The invention relates to a method for determining polymeric product properties (), wherein a prediction model () is provided for calculating polymeric product properties () based on production parameters on a computer system, which production parameters comprise formulation portions () specifying raw material portions for polymeric production and comprise processing parameters () specifying process properties during polymeric production, wherein user input is provided to the computer system, which user input comprises user production parameters () specifying a set of production parameters, user product parameters () specifying polymeric product properties and a proximity metric for quantifying conformity with the user product parameters (), wherein the computer system applies the user production parameters () to the prediction model () to calculate resultant product properties (), wherein the computer system applies the proximity metric to the resultant product properties () with respect to the user product parameters () to determine at least one proximity value indicating a match between the user product parameters () and the resultant product properties (). The invention also relates to a corresponding computer system for determining polymeric product properties.

Method and computer system for determining polymeric product properties

A method for improving the production of a cased device (), wherein a casing component () of the cased device () is produced, which production of the casing component () comprises injecting a polymer mixture () for creating a solid foam interior into a cavity, which cavity is formed by the casing component (), which injecting is done by an injection apparatus () and which injecting is based on injection control data () input to the injection apparatus (), wherein during the injection of the polymer mixture () into the cavity forming data () for describing the injection process is recorded, wherein after injecting the polymer mixture () into the cavity at least one image of the casing component () is recorded and wherein based on the forming data (), the at least one image and the injection control data () a prediction model () for generating new injection control data () for inputting to the injection apparatus () is updated.

Vacuum-supported method for the production of polyurethane foam

The invention relates to a method for producing foamed molded bodies comprising the steps of

Method for producing foamed molded bodies

A cavity between inner and outer walls of an open-box-shaped mold is filled with a polyurethane reaction mixture, containing an isocyanate and an emulsion of an isocyanate-reactive composition with three polyols and a blowing agent, which is cured to a polyurethane containing polymer. The inner and outer wall are a fixed distance from one another and each wall comprises a bottom and sides. The mixture is fed through an inlet in the bottom of the outer wall. Before filling the cavity, the mold is turned downwards so that the mixture foams upwards, filling the cavity. The three polyols are polyether polyol obtained by adding an epoxy to carbohydrates or difunctional or higher-functional alcohols; polyether polyol obtained by adding an epoxy to an aromatic amine; and polyester polyether polyol obtained by adding an epoxy to the esterification product of an aromatic dicarboxylic acid derivative and a difunctional or higher-functional alcohol.
