These three autoclaves were the first time that Jinma autoclave was independently exported to Korea. Our company has done a lot of work with the Korean company in the early stage. For the first time, there are certain differences in language, technology and production mode. After continuous communication and coordination for many times, the South Korean side also arranged special personnel to study on site, and the final products left the factory. Our company also arranged after-sales service personnel to conduct on-site installation and adjustment in Korea. The product samples were highly praised by users when they came out. We also obtained relevant inspection exemption certificates with three autoclaves, which is also a manifestation of the improvement of our qualification ability and comprehensive strength.
