Molding (also known as press forming or compression molding) is a process in which a powdery, granular or fibrous plastic is placed in a mold cavity at a molding temperature, and then closed and pressurized to form and solidify. Molding can be used for both thermosets, thermoplastics and rubber materials. The molding scheme provided by the ring particles may include an insulating material molding process, a fluoroplastic molding process, and a thermoplastic molding process.
