plastic and film processing Recycling Textile processing Food processing Metal processing Rubber processing Printing and converting

Depending on the machine and application, different knife geometries and cutting principles are required.
Custom Industrial Knives
We manufacture industrial knives and machine knives according to customer drawings, specifications or samples. Custom knife designs can be produced to suit specific machines, cutting processes and materials.
This includes special cutting geometries, circular and round knives, straight machine knives, perforating knives and other customized industrial blades.
Resharpening of Industrial Knives
Many industrial knives can be resharpened several times. Professional grinding restores the cutting edge and can significantly extend the service life of the knife.
Regular inspection and timely resharpening can help maintain consistent cutting performance and reduce the need for frequent replacement.
If you require custom industrial knives, machine knives or precision cutting tools, send us your drawing, sample or technical requirements. We will be happy to discuss the appropriate material, knife geometry and manufacturing solution for your application.
