Your ideal paper slitting rewinding supplier

When we followed up with customers, we found that many customers are entering this industry for the first time, so not only are they a little rusty in purchasing, but also in some aspects of machine operation.

As our CTO Jimmy said in previous videos: When he was helping a customer to debug a machine, he met an African customer. He only knew that the equipment he purchased could help him produce what he needed, but he didn’t know how to operate and what was needed. Which raw materials and so on. So we help customers buy raw materials from scratch, teach customers how to open the machine, adjust the machine and so on.

At present, due to the epidemic, we can only provide online video debugging. After the epidemic, we can also arrange for engineers to provide on-site service.

So far we have assisted many customers to successfully operate the machine and join the production.
