Patent number: 10493679Abstract: When a plurality of sets of molds, spaced a predetermined distance along a circumferential direction of a rotary platen, are attached through predetermined clamp portions to a mold attachment surface of the rotary platen supported by a movable platen included in a mold clamping device and a mold attachment surface of a fixed platen opposite this mold attachment surface, at least a mold clamping force, when the mold is attached, is previously limited to a limited mold clamping force lower than a mold clamping force at the time of molding. A mold attaching mode is set that has an interlock function of preventing the limitation from being cancelled until a condition under which all the clamp portions are turned on is satisfied. The selected mold attaching mode is performed when the molds are attached and the plurality of sets of molds are sequentially attached set by set.Type: GrantFiled: April 16, 2015Date of Patent: December 3, 2019Assignee: NISSEI PLASTIC INDUSTRIAL CO., LTD.Inventor: Keiichi Tozawa

Patent number: 10427342Abstract: An injection molding machine uses a controller to effectively control its operation. The controller may determine and/or receive information regarding the machine's maximum load capacity, and may also determine a current operational load value of the machine. The controller also may determine a number of set points used to operate the machine. The controller may cause the machine to operate at these set points, thereby resulting in the machine operating at or below the maximum load value by adjusting any number of machine parameters associated with the injection molding machine.Type: GrantFiled: August 31, 2017Date of Patent: October 1, 2019Assignee: IMFLUX INC.Inventors: Gene Michael Altonen, Brian Matthew Burns, H.
