    摘要: Systems and methods for conducting thermal analysis in materials and devices having multiple thermal control zones are provided. Modem apparatuses, such as manifolds, generally have several thermal devices that introduce or remove heat at different rates from several different regions. Previous attempts to determine a thermal profile required constant guessing and an unknown number of simulations to arrive at an acceptable result. Further, since the number of simulations required is not known from the onset of the operation, the duration is unknown, which is often unsatisfactory to manufacturing personnel. Disclosed embodiments include the use of FEA to aid in designing and/or evaluating manifold systems. In one embodiment, finite element analysis is conducted to determine the heat flux caused upon other control zone by a thermal device in a specified control zone.

    摘要: Disclosed, amongst other things, is a gate insert of an injection mold that includes a base member. The base member defines a nozzle interface for receiving, in use, a nozzle of a melt distribution system that is heated, in use, by a heater, and a gate, the gate configured to fluidly link, in use, a melt channel of the nozzle with a molding cavity. The gate insert further includes a thermal regulator associated with the base member, the thermal regulator includes a direct energy conversion device that is capable of heating and cooling, wherein the thermal regulator is controllably operable, in use, to control the temperature of the gate.
