FIRST PRIZE WINNER
Project Name: Redesign of Injection Mould Cavity based on Reverse Warpage Profile
By Miroslav Košík
One of the biggest challenges of molding thick-walled parts is dimensional accuracy. In this project, a plastic hook , an automotive component part, was warped in the first tryout. However, the warpage problem still existed after adjusting the process parameters. The MTF STU team used Moldex3D to help the tool maker explore the causes of warpage and the viable solutions. As a result, the toolmaker was able to determine the best possible solution to solve the warpage problem by optimizing the mold design based on Moldex3D’s Warp analysis results, avoiding unnecessary rework.
- To reduce and control excessive warpage
- To explore viable solutions in a short amount of time
The MTF STU team used Moldex3D to help the toolmaker explore possible solutions and determined the best solution is to modify the mold based on the Warp analysis result. Moldex3D’s predictive capabilities for warpage allowed the toolmaker to make adjustments to the mold before cutting the tool. In addition, the toolmaker was able to use Moldex3D to generate and apply the opposite warpage result to the original model to optimize the mold design.
- Met dimensional specifications
- Avoided costly tooling errors and rework
- Shortened troubleshooting process
