Custom Circular Slitter Blades for Film, Paper and Nonwoven Cutting

Product Overview

Hengye supplies custom circular slitter blades for film, paper and nonwoven converting equipment. Blade dimensions, steel grade and cutting edge geometry can be specified according to the material being processed and the machine installation.

The product range supports different circular knife configurations, with non-standard specifications reviewed against customer drawings or samples.

Blade Selection for Different Materials

Thin film, adhesive paper and nonwoven fabric place different demands on a cutting edge. Material thickness, adhesive layers and the cutting arrangement should be considered when specifying the blade.

Poor slit quality can be associated with edge wear, unsuitable geometry or incorrect machine settings. Selecting the knife together with the holder arrangement and material specification helps address the cutting requirement more accurately.

Material and Edge Options

Available material families include high carbon steel, high speed steel, tool steel, alloy steel and stainless steel. Listed grades include 65Mn, 9CrSi, Cr12MoV, SKD11 and SKH51. The final grade and heat treatment should be agreed for the application.

Edge configurations can be reviewed for the required cutting method. Specify the bevel profile and working edge position on the drawing, particularly when replacing a blade that has already been resharpened.
