Shearing / Industrial Knives

Shearing is a cutting process used to separate sheet, plate, film, or extruded materials by applying shear forces through opposing blades. Industrial knives – such as straight, circular, rotary, or guillotine blades – are mounted in shears, slitters, granulators, and recycling equipment. The process relies on controlled blade clearance, cutting angle, and applied force to achieve clean edges and minimize deformation. Typical materials processed include steel, aluminum, copper alloys, plastics, nonwovens, rubber, paper, and composites. Knife materials are selected for wear resistance and toughness, ranging from high‑carbon tool steels and HSS to carbide‑tipped or fully carbide designs for abrasive applications. Tooling includes precision‑ground knives, adjustable holders, spacers, anvils, and hydraulic or mechanical actuation systems. Proper alignment, lubrication, and surface finish of blades are essential to maintain cut quality and reduce downtime. Shearing and industrial knives are used extensively in metal processing, converting lines, packaging, automotive trim cutting, recycling systems, and the production of coils, strips, films, and laminates.
