Plastic Melt Flow Simulation Software

What is SOLIDWORKS Plastics?

SOLIDWORKS Plastics is the injection molding flow simulation add-in for the SOLIDWORKS CAD package. It simulates the flow of the plastic melt into the mold cavity and provides results that will help part designers, mold designers, and injection molding manufacturers validate and optimize their products. SOLIDWORKS Plastics runs in the SOLIDWORKS interface, which streamlines the workflow to make any design changes on the fly.

SOLIDWORKS Plastics Product Design Process

Avoid Costly Mold Cavity Rework

SOLIDWORKS Plastics can drastically reduce the chance of costly mistakes before a Mold Cavity is manufactured. Utilizing the advanced flow simulation tools can help you design efficient products and designs without the large expense of prototype testing. Modifying after a cavity is built not only causes major costs but also extensive labor to rework mold cavities.  Let SOLIDWORKS Plastics help you test CAD models before manufacturing begins to ensure the best version of your design will go to production.

"I have successfully used the SOLIDWORKS Plastics software to optimize the design of a part having thin walls and to optimize the cooling lines placement on the injection molding tool. Part warpage was the major issue that I was trying to contain. The supplier conducted a similar analysis using the Moldflow software. I have noted a good correlation in the predicted part warpage between the SOLIDWORKS Plastic and Moldflow."
