Method for producing thermally crosslinkable polymers in a planetary roller extruder
A method for producing thermally crosslinkable polymers in a planetary roller extruder is presented. The planetary roller extruder has a filling part and a compounding part made of a roller cylinder region that comprises at least two, preferably at least three coupled roller cylinders, planetary spindles of which are driven by a common central spindle. The polymers are supplied in a plasticized state. The filling part is supplied with a vacuum. The flow temperatures of the central spindle and the at least two roller cylinders under a vacuum are set such that the polymers to be degassed remain in the plasticized state. One or more liquids, such as thermal crosslinkers, crosslinking accelerators, dye solutions, or dye dispersions, are metered to the plasticized polymers downstream of the vacuum degassing, preferably in a continuous manner. Finally, the resulting mixture is directly supplied to a coating assembly.

The upper mold and the lower mold are arranged on the inner sides of the upper heat plate and the lower heat plate, respectively. The upper heat plate is fixed on one end of the support post, and the lower heat plate is arranged through the support post.
PREFORM HEATING
A method for forming a fibre article, the method comprising: locating a fibre preform between a first diaphragm and a second diaphragm, the preform comprising a heat-activatable binder; drawing a vacuum between the first and second diaphragms so as to hold the preform captive between the diaphragms; positioning a first heater plate in contact with the first diaphragm; positioning a second heater plate in contact with the second diaphragm; drawing a vacuum between the first diaphragm and the first heater plate so as to increase the contact between the first diaphragm and the first heater plate; releasing the vacuum between the first diaphragm and the first heater plate; and drawing a vacuum between the second diaphragm and the second heater plate so as to increase the contact between the second diaphragm and the second heater plate.
Method And Device For Producing A Component From A Fiber-Composite Material
A method for producing a component from a fiber-composite material includes introducing a fiber impregnated with a matrix onto the inner mold of a mold space formed between the inner mold and an outer mold, introducing a separating membrane onto the fiber impregnated with the matrix such that a cavity extending along the lateral surface of the outer mold is formed between the outer mold and the separating membrane, supplying a thermal oil to the cavity at a pressure that is greater than ambient pressure such that the thermal oil acts on the separating membrane at the pressure, heating the thermal oil to above a glass transition temperature of the matrix, and cooling the thermal to below the glass transition temperature of the matrix, wherein the pressure of the thermal oil on the separating membrane is kept substantially constant at least during the cooling to below the glass transition temperature.
Temperature control device
A temperature control device is provided that is capable of making the temperature of a metallic mold speedily reach a target temperature.
