Abstract
Disclosed herein is a manufacturing method of a spring pad interposed among a spring used in an automobile suspension system and an upper sheet and a lower sheet for supporting the spring, wherein the spring pad includes an insulator getting in contact with the spring to absorb shock and forming a body of the spring pad, and is manufactured through foam injection molding of the insulator to be lightweight.
Claims4
A manufacturing method of a spring pad interposed among a spring used in an automobile suspension system and an upper sheet and a lower sheet for supporting the spring,
- wherein the spring pad includes an insulator getting in contact with the spring to absorb shock, and is manufactured through foam injection molding to be lightweight,
- wherein the spring pad includes a frame combined with the insulator to enhance rigidity of the insulator,
- wherein the spring pad manufacturing method comprises:
- (S210) preparing a first molding device for injection-molding the insulator and a second molding device for injection-molding the frame;
- (S220) doing foam injection molding of the insulator through the first molding device;
- and
- (S230) inserting the foam injection molded insulator into the second molding device in order to injection-mold the frame.
