Further information Students will be able to:

Replicate the most important thermal material properties, their symbols and their SI units (thermal conductivity, density, specific heat capacity, specific enthalpy) for all material classes. Estimate basic thermal material parameters without a calculator. Prepare graphs of thermal material properties as well as specific volume, viscosity and flow curves for different classes of plastics and label them correctly. Outline and explain common methods for determining the flow characteristics of plastics. Describe the flow behavior of plastics phenomenologically. Outline and explain the basic design of plastics processing machines and major subcomponents (screw/barrel, die/tool). Sketch the basic curves of state variables (pressure, temperature, ...) in plastics processing equipment for various applications and justify the differences, as well as select measurement technology required for determination. Describe the most common processing methods extrusion, injection molding, blow molding, thermoforming and classify subtypes of them.

This course is held either in German or English in consultation with the students. At least, lecture notes or book recommendations will be provided in German and English. The examination can be taken in either German or English.
