An Analysis of Stainless Steel Jewelry Manufacturing Processes

The production of stainless steel jewelry is actually a relatively simple yet technical process. Below is a brief overview of the manufacturing process for stainless steel jewelry:

I. Raw Material Quality Control Standards

1. Medical-grade stainless steel (316L or 304L) should be prioritized; its nickel and chromium content must comply with the ASTM F138 standard
2. The material surface must be free of scale and rolling defects, with a Rockwell hardness controlled within the range of HRB 80–95

II. Requirements for Professional Processing Equipment

1. Precision wire forming machine: Ensures a machining accuracy of ±0.1 mm
2. CNC laser drilling equipment: Holes in wholesale stainless steel jewelry must have a diameter tolerance of within 0.05 mm
3. Multi-station polishing system: Includes three processes: rough polishing, fine polishing, and mirror polishing

III. Key Quality Control Points

1. The processing environment must maintain constant temperature and humidity (22±2°C, 45±5% RH)
2. Tensile strength testing must be performed on every batch of products (≥520 MPa)
3. Surface roughness must be controlled below Ra 0.2 μm
4. All sharp edges must be chamfered (R ≥ 0.3 mm)
5. Ultrasonic Cleaning System: Uses a combination of deionized water and specialized cleaning agents.
