In order to produce good mechanical equipment, we need not only rigorous design drawings from engineers, but also strict monitoring of the entire production process. It includes not only pipe cutting errors, control of the width of welding seams, and technical engineers' control of size and angles. Of course, the spraying process is also very important, because it is the primary factor in whether a machine is popular with customers. And whether wear occurs during the final assembly of the machine and whether the machine arm is symmetrical, which is directly related to whether the machine user can achieve the expected training goals. After decades of testing, the quality of our products has gradually been recognized by customers in North America, South America, and Europe. We will continue to work hard to provide customers with high-quality products.
