Abstract:
A method for producing injection-molded parts by a two-component injection-molding technique in which a first material component is injected into a mold cavity and is displaced into peripheral regions of the mold cavity by injecting a second material component. The first material component is injected into a partial region of the mold cavity at a first gating point and the second material component is injected into the mold cavity at a second gating point and, as a result, the first material component is acted upon by the second material component and displaced in the direction of the regions of the mold to be filled with the first material component. The first material component is thereby displaced into regions of the mold at the wall, and the second material component is introduced in those regions of the mold as a core material and completely into other regions of the mold.
