Anti oxidation and anti fingerprint cases of jewelry

Guangzhou's silver jewelry and Shenzhen's gold jewelry are well known all over the world. There are thousands of manufacturers engaged in the production and processing of gold and silver jewelry in the market, and the competition is fierce. All jewelry brands are actively innovating, pursuing breakthroughs in the problems of oxidation resistance and color change that have always existed in the jewelry industry. Now, with the continuous efforts of our technical team, we have developed a process to resist the oxidation of jewelry, which has improved the corrosion resistance, improved the product quality, and can meet or exceed the industry standards, which has been unanimously recognized in the market.

In 2018, in order to improve the competitiveness of silver jewelry products, a customer from Guangzhou urgently needed to solve the problem of oxidation and blackening of silver jewelry during wearing or storage. Later, he learned about the protective film equipment from our official website and contacted us. After learning about the customer's product details and requirements, we introduced the performance characteristics and related configurations of Zhenhua's protective film equipment to the customer. The customer brought the product and came to our company. Through several process adjustments and tests, the anti-oxidation film for silver ornaments without affecting the color of silver ornaments was successfully developed. The customer was very satisfied and ordered ZBL1215 protective film equipment on site and signed a contract. Later, we paid a return visit to the customer's company and learned that at a foreign exhibition in 2019, he brought silver jewelry plated with anti-oxidation film to participate in the exhibition. The silver jewelry was soaked in diluted NaOH solution on site to show the anti-corrosion and anti-oxidation tests. After watching, the foreign buyers were very satisfied and won several large foreign orders.

After a day of proofing testing, we obtained the process parameters for K gold, rose gold and other jewelry and passed the acid-base resistance test. The customers highly recognized it. At the same time, according to the needs of the Shenzhen gold jewelry market, we added the anti fingerprint coating function to make the jewelry feel smoother and have better texture. The customer finally purchased Zhenhua's ZBL1215 anti fingerprint coating equipment and placed several orders to ZHENHUA.

In 2020, the customers who have been engaged in gold jewelry processing in Shenzhen for more than ten years found that the anti-oxidation process is quietly rising in the gold jewelry market in Shenzhen. Through the introduction of friends in the industry, they learned that Zhenhua developed the earliest equipment in jewelry anti-oxidation and the process is mature. They came to our company with friends. The customer brought a 5% concentration K2S solution used to test the anti-oxidation performance, and planned to test and verify the performance of the anti-oxidation film layer in Zhenhua company. After we learned about the characteristics of gold jewelry and the treatment of previous processes in our dialogue with customers, we immediately developed a process plan and conducted sample testing.
