: Use Analysis > Geometry > Draft Check to ensure all vertical faces have a draft angle—typically 1° to 2° is standard, while textured surfaces may require 3° to 5° .
: Import the part you want to mold. This creates a "reference part" that stays linked to the original design.
: Use the Mold Volume Split tool to divide the workpiece into distinct volumes—typically the Core (bottom half) and Cavity (top half). Mold design Using PTC Creo Parametric (Pro Engi...
Designing a mold in (formerly Pro/ENGINEER) involves a systematic workflow that transitions a 3D part model into a multi-component manufacturing assembly. By using the dedicated Mold Design module, you can automate the creation of cores, cavities, and parting surfaces while maintaining full associativity with the original design. Core Workflow for Mold Design
: Verify that wall thickness is uniform to prevent cooling issues. Create Manufacturing Assembly : Open a new file and select Manufacturing > Mold Cavity . : Use Analysis > Geometry > Draft Check
: Before starting the mold, evaluate the part for manufacturability.
: Create the raw block of material (stock) from which the core and cavity will be split. You can use the Automatic Workpiece tool to generate a block based on the reference part's overall dimensions. Develop Parting Geometry : : Use the Mold Volume Split tool to
: Use these surfaces to define where the mold halves will separate. You can create these by extending the silhouette curves to the edges of the workpiece.
