Using SOLIDWORKS Plastics to show Jetting

Wednesday December 11, 2013 at 2:33pm
 
SOLIDWORKS Plastics is able to calculate and illustrate the phenomenon of ‘Jetting’ within injection moulded parts. ‘Jetting’ occurs when there is a large amount of empty space in the mould cavity at, or close to, the injection location. Jetting can result in parts that have an undesirable surface finish.

To generate results that will accurately show ‘Jetting’ as it occurs you need to use a ‘Solid Mesh’. Once meshed go in to the ‘Fill Settings’, in to the ‘Advanced’ section and choose ‘Options’. In the window that opens set the ‘Volume of Fluid (VoF) Algorithm’ option to ‘Direct’.

When looking to identify ‘Jetting’ in SOLIDWORKS Plastics a ‘Flow’ study should be carried out.  The ‘Flow Results’ once ran will show the snake like channel of plastic being formed inside of the mould indicating that Jetting is likely to occur. Play the animation of results with the iso-surface mode switched on.
