METHOD AND DEVICE FOR PRODUCING SPRUELESS FOAMED COMPONENTS

摘要

The present invention relates to a method and to a device for producing a foamed injection-molded component which is formed by decompressing a plastic which is supplemented with a physical or chemical foaming agent. By using a slider (5), which separates the sprue from the cavity (4) and subsequently follows the expansion stroke for decompressing the liquid plastic, sprueless components having a completely intact decorative surface can be produced.
