The published image from Changhui Wire Spool Manufacturer identifies a 220 mm snap-fit plastic spool with PS/PP material marking. Selection should confirm the outside diameter, barrel, bore, and connection method together rather than relying on appearance or one dimension.
Before assembly, inspect the flanges, barrel, and snap-fit areas for completeness and cleanliness. Equipment conditions, winding material, and operating method should be included in sample approval, with dimensional and material records retained.
An empty-spool fit check and a controlled low-speed trial can verify positioning, rotation, and joint condition before routine winding. More information is available at www.chxpgd.com.
