Our products have been sold to more than 10 countries and regions such as Japan, Europe, the United States and Australia, and have won unanimous praise f rom customers in China and abroad.
In the future, our company will concentrate i ts technical strength to increase investment in the progressiveness, automation and intelligence of carbon f iber production equipment, with aim to improve production efficiency, expand production capacity, achieve energy- saving, environmental protection and green development, and enhance core competitiveness!

Square Tube: With an excellent strength-to-weight ratio, the square tube offers high strength, allowing it to withstand significant external forces and loads while remaining lightweight for easy handling, installation, and use in weight-sensitive applications. Additionally, it features outstanding corrosion resistance, superior fatigue resistance, and effective electromagnetic shielding, enhancing equipment processing precision and operational stability. These properties reduce the risk of failure due to fatigue damage and extend the lifespan of structures. 

Carbon Fiber Roller Size Information

 

Parameter Name Parameter Details Material Carbon fiber reinforced composite material (The specific carbon fiber content, resin type, etc. can be further specified) Diameter Range Minimum diameter: [The minimum number of millimeters you expect] mm
Maximum diameter: 1000 mm (1 meter) Length Range Minimum length: [The minimum length you expect] mm
Maximum length: 10000 mm (10 meters) Density Approximately 1.6 - 2.0 g/cm³ (Varies depending on the ratio of carbon fiber and resin) Tensile Strength Generally ≥ 3500 MPa (The specific value fluctuates due to differences in processes and raw materials) Tensile Modulus Generally ≥ 230 GPa (The specific value fluctuates due to differences in processes and raw materials) Bending Strength Generally ≥ 2000 MPa (The specific value fluctuates due to differences in processes and raw materials) Bending Modulus Generally ≥ 180 GPa (The specific value fluctuates due to differences in processes and raw materials) Surface Roughness Ra value [The value you expect] μm (Can be adjusted according to machining accuracy) Roundness Error No more than [The value you expect] mm (Set according to accuracy requirements) Straightness Error No more than [The value you expect] mm/m (Set according to accuracy requirements) Operating Temperature Range -[X]°C to +[X]°C (Needs to be determined according to the actual application environment and material characteristics) Coefficient of Friction The coefficient of friction with a specific contact material is approximately [Value] (Needs to be determined according to the actual application) Weight Calculation Estimated based on diameter, length, and density. Formula: Weight (kg) = π × (diameter/2)² × length × density ÷ 1000000 Application Scenarios Such as conveying rollers in industrial production, rollers in printing equipment, transmission rollers in high - end machinery, etc. (Fill in according to the actual use) Manufacturing Process Such as filament winding molding, pultrusion molding, etc. (Fill in according to the actual production process) Appearance Color Usually the natural color of carbon fiber (Other colors can be customized as required) Surface Treatment Such as grinding, coating (Fill in according to specific processes and requirements)
