Hello,
for fiber composite parts it is important to make molding tools.
CNC molding tools are expensive so I decided to make the tool at the workbench.
You need a 3D geometry and cut-curves.
For symmetric molding tools, I used wooden templates to cut with a hot wire.
Then I cut styro plates.
Following pictures and the video gives yo a overview, how to make the tool.
Kind regards
Ulrich
