The capping machine is widely used in bottling production lines because of its fast speed, wide compatibility range, and low price. However, the choice of the material of the capping wheel often brings some confusion to the user. Below we will analyze the applicability of different material capping wheels for everyone
1. PU material (polyurethane)
Generally speaking, polyurethane capping wheels are more wear-resistant, and are characterized by high hardness, good strength, high elasticity, high wear resistance, tear resistance, and aging resistance. Conventional bottle caps choose polyurethane capping wheels, which will have a longer service life
2. Silicone material
Silicone has high thermal stability and excellent aging resistance. The disadvantages are low tensile strength, tear resistance, and poor wear resistance. When it comes to some mirrors or metal covers, generally in order to protect the cover from being scratched when screwing the cover, a silicone wheel is used.
The above two materials are the main materials of the capping wheel. Each material has many subdivided hardness and foam physical and chemical properties. Fengfa has accumulated a lot of experience in the process of manufacturing capping machines for more than ten years. The customer chooses a more suitable capping wheel to ensure that the cap is tightened and not scratched, but also to extend the frequency of replacing the capping wheel to a greater degree.
