Core Advantages

1.High Toughness and Impact Resistance: ABS material provides excellent toughness and mechanical strength. ABS core tubes can absorb external impact through ductile deformation, reducing the risk of sudden fracture during high-speed production, transportation and repeated use.
2.Wide Temperature and Chemical Stability: The core tubes maintain stable performance within a wide temperature range from -40°C to 90°C. The material provides good resistance to acids, alkalis, salts and electrolytes, making it suitable for different industrial production environments.
3.High Dimensional Accuracy: Advanced extrusion technology enables accurate control of inner diameter tolerance within ±0.3 mm. Uniform wall thickness, stable roundness and straightness help ensure smooth operation on automated winding equipment.
4.Clean and Smooth Surface: One-piece extrusion moulding creates smooth tube surfaces with reduced burrs and particle shedding. The clean surface performance supports applications requiring strict winding quality and material protection.
5.Customised Solutions: JSHKCORES provides customised core tubes according to different equipment and application requirements. Dimensions including inner diameter, wall thickness and length can be adjusted, and functional treatments such as anti-static performance can be developed.
6.Quality Control: The company operates under ISO 9001 quality management requirements. Raw materials are selected from reliable suppliers, and finished products are inspected through multiple quality control procedures to ensure stable performance. Products comply with REACH and RoHS requirements.
7.Free Sample Testing: Free samples are available to help customers conduct on-machine testing and evaluate product suitability before mass production.
