On March 15, 2019, Abrasivestocks led a group of colleagues from the abrasives industry to Japan for an investigation. In the morning, they first visited the Nissan automobile manufacturing plant to explore Japan's factory model and advanced technology. With the translation provided by Song Yuning, head of Abrasivestocks' foreign trade department, the business investigation team gained a more in-depth understanding of Japanese engine models and assembly processes. Participants reported being deeply impressed by Nissan's automatic parking technology and its application in daily life, such as the use of automatic parking technology for slippers, remote controls, and cushions.
