Cooling Analysis - What's Best For You?

July 27th, 2021 | 12:30 PM CDT


Having a cooling analysis on your mold isn’t hard to justify when you think about how it improves your part quality, molding efficiency and cycle times. But when it comes down to it, how do I know if the type of analysis that’s being run is the right one? Which one is best?

This webinar discussed
 
  • How cooling analysis works
  • What are the different types of cooling analysis that are available?

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



Image
Image
Conventional Cooling Design
  • Can’t get close to surfaces on deep core side pockets

  • Difficult to follow blade contours


Conformal Cooling Design

  • Cooling lines conform to part surface geometry

  • Able to reach deep core areas

  • Added cooling to cold sprue

So, What's Best for YOU?


  • All Cooling Analysis = Opportunity

    • Better Parts

    • Increased Profitability

  • 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
