HENGLIDA machine knife and blade are typically used for slitting paper, adhesive tapes, cassette tapes, plastic films, and various foils in gold, silver, copper, aluminum, or titanium alloys. Those cutting applications require a high standard of cross cutting or lengthwise shearing performance. Designed to be sharp and resist wear and tear, HENGLIDA slitting blades and straight knives for cutting paper provide smooth cutting operation without causing any drag.
Based on your application needs, blade designers at HENGLIDA would be more than happy to design a proper bevel angle for your knife edge. We produce each and every slitter blade with great attention to details. The blade is carefully polished to cut smoothly, leaving a straight paper edge with no burrs. Upon request, we can produce ultra-sharp lower slitter blades inlaid with hard alloys for your slitter rewinder. The addition of hard alloys to steel blades would drastically increase their wear resistance and reduce the number of times needed for tool maintenance and replacement. Equally noteworthy is our single bevel circular blade, with a maximum diameter of up to 700mm. High-precision grinding machine ensures minimum run-out of the blade.
