摘要： A device including, and a method for producing, an electric insulator made of plastic, the insulator having a centrally arranged core made of glass fiber reinforced plastic, and having a plurality of insulation screens arranged coaxially around the core in an offset manner in an axial direction of the core. The method steps include: positioning a casting mold in an axial position around a vertically arranged core; producing a sealing connection between the core and the casting mold; injecting a liquid plastic material under pressure into an axial area of the casting mold; curing the liquid plastic material in the casting mold, thereby creating an insulation screen; deactivating the sealing connection; displacing the casting mold axially in a downward direction along a defined displacement path; and repeating the above steps until an insulator is produced having a desired number of insulation screens.
