  • Press Brake Tooling
    Packaging machine serrated blades are cutting tools installed on automatic packaging equipment, primarily used to cut or seal flexible packaging materials such as packaging film, plastic film, aluminum foil composite film, and paper. They play a key role in packaging production lines in industries such as food, pharmaceuticals, daily chemicals, and electronics, directly impacting the appearance quality and production efficiency of finished products. The packaging industry uses blades to cut or trim materials such as cardboard, plastic film, and foam. They are used in packaging machines and equipment such as slitting machines, die-cutters, and laminating machines.
  • Long Blades
    A rolling knife (also known as a rolling slitting knife, steel plate slitting knife, or circular slitting knife) is a high-strength industrial tool used in the rolling, shearing, slitting, and finishing processes of sheet metal. It is primarily installed on slitting machines, slitting shears, rolling lines, and other metalworking equipment to precisely cut coils, strip steel, stainless steel, carbon steel, copper, aluminum, and other materials into strips of the desired width.
  • Long Blades
    The long blade is an industrial cutting tool with a simple structure and a wide range of applications. It is mainly used for straight-line cutting operations in industries such as plastics, rubber, paper, fiber, leather, metal sheets, wood and food processing.
  • Long Blades
    Paper cutter blades are high-precision industrial tools designed for cutting paper, cardboard, and printed materials. They are commonly installed in various paper trimmers, slitting machines, and rewinders, ensuring neat and rapid slitting of paper products. Made of high-quality alloy steel or tungsten steel (hard alloy), these blades are sharp, wear-resistant, and produce smooth cuts. They are widely used in industries such as printing, packaging, papermaking, and office equipment.
  • Circular Blades
    Polyurethane rubber sleeves (also known as polyurethane rubber rings, polyurethane rubber wheel sleeves, and polyurethane rubber roller sleeves) are wear-resistant protective components made of a high-strength metal core covered with a polyurethane elastomer. They are commonly used in rollers, slitters, winders, conveyors, and other parts of various mechanical equipment. Their primary functions are anti-slip, cushioning, protection, wear resistance, and scratch resistance.
  • Circular Blades
    Tungsten carbide circular blades (also known as tungsten steel circular knives or carbide circular cutters) are circular cutting tools made of carbide (a composite material composed of tungsten (W) and cobalt (Co)). Their distinguishing features include a disc-shaped design, evenly distributed cutting edges, wear resistance, high-temperature resistance, and excellent cutting performance. They are widely used in processing thin materials (such as film, paper, aluminum foil, and stainless steel strip), coil slitting, plastics, rubber, electronic sheets, and composite materials.
  • Circular Blades
    The tungsten carbide rewinder bottom knife is a key tool used in slitting equipment for coiled materials such as film, paper, copper foil, and aluminum foil. Installed at the bottom of a rewinder or slitter, it works in conjunction with the upper circular knife to achieve precision slitting. Made of high-quality tungsten carbide (hard alloy), this knife offers exceptional hardness, strong wear resistance, and a clean cut, making it suitable for high-speed, high-precision continuous slitting operations.
  • Special-Shaped Blades
    Packaging machine serrated blades are cutting tools installed on automatic packaging equipment, primarily used to cut or seal flexible packaging materials such as packaging film, plastic film, aluminum foil composite film, and paper. They play a key role in packaging production lines in industries such as food, pharmaceuticals, daily chemicals, and electronics, directly impacting the appearance quality and production efficiency of finished products. The packaging industry uses blades to cut or trim materials such as cardboard, plastic film, and foam. They are used in packaging machines and equipment such as slitting machines, die-cutters, and laminating machines.
  • Special-Shaped Blades
    Pelletizer blades are known by many different names: pelletizing blades, pelletizing cutting blades, pelletizing knives, die-face cutting blades, die-face blades, hot die-face cutting blades, and pelletizer cutting blades. However, their purpose is the same: to recycle materials into pellets.
  • Special-Shaped Blades
    Mask blades are key components in mask production equipment, primarily used for cutting and shaping mask fabric, ear straps, nose bridges, and other materials. They are typically installed on mask machines, slitting machines, and edge banding machines to ensure clean, burr-free cuts, improving production efficiency and mask quality.
  • Special-Shaped Blades
    Tungsten carbide laminating machine blades are high-precision cutting tools designed specifically for laminating, slitting, and packaging machines. They are primarily used for slitting and trimming plastic films, paper-plastic composite films, metal foils, photovoltaic films, and other materials. Made from high-quality cemented carbide (tungsten carbide), the blades offer high hardness, high wear resistance, and exceptional cutting sharpness, ensuring smooth and efficient cutting performance even in high-speed production.
