Abstract: A plasticizing unit includes an injection cylinder having a dispensing opening, via which a plasticized material can be dispensed, and a plasticizing screw arranged to be rotationally and linearly movable in the injection cylinder and having an axis of rotation. A plasticizing zone is formed between the plasticizing screw and the injection cylinder in the radial direction relative to the axis of rotation of the plasticizing screw. The plasticizing screw has a dam element, and in the injection cylinder there is a first opening in the area of the plasticizing zone and/or the dam element and a second opening between the dam element and the dispensing opening.

Abstract: A method involves heating fiber-reinforced semi-finished products of differing wall thickness to a required temperature above the glass transition range or the matrix melting temperature of a plastic matrix of the semi-finished product to be heated. In a first step, the semi-finished product to be heated is heated by thermal conduction to below the glass transition range or the matrix melting temperature. In a further step, the remaining amount of heat for reaching the required temperature above the glass transition range or the matrix melting temperature is introduced by thermal radiation or thermal convection.

Abstract: A temperature control apparatus includes a temperature control branch connected to a feed line for a temperature control medium, a pump system including a pump for conveying the medium, a pump open-loop or closed-loop control device for controlling the output of the pump system, a throttle device having a variable degree of opening for throttling a quantitative through-flow of the medium in the temperature control branch, and an open-loop or closed-loop control device with the degree of opening of the throttle device as a setting value and with a control variable from the group: degree of opening of the throttle device, temperature, temperature difference, through-flow, pressure or a physical value to be derived from that group. The pump open-loop or closed-loop control device is configured to control an operation of the pump to adjust the delivery output of the pump system depending on the degree of opening of the throttle device.

Abstract: A rotating apparatus includes a rotary plate for mounting a tool part, a rotary shaft connected to the rotary plate, a rotary feedthrough including a stator, and a rotor connected to the rotary shaft for feeding through at least two media to the rotary plate. The rotor has a first rotor part for feeding through a first medium and a second rotor part for feeding through a second medium, and the first and the second rotor parts are thermally separated from each other. A first media routing for the first medium is in the form of a hose and/or pipe for the first medium from the first rotor part past the connecting part to the rotary plate. A connecting part is non-rotatably connected to the second rotor part and the rotary shaft. The hose and/or pipe extends from the first rotor part.

Abstract: A hydraulic drive apparatus includes a first hydraulic pump, a drive motor connected to the first hydraulic pump, a hydraulic line system connecting the first hydraulic pump to the consumer, and a closed-loop control unit. The closed-loop control unit has a first switching element to change a displacement volume of the first hydraulic pump between a predetermined minimum value and a maximum value. A second hydraulic pump is connected to the drive motor, and the hydraulic line system connects the second hydraulic pump to a consumer and has a first branch line connected to the first hydraulic pump, a second branch line connected to a second hydraulic pump, and a main line. The two branch lines open into the main line, and the closed-loop control unit has a second switching element for changing a displacement volume of the second hydraulic pump between a predetermined minimum value and a maximum value.

Abstract: A method of arranging, in particular thermoplastic, semi-finished products by using an electronically controlled or regulated placing device for the semi-finished products. The method includes detecting at least one part of an outline of a semi-finished product to be placed, wherein the detecting is carried out by a detection device, determining a target position for the semi-finished product and/or for the placing device for placing the semi-finished product by matching the at least one part of the outline with a placing edge occurring on an underlying surface, and placing the semi-finished product by the placing device using the target position.

Abstract: A method for automatic monitoring of a production process includes automatically determining a value of an indirect process quantity from at least one value of a process quantity. From the determined value, a preliminary reference value is determined, and a preliminary reference value is respectively allocated to a reference quantity. It is checked whether the preliminary reference value lies within a range of reference values permitted for the associated reference quantity. If not, the preliminary reference value is transformed into the permitted range of reference values and the transformed value corresponds to a limited reference value. Otherwise, the limited reference value corresponds to the preliminary reference value. It is checked whether at least one value of a monitored process quantity of the current production process represents an anomaly with regard to the limited reference value of the reference quantity, and/or a composite reference value of one composite reference quantity.

Abstract: An injection arrangement for a moulding machine includes a moulding compound reservoir and an injection unit. The moulding compound reservoir is configured to provide a plasticized mass and to push out the plasticized mass through a discharge opening, and a connecting device is coupled to the discharge opening of the moulding compound reservoir and a feed opening of the injection unit, and is configured to direct the plasticized mass from the moulding compound reservoir to the injection unit. The connecting device includes an articulated element, and a relative movement between the moulding compound reservoir and the injection unit can be performed with the articulated element.

Abstract: An injection unit for a shaping machine includes a plasticizing cylinder which has a collar and a carrier portion which has a trough. The plasticizing cylinder is arranged in the trough, and an axial movement of the plasticizing cylinder relative to the carrier portion is restrained in positively locking engagement by the collar bearing against the carrier portion. A clamping element which is fixed or shaped on the plasticizing cylinder is fixed by fixing elements to the carrier portion in such a way that the plasticizing cylinder is braced between the trough and the clamping element. The plasticizing cylinder is braced by bracing elements against lifting of the collar off the carrier portion in an axial direction of the plasticizing cylinder.
