Mould Flow Analysis simulates how a particular plastic material will flow in a mould and enable the user to identify where injection moulding defects are likely to occur. This way, moulding issues can be eliminated before toolmakers have started to cut steel.

The software enables mould designers to understand how the mould will fill and advise on the optimal position of gates to anticipate areas difficult to fill and where weld lines will appear. The simulation can also help estimate cycle times and machine tonnage providing valuable part costing information.

Running a mould flow analysis is expensive, but it saves companies a lot of money by reducing time and costs further down the project.
