Main Features
Premium Alloy Steels: High-quality raw materials like D2 and H13 ensure high wear resistance and impact strength, essential for D2 material shear blade replacement.
Four-Edge Design: Most bottom blades are manufactured with four usable cutting edges, maximizing the utility and lifespan of the four edge square shear blades.
Critical Straightness: Advanced grinding machinery ensures extreme flatness and straightness, minimizing the cutting gap for clean, precise cuts across the entire blade length.
Compatibility: Our blades are manufactured to OEM specifications, suitable for major shear machine brands like Amada, Bystronic, Trumpf, LVD, and local Chinese brands.
Custom Slotting: Expertly machined mounting holes and slots to ensure secure, rapid installation without alignment issues.
Advantages
Extended Sharpening Cycles: Superior material and thermal treatment dramatically increase the time between regrinds.
Reduced Burr & Distortion: Tight manufacturing tolerances ensure the optimal cutting angle and minimal clearance, resulting in a cleaner shear and reduced material waste.
High Load Capacity: The toughness of the steel (e.g., high-grade H13 shear knives) allows the blade to handle thick and high-strength materials without chipping or cracking.
Custom Solutions: Specializing in complex custom shear machine tooling and non-standard sizes for specialized industrial applications.
Product Specifications
Guillotine Shear Blades: For fixed-angle and variable-rake hydraulic/mechanical shearing machines.
Crocodile Shear Blades: Heavy-duty, often curved or multi-piece blades for metal scrap alligator shear blades.
Materials: Tailored alloy selection (e.g., 9CrSi for light shearing, D2 for general use, H13 for high-temp/high-stress applications).
Length/Width: Manufactured to exact customer drawings, including precision alignment pins/slots.
