Flow Simulation and Analysis

AST Technology offers Flow Simulation and Analysis services, featuring both Sigmasoft and Moldflow capabilities, to suit all customer requirements. By “test driving” the mould design via simulation, AST Engineers can reduce costs in time and materials and increase mould building efficiency, ultimately speeding time to market.


A typical analysis would include filling, packing and warpage studies to determine the part quality. AST provides all of this. But our process goes beyond the run-of-the-mill analysis:

  • A full simulation of the mould including cooling channels and the effects of mould materials can be run and analysed.

  • We complete a gate size calculation to ensure the best results from first trials of the mould.

  • We provide an estimate of the cycle time that can be achieved and machine specifications.

Unlike other flow simulation providers, AST’s engineering team takes a practical approach in providing feedback on the results of an analysis. A fully documented report is provided which includes recommendations on part improvements, gating and tooling considerations.

Part Design Optimisation:

As an additional option, AST also offers part design analysis, or Design for Manufacture, to identify potential improvements in part quality and the best tooling solution for achieving a cost-effective result. DFM includes a review of wall thickness distribution, drafting, splitting and potential gating locations.

DFM is available from AST as a separate service, but customers who combine DFM with Flow Simulation and Analysis have gained these notable benefits:

AST’s Flow Simulation and Analysis examines everything that can affect production outcomes to ensure optimised results.

AST’s DFM services combined with flow analysis provides a 360 degree view of the end-to-end manufacturing process.
