DfM Analysis for Thermoformed Plastic Parts

Simply upload your CAD data (e.g., STEP files) to the DfM Tool. First, the 3D data is automatically checked to ensure it is suitable and processable for analysis; you then define the relevant DfM parameters before the actual manufacturability check is performed.

The tool first checks whether the CAD model is properly created, i.e. whether it has a uniform wall thickness distribution and is correctly thickened, so that it is suitable for Design for Manufacturing analysis. Any areas that do not meet these criteria are highlighted.

The DfM-tool analyzes whether punch or milling edges are detected in the CAD model, as this is essential for further analysis. You can also define the tool side. The DfM check is then performed based on this, and both sides can be analyzed and compared sequentially.

Here, you define the desired wall thicknesses for the deep-drawn part. You can either specify a starting thickness or a minimum wall thickness—in which case the tool automatically calculates the required starting thickness as well as the resulting minimum, maximum, and average wall thicknesses.

This is where the DfM analysis begins: The demolding of the deep-drawn part after the deep-drawing process is checked, and critical areas without sufficient draft are highlighted. This allows you to immediately identify where adjustments are needed to ensure smooth removal from the mold.

This module calculates the local stretch ratio and illustrates the extent to which the material is stretched at different points on the part. The DfM analysis enables a realistic assessment of the resulting wall thickness distribution after the deep-drawing process, allowing for an evaluation of the part’s quality and functionality.

Delicate areas with insufficient wall thickness are displayed in red, while fine cavities that cannot be captured by the material appear in blue. This allows you to identify problematic geometries at a glance that could cause difficulties in tooling or mass production.
