Custom Serrated Long Blade with 2–20 mm Tooth Pitch for Film, Paper and Nonwoven Cutting

Custom Serrated Long Blade for Film, Paper and Nonwoven Cutting

Hengye Blades manufactures custom serrated long blades for packaging and converting equipment. Blade dimensions, tooth geometry, steel grade and mounting details can be specified to match the machine and the material being processed.

The listed blade configuration measures 150 × 12 × 2 mm (length × width × thickness). Drawing-based customization is available within the listed length range of 50–2000 mm, thickness range of 0.5–10 mm and tooth pitch range of 2–20 mm. These ranges represent customization options rather than the dimensions of one standard blade.

Address Ragged Edges and Incomplete Cuts

Film dragging, paper tearing and uncut fibers can result from worn teeth, unsuitable tooth geometry or incorrect machine settings. Replacing a blade with the same overall length may not resolve the problem if the tooth profile, bevel or mounting position differs.

A serrated edge initiates cutting at individual tooth tips. Matching the tooth pitch and profile to the material, cutting motion and support arrangement helps establish the appropriate blade configuration. Blade alignment, material tension and cutting clearance should also be checked when troubleshooting inconsistent results.

Technical Specifications

Material grades and surface treatments are alternatives. The final combination should be confirmed for the cutting conditions rather than assumed to apply to every blade.

Applications

Packaging Film Cutting

For packaging film separation, trimming and compatible slitting systems, specify the film type, thickness and layer structure. Include details of laminations or adhesives so the tooth profile and surface requirements can be reviewed.

Paper Cutting and Trimming

For paper converting equipment, match the blade length and mounting details to the cutting assembly. Paper grade, coating, thickness and cutting motion should be included when selecting the steel and edge geometry.

Nonwoven and Textile Cutting

Nonwoven fabrics and textiles require the tooth configuration to be reviewed against fiber structure, material thickness and the number of layers. Material support and tension are also relevant when addressing snagging or incomplete separation.

Use in any application depends on the machine design and the approved blade specification.

Select the Blade for Your Equipment

Match the installation dimensions. Confirm length, width, thickness, mounting holes and slots. Include tolerances and reference surfaces on the drawing.

Define the cutting edge. Specify tooth pitch, tooth height, profile and bevel direction. Tooth pitch alone does not fully describe a replacement edge.

Select the material and finish. Provide the existing blade grade where known, along with wear, chipping, corrosion or material-buildup issues. These details help guide material and coating review.

Describe the operating conditions. Identify the material being cut, cutting motion, production frequency and machine model. For replacement orders, include the current blade drawing or sample details.

Frequently Asked Questions

Can you manufacture a blade to our drawing?

Yes. Blade dimensions, tooth geometry, material and surface treatment can be customized according to technical drawings and agreed requirements.

Is 150 × 12 × 2 mm the only available size?

No. It is the configuration currently listed for this product. Custom lengths of 50–2000 mm and thicknesses of 0.5–10 mm are available for review. Specify the required width and mounting details when requesting a quotation.

How should I choose the tooth pitch?

The listed range is 2–20 mm. Selection depends on the material, thickness, cutting motion and required edge result. Provide the existing tooth profile and details of any cutting problems rather than choosing by pitch alone.

Will the blade fit any packaging machine?

No. Compatibility must be checked against the blade holder, mounting pattern, cutting clearance and edge orientation. A machine model or dimensioned drawing is recommended.

What information is needed for a quotation?

Send the blade drawing, required quantity, material being cut, preferred steel grade and surface treatment. Include mounting dimensions, tooth geometry and any specified tolerances.
