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  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.
