Explain the three manufacturing processes in the industry to the manufacturer of clamp type fluorine lined butterfly valves

with PTFE lined valve Widely used in daily life, many check valve The product is gradually becoming well-known to people. And with the development of technology, fluorine lined valves are now widely used, suitable for fluoroplastic magnetic pumps in various industries.

Since we have talked about the general situation of PTFE lined doors, let's talk about the clamp type Fluorine-lined Butterfly Valve Let the manufacturer talk about several of these processes. Firstly, there is the molding process. This process is made using suspended polytetrafluoroethylene resin with medium particle size. During molding, the material needs to be controlled at around 19-22 ° C to begin molding. Due to the high temperature, the material is prone to clumping, which eliminates internal stress during molding. Then the sintering process involves heating up, insulation, and cooling down before machining. Next is the transfer molding process. Its meaning refers to placing the workpiece (valve body) and lining layer material together in a high-temperature sintering furnace, heating them up to a certain temperature, and taking them out. Under the pressure of the press, the lining material is slowly transported to various parts of the lining workpiece (valve body). This molding method is called transfer molding. The latter is the isobaric forming method. As the name suggests, the equal pressure forming method refers to a forming method that achieves lining effect under the condition of equal pressure difference between the inner and outer walls of all lining parts of the workpiece. The major difference between this forming method and traditional compression molding is that it achieves the condition of equal pressure difference between the inner and outer walls of the lining part of the workpiece during the pressing process.
