One of the secrets: magical high-purity pure gold
Among all kinds of gold ornaments, the demand for thousands of gold ornaments in today's society is quite large. How can we stand out from the numerous thousands of gold jewelry? Mengjinyuan thought of the method of producing high-purity pure gold jewelry with purity as a breakthrough to win the market. According to the national standard, the purity of thousands of gold is 99.9%, and the purity of thousands of gold produced by Mengjinyuan Company has reached 99.95% and 99.98% by the national quality inspection department, which is far higher than the national standard of thousands of gold. Once put on the market, it won the first battle and won the favor of customers.
The second secret: the magical "solderless welding technology"
In 2007, with the continuous demand of social sustainable development, the company developed "Solderless Welding Technology" with years of rich experience and far-sightedness to the market, saying goodbye to the situation that it is difficult to control the purity improvement of gold jewelry because of adding solder. Many gold ornaments processed by ordinary welding process contain flux composed of gold, silver, copper and zinc. These non-gold ingredients are sold to consumers at the price of gold because they "hide" the gold ornaments. As long as there are jewelry with different connection points and solder joints, the gold content of jewelry will be different. When gold jewelry is recycled, the manufacturer needs to melt the gold separation flux with a welding torch, and the weight of the flux should be removed when calculating the recycling weight, which damages the recycling value of gold jewelry to consumers. Jewelry with connection points produced by ordinary welding process generally contains 100 g of flux in 1.7 g of gold. In terms of welding technology, the company is the first manufacturer in China to develop and use solderless production technology. It abandons the traditional method of adding solder in the welding process, and welds gold together by means of high-temperature self-melting of gold and laser spot welding, which solves the weakness that gold ornaments produced by flux technology are easy to change color, fall off, lack color and allergic to the wearer after long-term use, thus ensuring that consumers can buy products with lasting color as new, not easy to break, full color and genuine price.
The third secret: the magical advantage of environmental protection, energy saving and emission reduction to improve efficiency
Because no solder is added in the welding process, it not only reduces the use of solder, but also reduces the pollution of heavy metals in solder components caused by the use of solder. At the same time, because of its high purity, high-purity pure gold can be directly put into the processing process even without secondary purification, which reduces the use of aqua regia, formaldehyde, sodium sulfite and other resources in the secondary purification process, saving more than 200,000 yuan every year, and also reducing the pollution and harm of nitrogen oxides, sulfur oxides and volatile gases to human body and environment in the secondary purification process.
After more than ten years of continuous development, Mengjinyuan has promoted the rapid development of China's jewelry industry with its extraordinary innovation ability and led the development trend of the jewelry industry. In today's global economic integration, we make full use of different geographical advantages and years of experience in production and sales management to create thousands of gold jewelry suitable for mass consumers. Under the background of the development of the information age in the future, Mengjinyuan will adhere to the consistent professional service spirit, keep innovating and forge ahead, strive to become the world's top service provider, make steady progress in the jewelry industry and create greater glories.
