Abstract
The invention relates to a process for the injection molding of fluid-filled plastic bodies and a device to carry out this process, wherein a pressurized, flowable plastic melt is first injected by means of at least one nozzle into a mold cavity clamped by a two-part or multi-part mold until the mold cavity is completely filled. Next, after cooling of the plastic melt on the mold cavity walls has set in, a pressurized fluid is injected in such manner into the interior of the plastic melt located in the mold cavity that the still melted center of the resulting plastic body is expelled into at least one side cavity arranged outside the mold cavity and connected thereto.
