MOVABLE PLATE FOR VEHICLE ROOF, MANUFACTURING DEVICE FOR THIS MOVABLE PLATE AND MANUFACTURE THEREOF

摘要

PROBLEM TO BE SOLVED: To provide a movable plate capable of adapting a plate base body and a functional member to mechanical and optical requirements by selecting corresponding materials. SOLUTION: A movable plate includes a plate base body 15 made from a synthetic resin and at least one synthetic resin made functional member 16 formed by injecting a material having mechanical and/or optical properties different from the plate base body 15 in accordance to a function requirement on the plate base body 15. The movable plate is manufactured by a multi- component method in a multi-component injection molding die. In regard to a first operation process injecting a first synthetic resin component, the synthetic resin is injected into a first die cavity formed by die parts of the injection molding die. For injection of another synthetic resin component 15, a slider of the injection molding die is pulled in and/or at least one of the die parts is replaced by another die part, and thus a new die cavity 24A is formed. The other synthetic resin component 15 is injected into this die cavity 24A.
