Injection molding of a molded item using a PEEK material involves a filling peak pressure of 40 to 150 MPa. In addition, the injection molding may include stretching treatment, such as in-mold stretching processing, where necessary via multipoint gates. The molded item thus obtained has much higher flexibility, elasticity, or viscosity while maintaining toughness and rigidity peculiar to PEEK compared with conventional molded items made of PEEK material, and various molded items such as fitting-type locking mechanisms, hinges, and the like requiring such properties can be obtained. |
