The Compression Molding Process In The Clamp Type Fluorine Lined Butterfly Valve

In recent years, the expansion of market demand has led to the continuous expansion of the industry scale of Lined Butterfly Valve. We all know that there are many categories of valves, and the manufacturing process of valves in different categories varies. Therefore, it is necessary to choose the appropriate valve based on the applicable environmental conditions and various factors. The clamp type fluorine lined butterfly valve emerged with the emergence of fluoroplastics and the demand of society, so this type of valve has its own characteristics in various aspects.
Among them, compression molding is one of the ideal forming processes for the application of clamp type fluorine lined butterfly valves. It is a process of placing a certain amount of fluoroplastic (powder, granular, fibrous, flake, and debris) into a molding cavity, then closing it, heating it to a certain temperature in a heating furnace, and melting it under pressure to slowly fill the entire cavity and obtain the shape given by the cavity. As the degree of chemical reaction of fluoroplastics increases, the melt gradually loses its fluidity and becomes a solid structure that does not melt. After cooling to a certain temperature and opening the mold, it becomes a finished product, thus completing the molding process.
