The Universal Pin-Ring was developed by Advanced Composites for low-angle filament winding. The Pin-Ring is a low cost alternative to time wasting, self-fabricated systems.

U.S. Patent #5,468,329
Two sizes available: Large and Small
Large: 3/8" pin diameter, 16 paired rows per 12" ring
Small: 3/16" pin diameter, 48 paired rows per 12" ring

• •Works well with standard thermosets
• •Pin Rings are injection molded polypropylene forms (other materials can be used)
• •Standard 12" straight lengths can be trimmed to desired length if needed
• •Cuts easily with scissors
• •Minimal fiber bridging
• •Longer usable part lengths / less waste
• •Rigid pins minimize fiber slippage
• •Less fiber damage / breakage
• •Designed to conform to most any surface
• •Compact storage / multiple size ranges for minimal inventory and space requirements
• •No more hand made pin-rings
