What Are the CAD Design Software?

In the field of injection mold design, selecting the right CAD design software is critical. High-quality CAD tools not only improve design efficiency but also optimize mold structure, reduce trial runs, and lower production costs. This article provides a detailed overview of the most commonly used CAD software for injection mold design, helping you choose the best solution for your needs.

Core Requirements for CAD Design Software in Mold Design

When evaluating CAD design software, we focus on these key mold design needs:

• Complex surface modeling: For handling intricate surfaces like hair dryer housings
• Mold-specific tools: Including parting surface design, slider/lifter mechanisms
• Interference checking: Ensuring no conflicts between moving components
• Mold flow analysis integration: Predicting filling, cooling, and production issues
• Engineering drawing output: Generating drawings that meet mold factory standards
