Ludovic : the software dedicated to twin screw extrusion

Some Applications Examples of twin screw extrusion processes optimization

Ludovic provides a complete analysis of the twin screw configuration given by the user

Ex : Modelling of a complete BC21 twin screw extruder with converging plate die and classic screw design. Rotation speed, flow rate and temperature are given by the user.

The Results obtained with Ludovic : pressure, temperature, viscosity, shear rate...

The opposite results present the sharing out of the energy during the twin screw extrusion process and the Residence Time Distribution.

Residence time distribution and global results during a twin screw extrusion process

From a simple configuration (see 1), Ludovic determines the functionning domain of the modelled twin screw extruder. This experimental plan checks all the values of extrusion conditions to determine the best parameters set.

Ex : Using Ludovic to tune parameters in order to improve the Residence Time Distribution

Ex : Set up of new material. Which are the trends of the process (higher temperature or viscosity...)?

The Results obtained with Ludovic : display of all potential variations of each parameter (speed, pressure, flow rate...) on a configuration given by the user

The opposite results present the process variation according to 3 parameters : flow rate, screw rotation speed and Residence Time Distribution variance

Ludovic provides the 5 best configurations according to parameters chosen by the user

Ex : To obtain a wished pressure or temperature. Ludovic will change the other parameters to get the pressure or temperature values chosen by the user

Ex : To minimize the energy consumption. Ludovic will respect the power imposed by the user to detemine the best process configuration

The Results obtained with Ludovic : the 5 best configurations of the extruder to reach goals fixed by the user

How to control and regulate the process parameters during the extrusion process to not damage the PP.

It can sometimes be difficults getting an even dispersion and colour in mixed pigment type systems.
How simulation can assess differences in colour, confirm process parameters and save costs.

Theoretical approach of the problem of recycling/mixing an incompatible polymer feed.
Compare measurements of dispersion droplet size

To compare new and worn equipments : when do I change my kneading elements.

Carbon nano tubes material are an expensive product. How to optimize their use by mixing and disperse them well.

How to dispers the flame retardant product without destructing its electrical properties

The softening point of this product depends on the degree of dispersion. How to improve the mixing efficiency.
