Siemens NX Tutorial: How to Extract Core & Cavity Without Mold Wizard

Learn the manual, fully parametric method for Core & Cavity extraction in Siemens NX—complete control, no Mold Wizard required. Video Overview: Are you overly reliant on the "Mold Wizard" tool in Siemens NX? While automated tools are great, they often fail on complex geometries or give you results you can't easily edit. In this tutorial, I take you back to first principles. I will show you how to manually extract the Core and Cavity using a fully parametric process. This is a critical skill for any serious Die Casting or Mold Designer. By understanding how to build your parting surfaces and define mold direction manually, you gain total control over your design, making it easier to troubleshoot errors and handle complex die changes later on. In this video, you will learn: How to assess your model for manual extraction. Creating robust Parting Surfaces without automation. Defining the correct Mold Direction manually. Parametric sketching for Core and Cavity blocks. ⏱️ Timestamps: [Note: Please adjust the MM:SS to match your video exactly before publishing] 00:00 - Introduction: Why manual extraction is a vital skill 01:20 - Defining the Mold Direction & Parting Line 03:45 - Creating the Parting Surface manually 06:10 - Sketching and Extruding the Core Block 08:30 - Sketching and Extruding the Cavity Block 10:15 - Final Boolean Operations (Subtract) 12:00 - Verifying the Parametric links 🔗 Recommended Resources: Subscribe for more High-Pressure Die Casting (HPDC) tutorials ❓ Question of the Day: Do you trust the "Mold Wizard" for 100% of your designs, or do you prefer the control of manual modeling?
