Why Mold Motion Simulation Is Worth the Time
For complex tools, watching the mold open step by step finds the collisions a static model hides.
A static model hides sequence problems
A 3D model shows a mold closed and a mold open. It does not show the order in which things move, and almost every slide collision is a sequencing problem rather than a geometry problem.
What the simulation shows
For complex molds we run a motion simulation to prove the feasibility of the mold structure. In it the mold movements can be seen from open to close, step by step.
The tools that need it most
Anything with several side actions that share space: multi-port fittings, manifolds, lamp housings, two-shot tools where a station has to rotate. If two mechanisms want the same volume at the same instant, this is where it shows up.
When to ask for it
Before the design review closes. After steel is ordered, a sequencing fix becomes a redesign.

What a Mold DFM Study Should Contain
The ten items we put in every DFM we send, and what each one is there to prevent.
What MoldFlow Analysis Actually Catches
Filling, packing, warpage, cooling — what each stage of the analysis is looking for.
Mold Standards DME HASCO Meusburger and MISUMI
Why the standard you name in the purchase order decides how your tool is maintained for the next ten years.
Two Shot Molding Versus Overmolding
Both put two materials on one part. The difference is where the first shot sits when the second one arrives.
Mold Trials and FAI Reports
What you should receive when a tool is tried, and what to do with it.
Choosing Between a Prototype Mold and a Production Mold
A prototype tool answers a different question. Buying the wrong one wastes the whole stage.
About This Guide
Who is this guide written for?
