On October 13th, representatives of three purchasers organized by the Italian New Energy Transportation Association arrived in Linyi, Shandong Province. They visited Hengtong Electric Technology, a leading domestic enterprise in small enclosed electric vehicles, to inspect the manufacturing process of the products on the spot, with a focus on the four core links of stamping, welding, painting and assembly, laying a foundation for deepening cooperation.
At 9 a.m., the customer group’s first stop was the stamping workshop. Inside the workshop, six 2,000-ton high-speed presses and automated production lines operate in coordination. 0.8-millimeter steel plates are precisely formed through 12 processes, with an error controlled within 0.08 millimeters. The shell of this model needs to balance lightweight and impact resistance. The precision of your molds and the efficiency of mold changing are very crucial. Italian purchaser Paolo Rossi was recording parameters while asking questions. The technical team demonstrated the intelligent production scheduling system on the spot, reducing the response time for a single batch of orders to 2 hours, which was affirmed by the customer.
In the welding workshop, 180 six-axis robots are moving in an orderly manner, with laser welding and MIG welding alternating. It only takes 90 seconds to complete the welding of each frame. “The European market has strict requirements for vehicle body strength. What are the pull-off force data of these weld points?” ” The accompanying technical consultant pressed on. The factory quality inspection supervisor displayed the real-time monitoring screen: The average pullution force reached 12,000N, exceeding the EU EN17128 standard by 15%. Customers took photos one after another for record.
The painting workshop is filled with a faint smell of paint, but there is no traditional chemical odor. The entire process uses water-based paint and RTO waste gas treatment, reducing VOC emissions by 90%. How can color difference control be guaranteed? Italian customers pay attention to details. The robot automatically mixes the paint through 3D vision scanning, with an error of less than 1.5 microns in the thickness of the paint film per square centimeter. The glossiness of the finished car body reaches over 90°. “This texture can fully compete with high-end European models!” The customer nodded in approval.
In the final assembly workshop, AGV logistics vehicles precisely deliver components, and workers scan the “one vehicle, one code” for assembly. Paul experienced the error-proofing system: if a screw was missing, the device would immediately sound an alarm. “From parts to complete vehicles, the quality control closed loop is solid!” ” He admitted that this trip had completely changed his preconceived notion of “Chinese contract manufacturing”.
Before leaving the factory, the Italian customer clearly stated: “We plan to promote this cost-effective small electric vehicle in Italy and will start the first batch of 500 trial orders as soon as possible.” ” This inspection not only brought the precise craftsmanship of “Linyi Manufacturing” into the Apennine market, but also built a bridge for cooperation in new energy transportation between China and Italy.
