Molding of plastic flange cover:

The choice of plastic molding mainly depends on the type of plastic used(Thermoplastic or Thermosetting)The initial form and the shape and size of the product. The commonly used methods for processing thermoplastic plastics include extrusion, injection molding, calendering, blow molding, and thermoforming. For processing thermosetting plastics, compression molding, transfer molding, and injection molding are generally used. Plastic molding is the process of shaping various forms(Powder, granule, solution, and dispersion)The process of making products or blanks of the desired shape from plastic. There are over thirty methods of molding. Its choice mainly depends on the type of plastic used(Thermoplastic or Thermosetting)The initial form and the shape and size of the product. The commonly used methods for processing thermoplastic plastics include extrusion, injection molding, calendering, blow molding, and thermoforming. For processing thermosetting plastics, compression molding, transfer molding, and injection molding are generally used. Layering, molding, and thermoforming are the processes of shaping plastic onto a flat surface.

Prevent damage during loading, unloading, and transportation. Our company produces wire protectors.Wire protection cap.Plastic steel wire protection cap.Oil drill pipe protective cap.Oil steel pipe thread protectors and other companies produce plastic pipe caps with inner caps made in a page shape. They do not have significant requirements for the wall thickness of the steel pipe and are a common and universal type of pipe cap in the world. Plastic caps have strict requirements for the outer diameter of steel pipes, so only standard steel pipes with outer diameters can be used. The main characteristics of plastic cap materials are that they have solved many problems in China's chemical, petroleum, pharmaceutical and other fields. Its main materials are: polytetrafluoroethylene seals, gaskets, and washers.The main characteristics of its material are: PTFE seals, gaskets, and sealing washers are made by molding suspended polymer PTFE resin. Compared with other plastics, polytetrafluoroethylene has the characteristic of chemical corrosion resistance and has been widely used as a sealing material and filling material.
