摘要： A molding apparatus includes a movable molding surface with molding cavities, a pressure shoe with a stationary outer surface that defines in cooperation with the molding surface a pressure zone, and a resin source configured to introduce molten resin into the pressure zone to be forced into the molding cavities by pressure in the pressure zone. The molding surface is movable with respect to the pressure shoe to introduce molding cavities to the pressure zone to be filled with resin while the outer surface of the pressure shoe and the molding surface define in between an entrance gap of decreasing width upstream of the pressure zone. The outer surface of the pressure shoe is spaced from the molding surface in the pressure zone to define a minimum gap at which the outer surface of the pressure shoe has a slope parallel to the molding surface. The pressure shoe is adapted to be held in a flexed condition against resin in the pressure zone while forcing resin into the cavities, with the outer surface of the pressure shoe curved upstream of the pressure zone.

摘要： A method for producing an object made of a polymeric material, said polymeric material having a melting temperature (TF), comprises the steps of: melting the polymeric material; after the step of melting, cooling the polymeric material below the melting temperature (TF) in a cooling zone; severing a dose from a flow of polymeric material coming from the cooling zone by means of a severing element (5); obtaining said object by shaping the dose between a male forming element and a female forming element (10) which move towards one another with a mutual movement speed, the dose having a temperature lower than said melting temperature (TF). Between a start-of-forming configuration, in which the dose is in contact with both the male forming element and the female forming element (10), and a start-of-deceleration configuration, in which the male forming element and the female forming element (10) begin to decelerate relative to one another, the mutual movement speed is greater than 10 mm/s.

摘要： A method comprises the following steps:
providing a pre-processed element made of at least one polymeric material,
introducing the pre-processed element in a female mould part having a forming cavity,
shaping the pre-processed element between the female mould part and a male mould part, the female mould part and the male mould part being movable relative to one another along a moulding direction so as to form a concave object from the pre-processed element.
The forming cavity has a transversal dimension measured transversely relative to the moulding direction, the forming cavity further having a transition zone in which the transversal dimension passes from a larger value to a smaller value, the forming cavity further having a bottom.
During the introducing step, the pre-processed element is placed on the transition zone, so that the pre-processed element rests on the transition zone at a distance from the bottom of the forming cavity.-

摘要： 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.
