SOLIDWORKS Plastics simulates how melted plastic flows during the injection molding process to predict manufacturing-related defects on parts and molds.

You can quickly evaluate manufacturability while you design to eliminate costly mold rework, improve part quality, and accelerate time to market. A Results Adviser provides troubleshooting steps and practical design advice to help diagnose and solve potential problems.

  • Virtually assess the manufacturability and quality of injection molded part designs and tooling.

  • Leverage easy-to-use simulation to reduce development time and costs.

  • Evaluate effectiveness of mold cooling system designs for the right technical insights at the right time.

  • Maintain associativity with SOLIDWORKS CAD data and workflows.

Which SOLIDWORKS Plastics package is right for you?

SOLIDWORKS Plastics Standard


SOLIDWORKS Plastics Standard helps you ensure parts are manufacturable early in the design process. Easy to learn and use, it is fully embedded within SOLIDWORKS CAD, so you can design for manufacturability along with form, fit, and function. With SOLIDWORKS Plastics Standard, mold designs become more efficient, good parts processing windows widened, and times to market minimized.
