Organopolysiloxane moldings are prepared from (A) compounds which have radicals having aliphatic carbon-carbon multiple bonds, (B) organopolysiloxanes having Si-bonded hydrogen atoms, and (D) a hydrosilylation catalyst, by a process involving first preparing an admixture of 100 parts by weight of (A) and (B) or (A) and (D), and then feeding, into the mixer of a plastics-processing machine, either from 0.3 to 5 parts by weight of (D), based on the catalyst formulation, into the mixture of (A) and (B), or from 0.3 to 5 parts by weight of (B) into the mixture of (A) and (D).
