Abstract:
1. A method for the automated setting-up of an injection molding machine having an injection screw, said machine for manufacturing injection molded parts, comprising the steps of: (1) estimating an initial injection stroke of said injection screw; (2) estimating an initial injection velocity of said injection screw; (3) generating a substantially uniform velocity profile from said initial injection stroke and said initial injection velocity; (4) setting initial packing pressure to a minimal value achievable by said machine; (5) manufacturing a part with said machine, inspecting said part for flashing and short shots, and reducing injection stroke in response to any flashing or increasing injection stroke in response to any short shots; and (6) manufacturing a part with said machine, inspecting said part for flashing and short shots, and reducing injection velocity in response to any flashing or increasing injection velocity in response to any short shots;
