Abstract
A method for producing a high shock-absorbing automobile bumper with a smooth outer surface. The method includes the steps of loading a preformed surface skin member into a blow mold, and then blowing a parison in the mold so that the blown parison is bonded to the surface skin member. The result is a hollow cushioning body firmly bonded to the surface skin member.
