Hsinchu, Taiwan — July 13, 2026 — CoreTech System Co., Ltd. (Moldex3D) has officially announced the launch of DesignSim, a Design for Manufacturability (DFM) validation tool purpose-built for product and mold designers. Built into Siemens NX, DesignSim allows users to rapidly verify product manufacturability within their familiar CAD environment without switching interfaces, achieving a seamless “design-as-validation” experience. Compared to conventional CAE validation workflows, DesignSim improves overall validation efficiency by up to 4.75×, enabling faster design iterations and shorter development cycles.

Eliminate Complex Setup and Enable Reliable Simulation for Every Designer

Embedded directly within Siemens NX, DesignSim eliminates the need for standalone software installations. Users can execute DFM analyses via an intuitive interface in just four simple steps. Solver settings and mesh sizes are automated based on validated defaults, allowing users to obtain highly reliable results without spending valuable time tweaking parameters. Furthermore, analysis results are presented through a clear interpretation layer, helping users instantly determine whether a design meets its target criteria.

Comprehensive, Designer-Centric DFM Checks

DesignSim offers 17 robust DFM checks. While empowering users to identify potential issues early in the design phase, it also ensures that critical checks seamlessly incorporate human judgment into the decision-making process. Key features include:

• Geometry Inspection: Inspect thickness distribution, cross-sections, and internal structure to catch design issues early.
• Manufacturability Evaluation: Detect undercuts, evaluate draft angles, predict sink-mark locations, check flow-length-to-thickness ratio, and estimate cooling time.
• Filling Analysis: Perform filling simulation to evaluate flow behavior, weld line and air trap locations.
• DFM Analysis: Score molding feasibility using a rule-based DFM analysis.

DesignSim helps users confirm the status of each validation after the analysis.

Powered by the Proven Moldex3D Solver Core for Trusted Results

Instead of relying on simplified or approximate analysis models, DesignSim is built on the same-level solver technology that powers Moldex3D. It leverages decades of CoreTech System’s expertise in injection molding simulation alongside its laboratory-validated material database. DesignSim provides solid, trustworthy manufacturability guidance. By enabling every design decision to be supported by reliable analysis results, DesignSim improves product development efficiency while enhancing overall design quality.

DesignSim is now officially launched, fully supporting Siemens NX (versions 2312 to 2606), and is offered as an annual subscription through authorized channels. For more product information, please visit the following link:
