You are not mistaken. This is Crstar own Teflon coating workshop, the only metal belt manufacturer with its own Teflon coating workshop in the world. You will surely ask other people in the same industry that Teflon coating is outsourced to a third party for processing, and its cost is still low. Why do you purchase equipment to develop and produce this? Your idea is very normal. Before 2015, we also adopted outsourcing third-party processing, but the problem encountered is that the quality is very unstable. We have replaced more than ten suppliers, which is the case. Because of the unstable coating quality, we have caused great losses and even lost customers. So in 2015, we decided to invest in special metal belts.Now we are confident to say that our Teflon coated metal belt quality is No.1 in the world.
