Abstract
The invention concerns thermoregulated molds and tools with a defined, fine-branched and point-focal interior heat-transferring conduit, process for their production, their use and process for the thermoregulation of molds and tools. According to the invention, these molds and tools contain on the inside a thermoregulating conduit in configuration of an arterial vessel system, through which an appropriate heat-transferring medium flows for heating or for cooling. The production of these molds and tools is conducted by means of rapid prototyping processes, particularly stereolithography.
Claims21
Thermoregulated molds or tools in which heat transfer is conducted by means of a heat transferring medium capable of being introduced into the interior of the tool or the mold, said molds and tools defining a fine-branched and point-focal heat-transferring conduit in the configuration of an arterial vessel system which is in communication with one inlet and one outlet, through which the heat transferring medium is respectively introduced and discharged.
A process for thermoregulating of molds and tools comprising the steps of:
- providing a defined, fine-branched and point-focal heat-transferring conduit in the configuration of an arterial vessel system within said mold or tool, wherein said system is in communication with one inlet and one outlet through which a heat-transferring medium can be respectively introduced and discharged;
- and causing the heat-transferring medium to flow through said heat-transferring conduit from the inlet to the outlet.
