System and method for producing plastic products from recycled mixed plastic waste and plastic product
Disclosed are plastic products from a recycled plastic mix of unidentified, unclean and unsorted mixed plastic waste made with a system comprising thermal and mechanical processing of the recycled plastic waste using continuous extrusion foaming, two-phase cooling, continuous metering of the pulling strength and automatic adjustment of the pulling speed and extrusion speed.
FLUID FEEDING SYSTEM AND MOLDING SYSTEM
The purpose is to provide a fluid feeding system which can feed fluid so that an internal pressure fluctuation of an introduction chamber provided to a discharging device is minimized to minimize a poor discharge of the fluid, and to provide a molding system provided with the fluid feeding system. The fluid feeding system 50 includes a feed channel 60 connected to the discharging device 20, a pump 80 connected to the feed channel 60, a valve 70 for blocking a flow of the fluid that flows toward the introduction chamber 28 via the feed channel 60, and a control device 100 for determining a pressure state on the pump 80 side and carrying out an opening-and-closing control of the valve 70 based on the determination result. The control device 100 carries out the opening-and-closing control in which the valve 70 is made into an open state when the control device 100 determines that a pressure P1 on the pump 80 side reaches a pressure state exceeding a given pressure.

METHOD FOR CONTROLLING RESIN MOLDING APPARATUS, AND RESIN MOLDING APPARATUS
A method for controlling a resin molding apparatus includes causing the resin molding apparatus to execute, as a single molding cycle, a series of steps including a molding step that molds a resin portion using a molding unit and a measuring-holding step that measures a resin material using a measuring-holding unit and holds the resin material subsequent to the molding step. The method also includes controlling operation of the resin molding apparatus such that the measuring-holding unit does not measure or hold the resin material in a final one of molding cycles that are executed repeatedly a predetermined number of times.

Powdery-material feeding device
A powdery-material feeding device includes a controller configured to selectively conduct constantly keeping-control of constantly keeping rotational speed of a motor, current or voltage applied to the motor without any change as a manipulated variable for a predetermined period, or feedback-control of repetitively obtaining a difference between a discharge flow rate of the powdery material and a target value thereof at predetermined cycles and adjusting by increasing or decreasing the manipulated variable at each of the predetermined cycles in order to reduce the difference, the controller conducts the constantly keeping-control immediately after a motor starts, shifts to the feedback-control when the difference between the discharge flow rate of the powdery material and the target value thereof has an absolute value less than a threshold after the period for the constantly keeping-control elapses, and conducts constantly keeping-control without shifting to the feedback-control when the absolute value of the difference between the discharge flow rate of the powdery material and the target value thereof is more than the threshold after the period for the constantly keeping-control elapses, and the manipulated variable during the repeated constantly keeping-control is changed in accordance with the difference between the discharge flow rate of the powdery material and the target value thereof after elapse of the period for latest constantly keeping-control.
