  • Patent number: 11926085
    Abstract: A method is provided for controlling an injection molding system, which includes a mold having an inner surface defining at least two groups of cavities, each group of cavities defining precisely one cavity with one pressure sensor at the inner surface. Each group of cavities is at least partially surrounded by a tempering unit that provides an energy flow to the surrounded cavities. According to the method, a pressure is determined in each group of cavities of the at least two groups of cavities. A reference pressure is determined for each group of cavities. A difference between the reference pressure and the pressure in at least one group of cavities is determined and controlled to become minimum by manipulating the energy flow of the tempering unit.

  • Patent number: 11241741
    Abstract: For conditioning build material for fused filament fabrication, thermal power is both added to and removed from a nozzle in a manner that can reduce sensitivity of the nozzle temperature to fluctuations in build material feed rate. The amount of thermal power added is at least as large as the sum of the amount removed, the amount to condition the material, and losses to the environment. The amount removed may be at least as large as half the thermal power required to condition the material to extrusion temperature, and may be comparable to, or much larger than the conditioning amount. The larger the ratio of the amount removed to the conditioning amount, the less sensitive the nozzle temperature will be to fluctuations in build material feed rate. Fine temperature control arises, enabling building with metal-containing multi-phase materials or other materials that have a narrow working temperature range.

  • Patent number: 9120263
    Abstract: An adaptor plate is provided between a platen and a mold to measure a temperature of each of divided regions obtained by dividing the adaptor plate into a plurality of regions and adjust a temperature for each of the regions. By doing so, it is possible to adjust the temperature at points closer to the center of the mold than tie bars. Further, by adjusting the temperature of the adaptor plate provided between the platen and the mold, it is possible to precisely adjust a tie bar balance and a platen parallelism even during molding.
