MANUFACTURING METHOD OF CAR BACK SEAT

摘要

The present invention relates to a manufacturing method of a back seat of a vehicle and a manufacturing mold used for the same. Disclosed is a manufacturing method of a back seat of a vehicle, which comprises: a coupling step for forming a manufacturing mold by coupling a mold component divided into multiple parts in a preset form; a lamination step for laminating a composite material on the outer side of the manufacturing mold coupled in the coupling step; a process step for molding a back seat unit by applying high temperatures and high pressures to the manufacturing mold laminated with the composite material inside an extra vacuum chamber and hardening the composite material; and a separation step for removing the manufacturing mold in the back seat unit gone through the process step.
