The pressure forming workflow
Here, we present an example Multiplier workflow, from idea to final part. It is important to note that each project is unique and may require different or additional steps.
Step 1: Designing the tool
In order to give the formed plastic sheet its desired shape, you will need to use a tool. Here are some things to consider when designing your tool:
- Draft angles are essential as they make demolding much more comfortable. The greater the draft, the easier it is to remove the formed sheet from the tool.

- Undercuts should be avoided as you won't be able to remove the object once the plastic sheet cools down. However, small undercuts and vertical walls are possible when using our flexible EVA sheets.

- Air holes should be added to non-porous tools. This allows the sheet material to pick up more detail and form inside of internal voids without trapping any air.
