ABS core tubes

JSHKCORES is a China manufacturer specializing in ABS core tubes for film, foil and new energy material applications. Jiangsu Hongkai Plastic Technology Co., Ltd. focuses on polymer extrusion and injection moulding, operating a 5,000-square-metre factory premises. The products feature high rigidity, impact resistance, accurate dimensions and clean surface quality for stable winding operations.

Manufactured through precision extrusion technology using ABS resin with suitable additives, these winding cores provide uniform wall thickness, excellent dynamic balance and reliable performance for aluminium foil, copper foil, optical films, lithium-ion battery separators and electronic tapes. JSHKCORES offers different specifications to meet various equipment requirements and industrial applications, including processes such as master roll slitting, strip cutting and machine sleeving.

Core Advantages

1. High Toughness and Impact Resistance: ABS material provides excellent toughness and mechanical strength. The impact strength of ABS cores is 5–6 times that of PVC pipes, while internal pressure resistance can be up to 10 times greater. During high-speed operation or external impact, the tubes can absorb impact force through ductile deformation without sudden fracture.

2. Wide Temperature and Chemical Stability: ABS cores maintain stable performance within a wide temperature range from -40°C to 90°C, reducing the risk of embrittlement or softening during use. The material also provides good resistance to acids, alkalis, salts and electrolytes, making it suitable for different industrial production environments.

3. High Dimensional Accuracy: Precision extrusion technology enables accurate control of inner diameter tolerance within ±0.3 mm. Combined with uniform wall thickness and excellent dynamic balance, the tubes are suitable for high-speed winding production lines requiring consistent dimensions.

4. Clean and Dust-Free Surface: Manufactured through one-piece extrusion moulding, the tube walls are smooth and free from burrs, helping prevent particle shedding during operation. The clean surface performance supports applications requiring Class 10,000 and Class 100,000 cleanroom standards.

5. Reusable and Functional Modification: ABS cores can be reused more than 30 times under normal operating conditions, improving material utilization during repeated production cycles. Conductive masterbatch can also be added to produce anti-static cores for electrostatic-sensitive applications such as electronic protective films and lithium-ion batteries.

Material Features

● High Rigidity: ABS material provides strong mechanical support, helping the core tube maintain structural stability during winding processes.

● Excellent Toughness: The material offers good impact resistance, reducing the risk of damage during production, handling and repeated use.

● Lightweight Structure: ABS combines strength with lightweight properties, making it suitable for efficient roll material support.

● Dimensional Stability: Stable material performance helps maintain accurate dimensions and reliable operation in industrial applications.

● Clean Surface Performance: ABS provides a smooth surface suitable for applications requiring clean and dust-controlled winding conditions.

Specifications

The selection of specifications mainly depends on the shaft diameter of the winding equipment and the diameter and weight of the roll. 3-inch and 6-inch core tubes are commonly used specifications in the film industry.

Applications

ABS core tubes are widely used in industries that require stable roll support, accurate dimensions and clean winding conditions. Their mechanical strength and surface performance help maintain the quality and stability of roll materials during production and handling.

● Aluminium Foil Production: Provides stable support for aluminium foil rolls during winding, storage and transportation processes.

● Copper Foil Processing: Supports continuous winding operations where dimensional accuracy and structural stability are required.

● Optical Film Manufacturing: Suitable for applications requiring clean surfaces and precise roll handling.

● Lithium-ion Battery Separator Production: Provides reliable winding support for materials used in new energy applications.

● Electronic Tape Applications: Helps maintain stable roll structures for electronic material processing.
