On June 23, 2017, the company's general manager personally led the after-sales service personnel to conduct a follow-up visit on the after-sales service of the company's old customer - Hefei Tianwu Jinbai Co., Ltd. The customer purchased the company's EPS pre generator in 2012, and after more than 5 years of operation, it is still in good condition. Key components such as valves and reducers have never been replaced or repaired, and the equipment's material accuracy is still very good. The company always insists on regular free follow-up and service tracking for new and old customers, with the aim of ensuring that the equipment remains in good condition throughout the production process.
