Tear Notch Blades for Packaging

What are tear notch blades?

Tear notches, also known as serrations or sawteeth, are indentations or grooves made on the blade's edge to create a saw-like effect. They are typically found on the cutting edge of a knife or tool and are designed to help the blade cut through materials that would be difficult to slice with a smooth, straight edge.

Notches can be made in various shapes and sizes, depending on the intended use of the blade. For example, a blade with fine, closely spaced notches might be used for slicing through soft materials like bread or cheese, while a blade with larger, more widely spaced notches might be used for cutting through more rigid materials like rope or wood.

Tear notches blades are one of the most common blades used in food processing such as bakery, poultry, meat processing, packaging, and many other industrial uses. They are typically made from high-carbon steel and are very hard and durable.

Baucor manufactures and supplies both standard and custom size tear notch knives and blades for all kinds of use including food processing such bakery, poultry, meat processing and packaging as well as many other industrial uses. Regardless of industry, our tear notch knives and blades are made from quality ground hardened tool steels, stainless steel as well as tungsten carbide.

Advantages of using tear notches blades

There are many advantages of using tear notches blades:

  • Improved cutting performance:
    Notches can help the blade more effectively cut through materials that would be difficult to slice with a smooth, straight edge. It can be beneficial for cutting through tough or fibrous materials.

  • Less resistance:
    Notched blades require less force to cut through materials, making them easier to use and less tiring for the user.

  • Durability:
    Notches can help extend the blade's life by preventing it from becoming excessively worn or damaged. Because the notches do the majority of the cutting work, the smooth portion of the blade is less likely to become dull or damaged.

  • Increased tool versatility:
    Blades with notches can be used for a broader range of tasks, including cutting, sawing, and slicing.

How are tear notches blades manufactured?

  • Cutting:
    Notched blades are produced using CNC machines to cut the desired shape from a metal sheet. The manufacturing process involves using these machines to shape the blade to the desired specifications.

  • Heating:
    After the notched blade has been cut from the metal sheet using CNC machines, it undergoes a series of heat treatment processes to strengthen and harden the metal. These processes, which may include heating, cooling, and tempering, help to give the blade the durability and strength it needs to withstand use.

  • Sharpening:
    Next, the notched blade is sharpened to remove imperfections and improve its cutting ability using CNC machining. An extra grinding process is used to refine the blade's edge.

  • Coating:
    The tips of the blades can be coated to improve the resistance to wear and corrosion using chromium and tungsten. The coating process helps to protect the blade and extend its lifespan, making it more durable and reliable.
