Abstract: Disclosed herein is a computer-implemented method for controlling and/or monitoring at least one injection molding process in at least one injection molding machine. The method includes: a) providing a set of input parameters by at least one external processing unit; b) simulating an injection molding process based on the set of input parameters and determining at least one predicted process parameter of the simulated injection molding process; c) performing at least one injection molding process using the injection molding machine; and d) determining at least one actual process parameter of the injection molding process and comparing the actual process parameter and the predicted process parameter and adapting the simulation model based on the comparison.

Abstract: A process for producing a molded article involves providing a thin-walled, gas-permeable shell; filling the shell with a foamed pelletized material composed of a polymer; and welding the foamed pelletized material to obtain the molded article. Molded articles are obtainable or obtained by such a process, and can be used as a footwear sole, part of a footwear sole, a mattress, a seat cushion, an underlay, a grip, a protective film, a component in automobile interiors and exteriors, a gymnastics mat, a body protector, a trim element in automobile construction, a sound insulator, a vibration damper, a cushion, a bicycle saddle, a toy, a tire or part of a tire, a covering for a track and field surface, a covering for a sports hall or a pathway, a damping layer or a damping core in a sandwich element, or a packaging.

Abstract: Disclosed herein are a computer-implemented method and a design system for designing a molding process for manufacturing at least one component. The computer-implemented method includes a) retrieving three-dimensional geometrical data describing a candidate shape of a mold cavity; b) analyzing the geometrical data; c) automatically interpreting at least one analysis result generated in step b) by subjecting the analysis result to at least one target specification; and d) outputting at least one interpretation result generated in step c), the interpretation result describing at least one quality of one or both of the molding process and a part design using the candidate shape of the mold cavity.

Abstract: Described herein is a computer-implemented method for simulating a filling process of a mold cavity in an injection molding process using a plastic material, the method including: i) discretizing at least a part of the mold cavity into a plurality of cells; ii) defining a cavity injection point; iii) determining a surface normal direction perpendicular to the nearest cavity sur-face for each cell; iv) determining a cell coordinate system for each cell, defined by a first principal direction parallel to a flow direction, a third principal direction parallel to the normal direction, and a second principal direction perpendicular to the first and third principal directions; and v) determining the flow direction of a mold flow for each cell.
