Zusammenfassung:	A helmet and method for forming a helmet having a multi-density impact liner may include forming a puck with an interface surface and at least one side. The interface surface of the puck is placed in direct contact with a receiving surface of a cap located in an impact liner mold. Next, the interface surface of the puck is thermally fused directly to the receiving surface of the cap while contemporaneously an impact liner body is formed inside the mold. The impact liner body is fused to the at least one side of the puck, and to a majority of the receiving surface of the cap. The density of the puck may be greater than the density of the impact liner body. The puck and the impact liner body may be EPS, and the cap may be PC.
