A method for temperature control in a molding tool is described. The molding tool has a tool base body and at least one cavity. The method includes producing molded parts from a fiber-containing material where a temperature of the molding tool is controlled in operation between a standby temperature and a maximum production temperature of a production temperature range. The standby temperature is lower than a minimum production temperature. The molding tool is kept at a base state by heat input where a molding process is brought from the base state into a production temperature range by an additional heat input. The production temperature range lies between the minimum production temperature and the maximum production temperature. A molding process is started after reaching the minimum process temperature in the molding tool and the additional heat input into the molding tool is maintained only during the molding process.
A method for temperature control in a molding tool, the molding tool having a tool base body and at least one cavity, for production of molded parts from a fiber-containing material, wherein preforms with a moisture content greater than 30 wt. % are pressed in a molding process to form molded parts under pressure and temperature input, wherein a temperature of the molding tool is controlled in operation between a standby temperature and a maximum production temperature of a production temperature range, wherein the standby temperature is lower than a minimum production temperature, wherein the molding tool is kept at a base state by heat input before the molding process, wherein for the molding process the molding tool is brought from the base state, in which the molding tool has at least the standby temperature, into the production temperature range by an additional heat input, wherein the production temperature range lies between the minimum production temperature and the maximum production temperature, and wherein the molding process is started after reaching the minimum production temperature in the molding tool and the additional heat input into the molding tool is maintained only during the molding process, after which the molding tool is transferred back to the base state.
