YAFEI’s Metal Cutting Circular Slitting Blades are precision tools for the metal processing industry, designed to slit metal materials (like coils or sheets) into narrow, uniform strips. Metal slitting requires exceptional accuracy—even small deviations can ruin subsequent manufacturing steps—and YAFEI delivers this with tight tolerances, high-quality materials, and decades of metallurgical expertise. These blades are built to handle the demands of high-speed slitting lines, resist wear from hard metals, and fit leading metal processing equipment, making them a top choice for automotive, aerospace, and construction industries.
Each blade is made with tight dimensional tolerances and a sharp, consistent edge. This ensures that metal strips are cut to exact widths, with no burrs or uneven edges—critical for applications like electrical components or automotive parts.
Cutting hard metals (steel, stainless steel, aluminum) wears down blades quickly. YAFEI uses premium alloys with heat treatment to boost wear resistance, extending the blade’s life and reducing replacement frequency.
Modern slitting machines operate at high speeds, and vibration can ruin accuracy. YAFEI’s blades are balanced for stability, even at top speeds, ensuring consistent cuts without blade wobble.
The primary application of this lies in coil slitting facilities. In these specialized settings, substantial metal coils, which can consist of materials such as steel, aluminum, or stainless steel, undergo a slitting process. This process involves cutting the large coils into narrow strips. These resultant narrow strips play a crucial role in manufacturing a diverse range of products. For instance, they are utilized in the production of automotive body parts, which contribute to the structural integrity and aesthetic appeal of vehicles. Additionally, they are used to create electrical wires, which are essential for the transmission of electricity in various electrical systems. Moreover, these strips are employed in the making of construction fasteners, which are vital for securing different components in construction projects.
In industries such as electronics, where thin metal foils play a crucial role in components like capacitors or batteries, the blades serve a highly specialized function. These blades are designed to precisely slit the delicate foils into narrow strips. What makes this process remarkable is that during the slitting operation, the blades manage to do so without causing any tearing or stretching of the foils. As a result, the integrity of the foils is maintained, ensuring that they can perform their intended functions effectively within the electronic devices. This meticulous slitting process is essential for the seamless production of high - quality electronic components that rely on the proper characteristics and structure of these thin metal foils.
Yes. The blades are designed to cut through coatings (like paint, zinc, or chrome) without damaging the finish. The edge geometry minimizes friction, preventing coating smudging or peeling.
Replacement depends on usage and metal type—e.g., cutting stainless steel wears blades faster than aluminum. With proper maintenance, YAFEI’s blades last 30–50% longer than generic options. Replace when strips show uneven widths or burrs.
YAFEI’s blades fit most leading machines, including those from Siemens VAI and Danieli. For less common models, provide your machine’s specifications, and we’ll create a custom blade that fits.
Economy blades use low-grade materials and lack precision heat treatment—they dull quickly, produce uneven cuts, and need frequent replacement. YAFEI’s blades use premium alloys and precise manufacturing, reducing downtime and waste, and saving money long-term.
