Zhang and I got to know each other in 2014, when he was developing carton machine and purchasing cardboard from me for testing machine performance. Later I went to his factory, and Zhang showed me his machine in a very comprehensive way. I was excited about this advanced machine, which was exactly what I needed. Because my customers are all in the furniture industry, their orders are very messy, sometimes only a few different sizes of boxes for a single order, we need a long time to replace the mold and set up the machine with the die cutting mold. Therefore, I became Zhang’s first customer. The first carton box machine he produced for me is still used every day. It is very reliable. Sometimes there were some small problems, Zhang always gives me timely feedback and support, thank you very much for Zhang’s support to us these years, so that I no longer have a headache in the face of small orders.
