Project Background

The positioning stop of an aluminum profile cutting machine plays a crucial role in ensuring cutting accuracy and stability. Traditionally, the end support block of the stop was made from short glass fiber reinforced nylon, which often suffered from deformation, wear, and reduced precision after long-term use due to continuous vibration and impact during operation.

To improve durability and maintain dimensional stability, the client sought a material solution that combined high strength, stiffness, and long-term reliability without increasing weight or compromising processability.

Material Advantages

PA6-LGF40 demonstrated the following key advantages:

• High Strength & Stiffness: The long glass fibers form a continuous reinforcing network, significantly enhancing mechanical performance and load-bearing capacity, ensuring structural stability under repeated mechanical stress.
• Impact & Fatigue Resistance: The material maintains its mechanical integrity even under repeated cutting vibrations, preventing cracking or deformation over time.
• Dimensional Stability: The component retains accurate geometry during long-term use, ensuring consistent positioning accuracy and reducing the need for maintenance or recalibration.
• Lightweight & Processability: Compared with metal or overly dense composites, PA6-LGF40 achieves a balance between strength and weight, while still being easy to mold and assemble.

Customer Benefits

By switching to PA6-LGF40, the customer obtained a high-performance structural component that provides superior mechanical strength, impact resistance, and dimensional stability compared to the previous short glass fiber material.

The improved toughness and long-term durability of the positioning stop ensure stable cutting accuracy, reduced deformation, and longer service life of the equipment.

Additionally, the enhanced wear resistance and reliability significantly lower maintenance frequency and overall operating costs, while maintaining lightweight performance.

Conclusion

This project demonstrates the successful replacement of a short glass fiber reinforced nylon component with PA6-LGF40 long glass fiber composite in an aluminum profile cutting machine positioning stop.

The upgrade not only improved mechanical performance and durability but also exemplifies the practical application of “plastic replacing metal” and “long fiber replacing short fiber” concepts in industrial equipment components, delivering both technical and economic advantages.
