Focusing on the field of new energy materials, Jiangsu Hongkai Plastic Technology Co., Ltd. meticulously crafts the ID 3 inches OD 10 inches Double-layer ABS spool. Its 3-inch precise inner diameter meets high-speed winding demands, while the 10-inch reinforced outer diameter supports high-capacity design. Combined with a 0.5μm ultra-smooth surface and glass fiber reinforcement technology, it achieves ±0.1mm dimensional accuracy, 5-year long-term stability, and 120℃ temperature resistance.

As an innovation leader in new energy materials, Jiangsu Hongkai Plastic Technology Co., Ltd. has dedicated over a decade to the R&D and production of ID 6 inches OD 10 inches Double-layer ABS reels. Leveraging its proprietary vacuum sizing extrusion technology and a 12-step precision quality control system, the company has successfully developed industry-leading ABS core shafts featuring a 6-inch inner diameter and 10-inch outer diameter.

Hongkai Plastic has dedicated many years to the R&D and manufacturing of ID 3 inches OD 8 inches Double-layer ABS spool. Utilizing glass fiber reinforced ABS modified materials as its core, the company employs low shrinkage (≤0.3%) and high-heat resistance (stable at 120°C) formulations to achieve industry-leading precision: roundness ≤0.05mm and straightness ≤0.1mm. This effectively resolves wave-like winding and sagging issues in separators, boosting customer battery yield rates by 5%+. We hold ISO 9001 quality management system certification and SGS environmental testing reports. Our products pass extreme environment validation from -40°C to 120°C with a lifespan exceeding 5 years, significantly reducing customers' overall costs.
