A method for producing a formed product using a resin composition including a plurality of raw materials, in which the content of raw materials in the resin composition is measured in real time, the method comprising the steps of: supplying each of the plurality of raw materials to an extruder; melt-kneading the plurality of raw materials in the extruder to prepare a resin composition; and irradiating the prepared resin composition with radiation and calculating the content of the raw material in the resin composition based on the results of detection of the radiation transmitted through the resin composition.

The continuity of a functional layer of a web (32, 60, 78) is assessed by forwarding the web, detecting (42, 63) the presence of the functional layer and a discontinuity and/or a thin region in the functional layer, and generating a signal in response to the discontinuity and/or thin region. The functional layer comprises a detectable component (360) in a thermoplastic composition. The detecting is carried out by a machine vision system capable of detecting the detectable component (360) in the functional layer. The detectable component (360) can be active or passive. Also included are systems for carrying out the process.

A compression moulding machine comprises: an extrusion unit configured to extrude a rod of pasty polymeric material; a cutting element, configured to portion the rod into individual charges; a rotary carousel, including a plurality of moulds, each mould being configured to receive a respective charge and to form a corresponding object from the charge; a feeder, configured to convey each charge to a respective mould at a feed position; an inspecting device, configured to capture inspection data, representing a composition of the rod or of the charges.

An apparatus, a system, and a method for improvements in fused filament fabrication (FFF). Characteristics of a filament may be measured during production of the filament and the characteristics stored in a memory for retrieval by a 3D printer. The 3D printer adjusts print settings as necessary based on the measured characteristics, thereby resulting in better print quality.

The invention relates to novel processes for determining the quality of an uncrosslinked rubber mixture by means of ultrasound and to an apparatus suitable for this purpose.

A method changes the material from a feed mixture to a subsequent mixture in a feed device of an extruder, the method comprising the steps of detecting a change request for changing the material, emptying a mixing area of a mixing device of the feed device, identifying the completion of the emptying of the mixing area, and filling the mixing area of the mixing device with the subsequent mixture after the completion of the emptying has been identified.

The present disclosure relates to a method and an extrusion line in which an additive content, in particular, a carbon black content, can be determined inline during extrusion of an extrusion product. For this purpose, an initial measurement is carried out in which a layer thickness and a refractive index of the extrusion product are determined, whereupon a continuous in-line measurement of the current additive content is carried out by a stationary radar measuring device. Thus, the layer thickness is set and the additive content is determined directly by the radar measuring device and controlled by setting the additive feed rate, in particular as a close-loop control.
