In the course of the current trends towards Industry 4.0 (smart factory), the availability of as much process information as possible is one of the first necessary steps. Process information, machine control parameter and sensor values are generally available to a large extent, but it is often not easily possible […]

Due to the poor thermal conductivity of thermoplastics, residual stresses (tensile and compressive residual stresses) are build up in the walls of the product during cooling processes after extrusion. Deformations and distortion of the products often result from the residual stresses, whereby the presence of the residual stresses becomes visible. […]
In extrusion, the temperature distribution inside the product is a very relevant value whose knowledge can contribute to understanding a variety of effects or problems. However, measuring the internal temperature of an extruded product is difficult in most cases, because in a continuous process such as extrusion (with sometimes very […]
