Abstract
A thin-walled work piece of plastics material is cast in a mold by pouring or flowing the plastics material in the form of a plastisol or a flowable powder into a preheated casting mold which is locked to a casting container in a sealed manner to form a closed casting cavity. The mold and the container are then lifted or rotated through at least 180.degree.. A reduced pressure is maintained in the cavity at least prior and during the tilting. After a predetermined time the reduced pressure is removed and the mold and container are tilted back into the starting position. The mold and container are then separated again and the mold is then heated for completion of the jelling or curing whereupon the mold is cooled for removing the work piece from the mold.
