Welcome to Anping County Boli Hardware Wiremesh Products Factory – a trusted manufacturer since 1998 with annual export value of US$5–10 million. We specialize in precision-molded plastic components for the beverage packaging industry. Our Plastic Ring for Wine Bottles is engineered specifically for automated capping machines, providing a reliable, secure seal on every bottle. Whether you need standard dimensions or custom designs, our rings ensure consistent performance, reducing downtime and waste in your production line.
This product is the result of decades of experience in metal and plastic fabrication, combined with rigorous quality control. Each ring is manufactured from high-grade, food-safe plastic materials to withstand the mechanical stress of high-speed capping while maintaining a perfect seal. The ring’s design minimizes friction and wear on capping heads, extending the life of your equipment. Available in multiple colors and sizes, our plastic rings are compatible with most standard wine bottle neck finishes.
Key Features & Technical Specifications
- Precision Molded: Each ring is injection-molded with tight tolerances (±0.1 mm) to ensure uniform fit and seal.
- Material Options: Available in PP, PE, or PET – all materials are BPA-free and can be certified food-grade upon request.
- Wear Resistance: The plastic is formulated to resist cracking, deformation, and chemical attack from wine acids.
- Temperature Range: Suitable for ambient temperature filling and cold storage; optional heat-resistant variant for hot-fill processes.
- Easy Installation: Designed for snap-fit or press-fit application on capping machine chucks, with no tools required.
- Low Friction Coefficient: Reduces torque variation and prevents bottle cap skidding during capping.

Frequently Asked Questions
-
Q: What materials are these plastic rings made of?
A: They are typically made from polypropylene (PP), polyethylene (PE), or PET. All materials are food-safe and BPA-free. Food-grade certification can be provided upon request. -
Q: Can I get custom sizes for my specific bottle neck?
A: Yes, we offer full customization. Just provide your bottle neck diameter, cap type, and machine model – we will produce rings to your exact specifications. -
Q: Are these rings compatible with all automated capping machines?
A: They are designed for most standard capping machines (e.g., rotary, in-line, and pneumatic). However, we recommend sending us your machine’s chuck dimensions for a guaranteed fit. -
Q: How many rings come in one package?
A: Standard packaging is 1000 pieces per bag, 20 bags per carton (20,000 pieces total). Custom packaging is available for bulk orders. -
Q: Do you provide samples for testing?
A: Yes, we offer free samples (you pay shipping). Contact our sales team to arrange a sample set that matches your requirements. -
Q: What is the typical lead time for production?
A: For standard sizes, lead time is 7–10 days after order confirmation. Custom orders may take 15–20 days depending on complexity. -
Q: How do I ensure the ring will not slip during high-speed capping?
A: Our rings feature a slightly textured inner surface to increase grip, and the material has a low coefficient of friction to prevent slipping. We also offer a version with a small lip for extra retention. -
Q: Are these rings suitable for hot-fill wine bottling?
A: Standard rings are suitable for ambient and cold fill. For hot-fill applications (up to 85°C), we recommend our heat-resistant variant made from PET. Please specify when ordering.
