ABS tube rolling cores

Jiangsu Hongkai Plastic Technology Co., Ltd. (JSHKCores) is a professional manufacturer specializing in the research, development and production of ABS tube rolling cores. With more than 10 years of experience in ABS core tube manufacturing, JSHKCores provides high-quality 3-inch and 6-inch ABS tube rolling cores widely used in lithium-ion battery separators, optical films, plastic films and other roll-to-roll processing industries.

Product Advantages

High Precision for Stable Winding Performance

Precision is critical for winding applications, especially in lithium-ion battery separator and optical film production. JSHKCores manufactures ABS tube rolling cores through advanced extrusion technology and precision calibration processes to ensure accurate dimensions and stable performance.

Key precision indicators include:

● Inner diameter tolerance control
● Wall thickness uniformity
● Excellent straightness
● High roundness accuracy

These features help ensure proper matching with winding equipment, reduce vibration during operation and maintain consistent roll quality.

High-Quality ABS Material for Reliable Performance

JSHKCores uses high-quality ABS resin as the primary raw material to manufacture ABS tube rolling cores. According to application requirements, standard ABS materials or anti-static modified ABS materials can be selected.

ABS material provides:

● Good rigidity and impact resistance
● Stable mechanical strength
● Excellent dimensional stability
● Resistance to deformation during use

These properties allow the cores to maintain reliable performance during repeated winding operations.

Smooth Surface Finish to Protect Wound Materials

The surface quality of the core directly affects the quality of the finished roll. Through controlled extrusion and surface inspection processes, JSHKCores ensures that the surface of the cores remains smooth and consistent.

The optimized surface finish helps:

● Reduce friction between the core and wound materials
● Prevent scratches or damage to sensitive films
● Improve winding uniformity
● Support high-speed production processes

This makes the products suitable for industries with strict surface quality requirements, including lithium battery separators and optical films.

Strict Manufacturing Process and Quality Control

To ensure stable product performance, JSHKCores implements strict quality control throughout the entire manufacturing process.

Raw Material Inspection

Before production, incoming ABS resin is inspected for key properties, including:

● Melt flow index
● Moisture content
● Material appearance

For moisture-sensitive ABS resin, drying treatment is performed under controlled conditions, typically at 70--85℃ for 2--6 hours, reducing moisture content below 0.1% to prevent extrusion defects such as bubbles and silver streaks.

Precision Extrusion Production

During production, dried ABS materials are accurately mixed with functional additives such as color masterbatch and anti-static agents according to product requirements.

The material then passes through a precision extrusion process, including:

1. Controlled melting and plasticization
2. Precision die extrusion
3. Vacuum calibration
4. Cooling and shaping
5. Haul-off traction
6. Cutting to required length
7. Final inspection and packaging

This manufacturing process ensures consistent dimensions and reliable quality for every batch.

Product Applications

ABS tube rolling cores are widely used in roll material processing industries, including:

● Lithium-ion battery separator winding
● Optical film production
● Plastic film manufacturing
● Adhesive tape winding
● Other precision winding applications

The products provide stable support for materials during winding, storage and transportation processes.
