Abstract
A rubber injection press with a stationary clamping table with a mould element and with a carriage with a further mould element, which carriage is movable in a direction towards the clamping table to close a mould formed by the two mould elements, has a heater associated at least with the stationary mould element and provided in the form of a heating panel, which is arranged between it and the clamping table and in which heating elements are arranged. So as to achieve a good heat transfer from the heating elements to the heating panel with, at the same time, the breakdown frequency being reduced and there being a wide range of design possibilities regarding the arrangement of the heating elements, the latter are cast in the heating panel as heating coils. Thus it is possible also to arrange rapid clamping devices in the heating panel.
