Abstract:
A method and a machine account for changes in material properties of molten plastic material during an injection run. A change in a control signal is calculated by a controller during the injection molding run. If the change in the control signal indicates a change in material flowability, the controller alters a target injection pressure to ensure that molten plastic material completely fills and packs a mold cavity to prevent part flaws such as short shots or flashing.
Abstract:
A method and a machine that account for changes in material properties of molten platic material during an injection run. If viscosity of the molten plastic material changes during an injection run, a controller alters an injection pressure to ensure that molten plastic material fills a mold cavity within a correct amount of time to prevent part flaws such as short shots or flashing.
Abstract:
A method and a machine that account for changes in material properties of molten plastic material during an injection run. If viscosity of the molten plastic material changes during an injection run, a controller alters a step time of the injection cycle to ensure that molten plastic material completely fills and packs a mold cavity to prevent part flaws such as short shots or flashing.
