Multiple cavity tooling is an excellent solution for the right project. Here are some of the advantages.
Positives of Using Multi Cavity Tooling
More parts per cycle, so suitable for larger orders
Lower cost per piece that a single cavity tool
Better color consistency between parts
There are, as always, some compromises that product developers should be aware of when planning your projects.
Drawbacks of Using Multi Cavity Tooling
It takes considerably longer to design and make multi cavity tooling, and they’re more expensive
MoldFlow analysis must be performed to predict, and control, the additional stresses and limitations that the resin encounters inside the tool.
They use more complex gate and runner systems, as well as cooling channels.
It may require that the part be reoriented inside the tool to allow for different gate locations. That, in turn, will affect ejector pin marks, gate witnesses, and other minor blemishes on the finished part.
