Abstract
A method of producing molded parts from several components in plastics processing machines is described, whereby for each component plasticized plastic material is injected into cavities formed by two mold halves, and whereby a sprue element ( ) is provided at least for the first component ( ). The sprue element of at least the first component remains on the molded part and is molded around, entirely or partially, by the next component during one of the following working cycles. This saves additional working steps for the removal of the sprue and prevents possible impurities of the environment, especially in the case of brittle material,
