100–500 mm Serrated Long Blade with 2–10 mm Tooth Pitch for Packaging and Paper Cutting

Custom Serrated Long Blade for Packaging and Paper Cutting

Hengye manufactures straight serrated industrial blades to drawing for cutting and trimming applications. This range covers custom lengths of 100–500 mm and tooth pitches of 2–10 mm. The listed configuration has a 50 mm width and 3 mm thickness; final dimensions, tooth geometry and mounting holes must be specified for your machine.

Match the Tooth Profile to the Cutting Task

Incomplete separation, snagging or ragged edges can result from worn teeth, unsuitable tooth spacing or poor material support. A serrated edge initiates the cut at individual tooth tips. The appropriate pitch and profile depend on material thickness, feed conditions and the cutting motion. Confirm these details before replacing an existing knife; changing the blade alone will not correct holder misalignment or incorrect machine setup.

Technical Specifications

Application and Material Selection

Typical applications include packaging material separation, paper converting and textile cutting where a serrated knife is specified by the equipment design. Steel grade, surface treatment and tooth shape should be selected together. Provide details of moisture exposure, abrasion, cutting frequency and any cleaning process so that the proposed specification can be reviewed for your operating conditions.

Information Needed for a Replacement Blade

• Overall length, width and thickness, with required tolerances.
• Tooth pitch, tooth height, profile and bevel orientation.
• Hole diameter, hole spacing, slots and mounting reference surfaces.
• Material being cut, cutting motion, machine model and existing blade grade.

Frequently Asked Questions

Is this a universal replacement knife?

No. Match the holder, mounting pattern, cutting clearance and tooth profile to your equipment before ordering.

Are all dimensions in the table supplied together?

The 50 mm width and 3 mm thickness describe the listed configuration. Length, tooth pitch and custom thickness ranges are options, not one finished blade size. Submit a drawing to establish the exact configuration.

Can I order a different tooth profile?

Drawing-based customization is available. Send your profile drawing or existing blade details, material requirements and quantity for specification review and quotation.
