Key Cooling Message
- The fundamentals don’t change
- How do we take advantage of them?
- There are different types of Moldflow cooling analysis
- Cooling designs shouldn’t be an afterthought
- Cooling uniformity and efficiency can be improved PROACTIVELY

Cooling Uniformity
Pitch Controls Surface Uniformity


Improving Cooling Uniformity
-
Solution 1 – Add/move water
-
Solution 2 – Higher Conductivity Inserts
-
Solution 3 – Conformal Cooling
Depth Controls Core/Cavity Differential

Conventional vs. Conformal


Conventional Cooling Design
-
Can’t get close to surfaces on deep core side pockets
-
Difficult to follow blade contours
Conformal Cooling Design
Conformal Cooling design courtesy of HTS Intl. Corp.
-
Cooling lines conform to part surface geometry
-
Able to reach deep core areas
-
Added cooling to cold sprue

Turbulent Flow Reduces Cooling Time


Three Stages of Flow - Reynolds Number

Proper Circuiting = Fewer GPM

So, What's Best for YOU?
- All Cooling Analysis = Opportunity
- Better Parts
-
Increased Profitability
- Better Parts
-
No matter what type of cooling analysis
-
Temperature Uniformity
-
Coolant Flow Efficiency
-
-
Plan ahead to have Moldflow cooling analysis done proactively
-
Have analysis done at the earliest stages of product development


Buy Software, Outsource, or Both?
-
Molders/OEMs
-
Insist on Moldflow analysis – do it yourself or use an outside source
-
Know your GPM (for each line)
-
Do the math – What does X seconds of cycle savings mean?
-
-
Part Designers
-
Avoid difficult-to-cool areas, where possible
-
Use analysis to identify those areas (Moldflow Adviser)
-
-
Moldmakers
-
Be creative and test using analysis
-
Use cooling suggestions from analysis
-
