ID 6 inches OD 10 inches Double-layer ABS Reels

Featuring an optimal 6-inch inner diameter + 10-inch outer diameter design with an optimized wall thickness of 6-8mm, this ID 6 inches OD 10 inches Double-layer ABS reels by Hongkai Plastic supplier achieves ultra-high rigidity with deformation <0.05mm under dynamic loads. It perfectly meets the demands of high-speed winding (≥2m/s) for power batteries and large-capacity winding for energy storage batteries. Utilizing a 15% glass-fiber reinforced ABS formulation and 0.5μm-grade surface polishing, the product delivers temperature resistance from -40°C to 120°C, low shrinkage rate of 0.3%, and UL94 V-0 flame retardancy. This significantly enhances battery internal resistance consistency (within ±15%) and improves capacity retention after 1000 cycles by 5%-8%. Currently, the product has obtained ROHS environmental certification and passed rigorous validation by multiple leading battery manufacturers. With cumulative shipments exceeding 5 million units, it has become a critical foundational component ensuring battery safety and longevity within the new energy industry chain.

The design of the 6-inch inner diameter, 10-inch outer diameter ABS core shaft integrates precision structural parameters with high-performance material processing: its core features a matched design with a 6-inch (approx. 152.4mm) inner diameter and a 10-inch (approx. 254mm) outer diameter.

The inner diameter serves as the winding support structure, requiring dimensional tolerances strictly controlled within ±0.1mm to ensure uniform tension during power lithium battery separator winding, preventing wrinkles or fractures. The outer diameter enhances load-bearing capacity through diameter expansion.

In energy storage battery applications, each 1-inch increase in outer diameter extends the length of a single membrane roll by approximately 15%. Combined with an optimized wall thickness of 6-8mm, finite element analysis confirms dynamic deformation remains below 0.05mm during high-speed winding at 2m/s, effectively maintaining consistent battery internal resistance.

Material-wise, the core employs 15% glass-fiber reinforced ABS with temperature resistance from -40°C to 120°C, compatible with high-temperature curing processes. Combined with a shrinkage rate below 0.3%, it achieves long-term dimensional stability over five years. The surface undergoes vacuum-calibrated extrusion and 12 quality control polishing steps to Ra ≤ 0.5μm, significantly reducing separator friction resistance and static electricity generation while preventing impurity adsorption or scratches.

For outdoor energy storage applications, 0.5% hindered amine light stabilizer (HALS) prevents yellowing after 500 hours of UV aging, maintaining color difference ΔE<2 and preserving battery aesthetics. A blend of brominated flame retardants and antimony trioxide achieves UL94 V-0 flame retardancy, meeting new energy vehicle safety standards. Production employs segmented temperature-controlled extrusion (feed section: 150-165°C, plasticizing section: 165-180°C, homogenizing section: 170-180°C) with a 3:1 compression ratio barrier screw.

Vacuum degassing maintains moisture content below 0.03% to prevent bubble defects. During mold curing, spiral groove structures, segmented heating (175-190°C), and water bath cooling (20-30°C) ensure solidification. Mold dimensions are intentionally oversized by 0.5% to compensate for ABS shrinkage characteristics. Final products undergo dual verification via laser diameter measurement (±0.02mm precision) and stress testing (10-second 50N load deformation <0.1mm), guaranteeing consistent quality.

In practical applications, this ID 6 inches OD 10 inches Double-layer ABS reels shaft significantly enhances power battery performance: Each 0.1mm improvement in inner diameter precision reduces internal resistance fluctuation by 5% in square aluminum-cased batteries, while surface finish optimization increases capacity retention by 5%-8% after 1000 cycles.

For energy storage applications, modified ABS formulations (e.g., with 5% PTFE addition) maintain over 90% strength retention after 72-hour immersion in 60°C electrolyte. Foaming processes reduce density from 1.05 g/cm³ to 0.8 g/cm³, lowering transportation costs while preserving strength. This comprehensively meets the new energy industry chain's stringent demands for precision, durability, and safety.
