Abstract: A molding method of a support rod that first passing a plurality of long fibers through a resin bath for impregnating with resin, then passing the plurality of long fibers impregnated with resin through a bundling hole of a position-constrained vertical plate on a machine to preliminarily form a bundle end; providing a coating layer on the machine, one end of the coating layer obliquely passes through a guiding portion on the position-constrained vertical plate to downwardly contact the bundle end; then placing the one end of the coating layer and the bundle end into a mold cavity of a mold at the same time to form a long rod body; and then cutting the long rod body into multi-segment support rods through a cutting process.
