MMT Chat: Lessons in Simulation
This mechanical engineer has a passion for simulation because he has spent most of his career working in injection molding and truly sees the value of detecting problems early in the design phase of a project.
Mark Howards founder of 3D Shapes got his start doing plastic part design before good 3-D CAD tools were available and eventually ended up providing support for a family of CAD/CAM/CAE products that included plastics analysis software.
He started 3D Shapes in 1992 doing complex 3-D surface modeling and using CAE tools to optimize the design phase and then started doing plastics consulting. He’s been consulting ever since, and has a lot of simulation insight to share.
During this quick 10-minute conversation, Mark shares common problems he sees with clients, such as fill pattern, pressure and clamp force requirements, moving knit lines, best place to gate and non-uniform and high shrinkage, which can lead to dimensional issues, sink and even voids.
More importantly, he reviews the simulation solution to these issues. Click above for the full conversation.
Turbulent-flow plastic baffles eliminate blow-by, significantly improving cooling and cycle times.
Mold cooling is the single most important factor in terms of mold productivity. Mold cooling improvements will influence cycle time and part quality - both of which will directly impact profitability.
A lesson on shear induced melt variations ends some confusion regarding balancing runner systems for multi-cavity molds.
