An inspection method for an injection molding device includes: a first step of acquiring a first detection value from a sensor using a test mold having the sensor, the sensor measuring a temperature or pressure of a molten material injected from a first injection molding device into a cavity section demarcated by a fixed mold and a moving mold; a second step of injecting a molten material from a second injection molding device into the cavity section and acquiring a second detection value from the sensor; and a third step of performing an inspection using the first detection value and the second detection value.

A control method of an injection molding machine that molds a molding product including a skin layer and a core layer in a mold unit by injecting a molding material to the mold unit from a nozzle, the control method including controlling, at a starting time of an injection process, a temperature of the molding material used to form the skin layer so as to be higher than a temperature of the molding material used to form the core layer.

A molding product taking-out system includes a molding machine that includes a stationary platen including a stationary mold and a movable platen including a movable mold, a take-out machine for taking out a molding product, and a control device, in which the control device causes the take-out machine to enter between the stationary mold and the movable mold that are opened, and moves at least one of the movable platen and the take-out machine such that the molding product relatively approaches the take-out machine.

A first rotation controller that rotates a rotary table by feedback control based on a rotation amount detected by a rotation amount detection unit and a second rotation controller that rotates the rotary table by the feedback control based on a distance detected by a distance detection unit are included and rotation control by the first rotation controller is switched to that by the second rotation controller at a predetermined rotation angle.

A method of forming a flat composite charge into a contoured composite part reduces wrinkles in the part as the charge is being formed. Dies are used to form a portion of charge to the steepest contour of the part, while tension is maintained on the charge as the remaining portions of the charge are formed.

A method and apparatus for performing an injection molding cycle comprising drivably interconnecting a valve pin to an electric motor actuator and controllably operating the electric motor to drive the valve pin at one or more reduced rates of upstream or downstream travel based on either detection of the position of the pin or actuator or on a preselected length of time at which to drive the valve pin.
