Introducing our premium Bottle Neck Ring – a high-precision 304 stainless steel component designed for reliable sealing, branding, and structural reinforcement of bottle necks. Manufactured by Anping County Boli Hardware Wiremesh Products Factory, a trusted manufacturer established in 1998 with annual export values exceeding US$5 million, this product reflects decades of metalworking expertise. Each ring is formed from 2.5mm thick 304 stainless steel, offering excellent corrosion resistance and durability for demanding industrial applications. We provide free technical support to assist with integration, customization, and installation, ensuring your project benefits from our engineering knowledge. Our rings are manufactured to meet standard compliance requirements, and we back every order with a 30-day return policy for your peace of mind.
These bottle neck rings are ideal for beverage, pharmaceutical, cosmetic, and food packaging industries where consistent sealing performance and a professional appearance are essential. The 304 stainless steel material maintains its integrity under repeated use, resists rust and chemical exposure, and can be polished to a mirror finish or brushed for a matte look. Our manufacturing process ensures tight tolerances (±0.1mm) and burr-free edges, preventing damage to bottle threads or caps. Whether you need standard sizes or custom diameters, we can produce rings that fit your exact bottle neck specifications.
Key Features and Benefits:
- High-Grade 304 Stainless Steel: Excellent corrosion resistance, suitable for wet environments and repeated sterilization cycles.
- 2.5mm Thickness: Provides robust structural support without adding excessive weight, ideal for manual or automated assembly.
- Customizable Dimensions: Inner diameter, outer diameter, and height can be tailored to your bottle neck design – contact us for a quote.
- Surface Finish Options: Choose from polished (mirror-like), brushed (satin), or as-machined finish to match your branding requirements.

- Free Technical Support: Our engineering team assists with material selection, design optimization, and installation guidance.
- 30-Day Return Policy: If the product does not meet your specifications, you can return it within 30 days for a full refund or exchange.

Our manufacturing process begins with precision blanking from 304 stainless steel coil, followed by progressive stamping, edge deburring, and surface finishing. Each ring undergoes dimensional inspection using automated optical measurement systems to ensure consistency. For applications requiring branding or identification, we can laser-etch logos, part numbers, or barcodes on the ring surface. The 2.5mm thickness provides a good balance between strength and flexibility, allowing the ring to snap onto bottle necks securely without deformation.
