At present, some small and medium-sized factories producing PVC profiles are still using the manual batching method. Since the batching process is a very important part of the production of PVC profiles, and the accuracy of the batching is directly related to the normal production and the quality of the products, each factory has developed the corresponding operation process and quality control measures according to its actual situation. In this article, we will briefly discuss the issues that should be paid attention to when using PVC profile production lines for the manual batching processes.
