What Are Carbide Strips for Paper and Textile Cutting?

Carbide strips are a very hard and durable material. Due to their sharpness and wear resistance, these strips are commonly used in various cutting applications, including the production of paper products, like Book binding, publishing and textiles. They are able to cut through various materials with precision and efficiency. 

** Application: 

Carbide strips are used in several types of machines for cutting applications in various industries. Here are some specific types of machines that utilize carbide strips:

Rotary Cutting Machines: These machines are commonly used in the textile and paper industries for continuous cutting of materials. The carbide strips provide sharp, durable edges for precise cuts.

Shear Cutters: These machines use carbide strips to perform shear-cutting operations, ideal for cutting thick layers of fabric or paper.

Slitters: Slitting machines use carbide strips to cut wide rolls of material into narrower strips, commonly used in both paper and textile processing.

Die-Cutting Machines: These machines often rely on carbide strips for creating precise shapes and patterns in various materials, including paper and fabrics.

Guillotine Cutters: These cutters can utilize carbide strips for high-precision straight cuts in large sheets of materials, ensuring clean edges, like paper trimmers.

Laminating Machines: In some cases, carbide strips are used in machines that laminate materials, providing the cutting edge needed to trim excess material.

Packaging Machines: These machines may use carbide strips to cut packaging materials efficiently during the packing process.

**Advantages

Using carbide strips for cutting offers several advantages over other materials, such as steel or HSS (high-speed steel). Here are the key benefits:

Durability: Carbide flat strips are significantly harder than steel, which means they resist wear and tear much better. This longevity translates to fewer tool changes and reduced downtime. No distortion even after re-sharpening for excellent cut quality.

Sharpness Retention: Carbide maintains its sharp edge longer than other materials, preventing scratch lines caused by edge chipping, resulting in cleaner cuts and less frequent sharpening.

Precision: Carbide square bars are manufactured to high tolerances, ensuring consistent and accurate cuts, which is crucial in applications requiring precision.

Heat Resistance: Carbide can withstand higher temperatures without losing its hardness, making it suitable for high-speed cutting applications where heat generation is a concern.

Reduced Friction: The smooth surface of carbide strips minimizes friction during cutting, leading to less energy consumption and improved efficiency.

Versatility: Carbide strips can be used in a wide range of applications, from textiles to paper and plastics, making them a versatile choice for various industries.

Improved Surface Finish: The sharpness and stability of carbide strips contribute to a better surface finish on cut materials, enhancing the quality of the final product. For paper cutting, we need a burr-free, very beautiful cutting edge. The tungsten carbide knife made from tungsten carbide strips blank is an ideal choice. 

**Size

The size of the carbide flat bar used for paper and textile cutting can vary depending on the specific application and the type of machine being used. However, here are some common dimensions:

Length: Typically ranges from 200 mm to 2700 mm (approximately 8 inches to 106 inches).

ZZbetter can produce carbide flat strips blank and tungsten carbide guillotine knife with a length of 2700mm, which is the max length at this moment.

Width:  around 10 mm to 50 mm (approximately 0.4 inches to 2 inches), but this can vary based on the cutting requirements.

Thickness: The thickness of carbide strips usually falls between 1 mm and 5 mm (approximately 0.04 inches to 0.2 inches), providing the necessary rigidity for cutting tasks.

Custom Sizes: ZZbetter offer custom sizes to meet specific needs, allowing for tailored solutions in various cutting applications.
