On May 11, Manager Xu of the Foreign Trade Department of Hefei Huayun tested the explosion-proof sand mill and emulsification pump ordered by American customers in the factory. Huayun always insists on providing customers with high-quality products and services. It has ordered transformers specifically for testing foreign trade orders, which can test various foreign trade products with different voltages, and truly ensure that all products are tested before shipment.

After Manager Xu sent the on-site test video and pictures to the customer, he received high praise from the American customer, and the customer expressed his desire to establish a long-term strategic cooperative relationship with Huayun.
