Precision Perforation Knives & Perforating Knives Manufacturer

Precision Tooth-Pitch Control and High-Precision Grinding for Consistent Perforation and Easy-Tear Cutting

Perforation knives, also known as perforating or tear-line knives, are commonly used machine knives in automated processing lines. By controlling tooth arrangement, tooth pitch, and cut-to-gap ratios, they create precise perforation patterns that allow materials to remain connected during processing and separate cleanly along the predefined tear line when used. Huang-Qi specializes in perforation knife manufacturing and custom perforating knives, with customized production based on material characteristics, tooth pitch, knife type, blade angle, and machine specifications. This allows the knives to better match actual processing conditions while reducing uneven perforation, pulling, burrs, and unstable cutting performance.

Huang-Qi is a professional Taiwan industrial knife manufacturer, providing a wide range of perforation knives, perforating knives, machine knives, and industrial cutting tools. We also provide custom cutting tools for packaging, paper, film, plastic, rubber, and other material processing applications.

Our perforation knives are widely used for tear-line processing in continuous forms, invoices, tissue rolls, medical patches, plastic bags, and label materials. From tooth profile design and tooth-pitch control to material selection and precision machining, our custom machine knives can be developed according to the customer's actual equipment and processing conditions.

For different perforation lengths, cut-to-gap ratios, and easy-tear requirements, we can also design and manufacture knives based on drawings, samples, and equipment specifications, helping maintain consistent perforation performance during continuous processing and high-speed operation.

Selected Knife Materials & Precision Tooth Processing

We select suitable blade materials based on the operating environment, processing materials, and cutting conditions. Common materials include SKD-11 tool steel, SKH high-speed steel, SUS420 / SUS440 stainless steel, and carbide. Combined with precision machining, grinding, and heat treatment, these processes help provide wear resistance, edge stability, and consistent service life.

Key Advantages

Precise Tooth Pitch for Clean, Consistent Perforation

Precise control of tooth profile, tooth pitch, and cut-to-gap ratio enables stable cutting into the material, reducing pulling, burrs, and uneven perforation for consistent perforation and easy-tear performance.

Multiple Knife Types with Custom Specifications

Available in flat, circular, and special knife configurations, with custom cutting tool designs based on material characteristics, processing methods, and machine structure. Suitable knife materials can also be selected according to actual operating conditions to meet different perforation requirements.

Custom Perforation Knives for Your Equipment & Processing Requirements

In addition to standard-size perforation knives, Huang-Qi provides comprehensive custom cutting tool manufacturing and machine knife design services.

Whether you need to adjust the tooth-pitch ratio for film, paper, plastic, or other materials, or develop perforation knives with special tooth profiles, simply provide your drawings, samples, or equipment specifications. Our technical team will help determine the appropriate knife specifications based on your actual processing requirements.
