sheenstar has a research and development team with rich research and development experience, and we can customize production equipment according to customer needs. Our equipment can not only seal bottle caps with diameters of 28-30, but also small diameter bottle caps with diameters of 22-26. The production line we just shipped in our workshop uses small bottle caps for sealing. After production was completed, we conducted a trial run on the equipment and the sealing condition was well.
