![]() ![]() GAIM module was used next to predict whether the problem can be solved by applying this advanced molding process.įirst STU ran a Moldex3D injection molding simulation on the original part design and the results matched the reality. STU used Moldex3D IM module to simulate and find out the root cause of the defects. The objective of this project was to reduce warpage and eliminate inner voids of the part. Overall cooling temperature was decreased, which led to lower shrinkage and fewer voids.Improved cooling efficiency by nearly 40%.Verified the effectiveness of GAIM application.Identified the root cause of deformation and successfully reduced warpage.High Volume Shrinkage region (b) Solutionsīoth Moldex3D Injection Molding (IM) and Gas-assisted Injection Molding (GAIM) modules were used to compare and optimize the production process. Voids were found near the rib region (Fig.Large deformation found in the central hollow area, which is critical to the assembly process (Fig.The simulation results proved that the GAIM design can greatly minimize warpage and shorten the cycle time. STU used Moldex3D to investigate the possibility of using GAIM process to improve part warpage. To improve the part deformation, this usually requires a longer packing time. Large deformation was found at the central hollow area of the cavity, together with some inner voids near the rib regions. The part was produced with conventional injection molding process. The part is a toggle of an automotive rear-view mirror. In this case study, Moldex3D helped improve warpage with Moldex3D’s gas-assisted injection molding simulation capabilities. Now, about 5000 students study at the Faculty in various courses. Faculty is focused on education of a university type graduate for industrial production, and mechanical engineering in particular. The Faculty of Materials Science and Technology of Slovak University of Technology (STU) in Trnava was established on 1 January 1986 by decree of the Czechoslovak Government. ![]()
