Abstract

In order to achieve the object of providing an electrically insulating silicone-rubber moulding, in which no appreciable shrinkage of the moulding occurs in spite of the use of silicone rubber, and the moulding times, i.e. the residence times of the elements to be moulded in the moulds, are small, for moulding the mould is inclined through 20 DEG with respect to the vertical. Moulding is performed with a thermally crosslinkable silicone-rubber composition of predetermined viscosity at an injection moulding pressure of 30 to 100 bar. In this process, for crosslinking of the silicone rubber, the mould is heated by 50 to 180 DEG above the room temperature of the composition.
