- 8 way to plating quality inspection processes
1. Salt spray test
To verify its excellent corrosion resistance, the jewelry must be continuously sprayed in a neutral (pH 6.5-7.2) salt solution for 24 hours.
2. Friction test
Apply a certain pressure to the sample to perform friction test. Only jewelry with intact coating can pass the test.
3. Artificial sweat test
Soak the jewelry in artificial sweat at 40°C, pH 5.5, for several hours and check for discoloration and corrosion.
4. Sulfur dioxide test
Apply sulfur dioxide to the sample surface and observe the number of points where the paste changes color after a period of time to evaluate the porosity.
5. Vibration wear test
Helps determine the degree of wear and tear each piece of jewelry can withstand, performing friction tests to simulate the wear and tear of long-term wear
6. UV testing
UV aging test: 24 hours of accelerated UV exposure to test surface anti-yellowing, anti-fading and durability
7. Thermal shock testing
Heat the jewelry in a high-temperature furnace for 15-30 minutes and observe whether the coating bubbles or peels off.
8. Hardness test
This test uses a 1H to 5H pencil and applies 1 kg of pressure to test the hardness of jewelry coatings.
- Finished product inspection
1. External coating inspection
We check the consistency of the electroplating process to ensure it adheres perfectly to the substrate, has a uniform color, and meets the required thickness.
2. Overall shape
Check whether the overall shape of the jewelry is consistent with the design or sample, and whether there is any deformation
3. Performance Check
Compare your finished jewelry piece to your design files to ensure every part is the way you wanted it
4. Appearance inspection
Whether the polishing is bright and uniform, without pitting, sand holes, scratches, file marks and other defects
5. Metal edges
Check whether the finished product has clear and smooth lines, no burrs or scratches
6. Structural connections
Are the welding points firm, smooth and without marks? Is the chain flexible and knot-free? Is the buckle open smoothly and safely?
7. Stone setting inspection
Check that all gemstones are firmly set, the micro-set stones are neatly positioned, the channel setting is flat, and there are no edge seams.
8. Dimensions and weight
Verify that the final product meets the required size, color and shape and achieve consistent results

Do you offer discounts for bulk orders?
Yes, we offer discounts for bulk orders. Please contact us with the details of your order to receive a quote.
Why is wholesale jewelry cheaper?
Wholesalers usually offer diamonds at much lower prices than what you would pay at a branded jewelry store because overheads like distribution and marketing costs are already eliminated. This means that you are buying diamonds from the same place, at the same price, as the fancy diamond jewelry retailers do.
Can I get a sample before placing a large order?
Yes, we offer customization and personalization services. Please contact us with your specific requirements.
What is your minimum order quantity?
Whether you are a small business or an established brand, we offer flexible solutions to meet your needs.
