Test Center Equipped with Ground-breaking Test Equipment
Dongguan STL has experienced continuous growth in export business for European and US railways in recent years. Aiming to practice its quality-oriented brand concept and ensuring safety, stability and reliability of its products, Dongguan STL has set up a washer fatigue test center with a total investment of RMB 800,000 yuan. Inclusive of initial investment in R&D, the expenditure exceeds RMB 1 million yuan.
As a professional manufacturer of high-performance locking washers, Dongguan STL is well aware of the importance of quality stability. The company has worked with Professor Zhou (Master of Engineering Degree in Germany) from Gui|in Ruite Testing Machinery Co., Ltd. to develop a new fatigue testing machine for spring washers. In terms of performance and software application, it is the first and leading equipment in China, which can carry out up to 400,000 times of fatigue testing for washers per day. By utilizing formulas, the equipment can automatically calculate the mechanical value after the corresponding specifications are entered in the software.
At present, the fatigue testing of STL‘s disc spring washers used in the European railway sector can exceed I.8 million times. It is understood that even today the national test center has not been equipped with such advanced equipment. The establishment of the new test center means that the technical gap between Dongguan STL and its competitors is getting wider.
The testing center is highly appraised and trusted by an international French customer, who is convinced of Dongguan STL in the presence. There is no doubt that the introduction of the fatigue testing equipment will bring tremendous changes to the business development of Dongguan STL.
