High-Strength 6-Inch Inner Diameter ABS Core

As industrial film technology advances towards thinner, stronger, and higher-performance materials, the demands placed on the core winding component—the plastic core—have reached unprecedented levels. In high-tension winding applications especially, the strength, precision, and durability of the core directly impact final product quality and production efficiency. To meet this challenge, Hongkai is proud to announce the official launch of its new product: the High-Strength 6-Inch Outer Diameter ABS Core (Model: ABS-ID-6in).

This new core is specifically engineered for demanding environments such as the winding of lithium-ion battery separators, high-performance packaging films, optical films, and automotive films, all of which require high tension. It is designed to solve common issues like deformation, crushing, or dimensional instability that traditional cores may exhibit under heavy loads, providing customers with unmatched reliability.Core Advantages and Features1. Unparalleled Strength and Crush Resistance

Our ABS-ID-6in core is manufactured from high-grade ABS raw materials and features an optimized structural design, giving it superior crush resistance. It can easily withstand the continuous pressure of heavy film rolls under high tension, effectively preventing core collapse and ensuring a stable and safe winding process.

2. Precision Manufacturing for Guaranteed Winding Quality

We understand that dimensional accuracy is critical for the flatness of film products. This core's actual inside diameter is strictly controlled at 3.000 inches and the outer diameter at 6.0 inches, with exceptionally high concentricity. This ensures the film is wound with uniform tension, fundamentally eliminating quality defects such as wrinkling, bulging, or the "telescoping" effect.

3. Customized for Industrial Applications

Beyond standard specifications, we offer comprehensive customization services. Whether it's length, color, or other special requirements, Hongkai can tailor the solution to match your specific equipment and processes. Our processing services include precision cutting and molding, ensuring every core meets your exact specifications.

4. Exceptional Durability and Eco-Friendliness

ABS material not only provides high strength but also offers excellent durability and chemical stability, making it an ideal choice for reuse. Furthermore, the product is environmentally friendly and recyclable, helping our clients achieve their sustainable production goals.Target Application AreasLi-ion Battery Separators: Provides the essential rigidity and cleanliness required for the precision winding of separators.High-Performance Packaging & Transportation: Suitable for stretch films and industrial packaging films that require high-strength support.Automotive & Electronics Industries: Offers reliable winding support for high-value products like window films, protective films, and optical-grade films.Pipeline Connections & Industrial Applications: Serves as a high-strength structural component in various industrial processes.
