A team from the technical department of Benda Mold visited old customers, exchanged details of the mold use process with the production line personnel on the spot, and truly understood the use of Benda mold in the client side. Personnel from both sides actively exchanged the topic of mold use, maintenance and other aspects, and exchanged their respective experiences in this field. Experience is invaluable wealth. In the process of accumulating and applying experience, we can better cope with various challenges and difficulties.
