Description

Description

Weld lines can have negatively affect the part performance as well as the aesthetics. In this class we will discuss new developments around weld line strength prediction, and show a case study about how to improve a weld line formation after holes by using a differential of local thickness. The area around hole was split in 5 zones or thickness parameters. The maximum of change was 0.5mm. The thickness change was made in Dual domain mesh and after is generate 3D mesh. The weld line was evaluate by how many edge elements was count in “Weld Line” result.

The methodology was used consist in automatic workflow using 3 main programs: ANSA is a pre-processor and responsible for change of thickness in DD mesh and export model for Autodesk Moldflow Insight; this one, by command line, is going to do 3D mesh and set up and run a fill analysis; Isight is an optimization program that will control all process and to do a DOE for measuring a sensibility of thickness around the featur.

Renan Melhado

Renan Melhado Mazza has been in the plastics industry for more than 8 years. He graduated with a degree in material engineering, and started to work at SMARTTECH in 2008, where he did many things, including customer technical support, development of new technologies and work methodologies, consultation in structural and manufacturing projects for plastic parts injection, and internal development and application of DOE methodology. He is Professional Level Certificated Moldflow user, and he develops automation flows with Isight (parametric program) and integration between software for optimization of plastic parts. In addition, he provides training for defects in plastic parts, and teaches people how to use Moldflow simulation software. Currently he is involved in optimization projects and development of new methodologies for plastic parts using computer-aided engineering programs.
