Abstract: An injection molded part is formed of a base part and a soft component which includes a cushioning shaped part fastened thereto. Injection (molding is performed without additional connection steps by having the cushioning shaped part have a soft, cast gel body completely covered on its boundary surface with a hard component that is a flexible and elastically deformable material which forms a circumferential flange-like rim protruding laterally beyond the cast gel body. During injection molding the hard component is being surrounded by the material of the base part while shielding the cast gel body from the injected material used to form the base part.

Abstract: A cushion-like shaped body (1) having an elastic, gel-like filling (2) in a thin-walled outer layer (3) are frequently used as seals, cushions, vibration dampers or shape compensation materials. This shaped body (1) is to be able to withstand severe strains, distortions, compressions and flexural forces, both in the event of brief severe stress and in the event of prolonged stress. For this purpose, the cushion-like shaped body (1) has a filling (2) of a polyurethane having Shore 000 hardness less than or equal to 80 and a compression set less than or equal to 14%, and this filling (2) is present within a shell having an outer layer (3) of a soft silicone material having a layer thickness of 0.075 to 1 mm and a Shore A hardness between 3A and 45A. Such a shaped body (1) is able to return to its original form without lasting elongation after tensile strain at room temperature up to 250%. There is no formation of cracks, detachment phenomena, bubbles, folds or other lasting damage.
