Injection moulding simulation results as an input to the injection moulding process

Journal of Materials Processing Technology, 2002
Abstract In the presented research work the authors tried to develop the software which will suit all the needs of the injection moulding when optimising the part-mould-technology system. The simulation results consist of geometrical and technological data.

Numerical simulation of multilayer injection moulding

Journal of Non-Newtonian Fluid Mechanics, 1997
Abstract This paper describes the finite element simulation of multilayer injection moulding in an axisymmetric cup-shaped geometry. The residual thickness of the outer material can be investigated at any stage of the filling process. The occurrence of material breakthrough is predicted and physically feasible results are presented for different ...

Best practice for benchmarking injection moulding simulation

Plastics, Rubber and Composites, 2008
Injection moulding simulation benchmarking is the comparison of predicted and actual process and quality parameters. Best practice requires that the inputs and outputs from an injection moulding simulation agree to the actual conditions of a real life moulding machine, as closely as possible.

Finite element simulation of an injection moulding process

International Journal of Numerical Methods for Heat and Fluid Flow, 1997
Considers the filling stage of an injection moulding process for polymer melts through a transient finite element method. Presents results for a thin‐walled cup‐shaped mould problem. Adopts a generalized Newtonian formulation for inelastic non‐isothermal incompressible flow under cooling conditions.

A simulation test for wear in injection moulding machines

Wear, 2001
Glass-filled polymers are known to produce considerable wear on the barrels and screws of injection moulding machines. A few model tests simulating the tribological conditions in the injection moulding machine have been developed for finding the appropriate coatings and treatments to combat the wear.

On the Simulation of Thermoplastic Injection Moulding Process

International Polymer Processing, 1997
Abstract The relevance of enhancement of crystallisation kinetics by effect of shear flow and rheology during polymer solidification to the phenomena taking place during the injection moulding process has been shown by means of simulations performed on the basis of Lord and Williams [1, 2] model and its recent extensions [3 to 5].

On the Simulation of Thermoplastic Injection Moulding Process

International Polymer Processing, 1995
Abstract Numerical simulation of the injection moulding process of thermoplastic polymers has been performed on the basis of the Williams and Lord model and its recent extensions. The aim of the simulation was to identify material properties which play a relevant role to process modelling, including post filling stages.
