Product Overview
As a leading manufacturer from Dongguan HonHo Jewelry Co., Ltd., we specialize in producing high-precision stainless steel rings for watch case making. Our 316L Stainless Steel Ring for Watch Case Making CNC Machined 0.5mm Precision is engineered using state-of-the-art CNC technology to deliver consistent, tight tolerances that meet the demanding requirements of luxury and mid-range watch assembly. With over a decade of experience (established in 2010) and a factory spanning 3,000–5,000 square meters, we combine craftsmanship with modern manufacturing to ensure every ring meets strict quality standards. Our ISO9001-certified production process guarantees reliability and traceability, making us a trusted partner for watch brands worldwide.
Key Features & Technical Specifications
- Material Excellence: Made from genuine 316L stainless steel – a low-carbon, non-magnetic alloy widely used in medical and marine applications due to its superior corrosion resistance, strength, and biocompatibility. Ideal for direct skin contact without causing allergies.
- Uncompromising Precision: CNC machined to a tolerance of ±0.05mm, ensuring perfect fitment with watch case components such as bezels, crowns, and casebacks. Consistent dimensions across production batches reduce assembly errors and rework.
- Surface Finish Options: Choose from polished (mirror), brushed (satin), or custom finishes (e.g., matte, bead blasted) to match your design requirements. Our finishing processes achieve uniform texture and high aesthetic quality.
- Custom Geometry: Rings can be manufactured in various outer diameters (OD), inner diameters (ID), thicknesses (height), and step profiles. We accommodate custom blueprints and 3D drawings with short lead times.
- Excellent Durability: 316L steel resists tarnishing, scratching, and daily wear, preserving the watch case's appearance over years of use. Suitable for both regular and water-resistant cases.
- Batch Consistency: Our CNC machines are regularly calibrated, and each production lot undergoes dimensional and visual inspection to ensure uniformity – critical for high-volume manufacturing.
