Company information
We have always pursued what the ideal form of a manufacturing company should be. Starting from the casting industry, we have prioritized becoming a company that delights our customers and encourages them to place orders with us. We have expanded our scope from casting to processing, and have continued to advance into mold-making, assembly, and business development in China. Our expansion into China has lasted for about 24 years, during which we have also focused on the recruitment and development of local employees. In 2006, we established "Zhengzhou Rixin Precision Engineering Co., Ltd.," a 100% wholly-owned mold and processing factory. In 2010, we founded "Zhengzhou Rixin Precision Machinery Co., Ltd.," which handles everything from manufacturing molds for aluminum die casting and aluminum gravity to the production and sales of aluminum gravity machines and shell machines. We are constantly broadening our scope of manufacturing and pursuing improvements in productivity.
