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 resu...
A process for the injection molding of fluid filled plastic bodies, comprising the steps of: injecting a pressurized, flowable plastic melt into an interior of a mold cavity defined by walls to completely fill the mold cavity; cooling part of the plastic melt along the walls, thereby providing an interior of flowable, plastic melt; then providing at least one side cavity in communication with the mold cavity; injecting a pressurized fluid into the interior of flowable, plastic melt formed by cooling part of the plastic melt along the walls; expelling the...
