Product Description
Tungsten Carbide Fixed Forming Shaft
A core industrial component manufactured from ultra-hard alloy material, specifically designed for forming, guiding, supporting, and conveying applications that demand high wear resistance, precision, and long service life.
Product Overview
This forming shaft combines the near-diamond hardness and exceptional wear resistance of tungsten carbide with the toughness and strength of a cobalt (or nickel) binder phase. Engineered for outstanding performance in harsh operating conditions, it serves as the ultimate solution for replacing traditional shafts made of high-speed steel, tool steel, or hardened steel.
Core Features & Advantages
- Extreme Wear Resistance & Long Life: Hardness exceeding 90 HRA, with wear resistance tens to hundreds of times greater than high-quality alloy steel. Significantly extends equipment maintenance intervals, reduces downtime, and lowers total cost of ownership.
- High Rigidity & Anti-Deformation: Exceptionally high elastic modulus (approx. 600 GPa) ensures minimal deformation under heavy loads or high lateral forces, guaranteeing forming or guiding accuracy.
- Excellent Corrosion Resistance: Offers good resistance to most acids, alkalis, and organic solvents, suitable for humid environments or those with chemical corrosives.
- Superior Surface Finish: Can achieve a mirror-like surface finish (Ra ≤ 0.02 μm) through precision grinding and polishing. Reduces friction and prevents material adhesion, especially suitable for processing surface-sensitive materials like films, foils, and high-end textiles.
- High-Temperature Operational Suitability: Maintains high hardness and dimensional stability at elevated temperatures, offering a broad operating temperature range.
Typical Application Fields
- Plastic Extrusion & Molding: Used as sizing mandrels, feed screw journals, guide rollers, etc.
- Paper & Textile Industry: Serves as high-precision dewatering plates, doctor blade plates, hot calender rolls, guide rollers, etc.
- Wire & Strip Processing: Used as drawing capstans, guide wheels, straightening rolls, tension rolls, etc.
- Printing & Packaging: Precision plate cylinders, coating metering rods, laminating rolls, etc.
- Food & Pharmaceutical: Smooth surfaces meeting sanitary standards, used for conveyor and forming rolls.
