On September 20, 2020, a truck loaded with machine tool castings slowly departed from a cast iron mold production base, heading for a heavy industry enterprise in the Xi'an area. These machine tool castings were custom-made by the enterprise according to the specific needs of the Xi'an customer to meet the customer's requirement for production line upgrading. To ensure the products were delivered on time, the enterprise optimized the production process, allocated resources reasonably, and worked overtime to fulfill the order. After several days of long-distance transportation, the machine tool castings were successfully delivered to the customer's factory on September 25, and the customer highly praised the product quality and delivery efficiency. This shipment not only strengthened the cooperative relationship between the enterprise and the customer in the Xi'an area but also provided strong support for the development of the local heavy industry.
