Inventor Simulation – Pushing results into single part FEA

    In my last post I took a look at working with Inventor Simulation, some basic set-ups etc… This week I am going to take it one step further taking those results and utilizing them for part FEA. The software allows you to push results into multiple parts one exception is working with parts that are within a sub-assembly in that case you just need to set the sub-assembly as flexible. With this functionality being so easy to use and the detailed information produced from it we should never experience design failures once we produce physical prototypes.

Inventor Tooling – Analysis Overlay

Inventor tooling has always allowed us to run a few different analysis on our plastic parts like:

  • Fill Time
  • Plastic Flow
  • Confidence of Fill
  • Quality Prediction
  • Air Traps
  • Weld Lines

When reviewing these reports in the past you had to look at each one independently.  When working with Inventor Tooling 2011 you now have the ability to use a overlay option that allows you to merge up to 3 different reports at once.  Let’s take a look.

Part Fill Analysis – Inventor Tooling

When working within the injection mold industry there seems to be a lot of money for someone to make. One area that does real well are the company’s manufacturing the mold designs themselves not normally for the first design but the rework to follow.
Autodesk Inventor tooling has some great analysis built into it that will allow us to:
Identify Part Defects—pinpoint the severity and location of potential manufacturing defects, such as weld lines and air traps. Then, make design changes to avoid these problems.
A part fill analysis evaluates an individual plastic part. Fill analyses answer the following questions:
1. Will the injection molding process produce parts of acceptable quality?
2. Which material should be used?
3. What are the optimal process settings?
4. How many gate locations are required and how will this affect mold filling?
5. Where are the potential defects such as weld lines and air traps?
After the analysis is complete we have the ability to investigate the following results:
Fill time result – The Fill time result shows the position of the flow front at regular intervals as the cavity fills.
Confidence of fill result – The Confidence of fill result displays the probability of plastic filling a region within the cavity under conventional injection molding conditions.
Quality prediction result – The Quality prediction result is used to estimate the quality of the mechanical properties and appearance of the part. This result is derived from the pressure, temperature and other results.
Air traps result – The Air traps result shows a thin, continuous line wherever an air trap is likely to occur.
Weld lines result – The Weld Lines result displays the angle of convergence as two flow fronts meet.
Having this easy to use functionality and others we can produce a better plastic part and overall mold design which will lead to much less rework and a better mold design the first time.

Injection Mold Gate Location Analysis with Inventor Tooling

One of the most important decisions in any injection mold process is selecting the gate location for your material flow into your part. Many companies do this by tribal knowledge or in other words experience. This might not always be the best way to make such an important decision with your injection mold design. There are many factors that come into play when making this decision like:

  • Material being used
  • Part design
  • Mold temperatures
  • Pressures to be used

and this list can go on and on. Autodesk Inventor Tooling can analyze your best gate location for you very quickly to make sure you are right the first time avoiding costly rework to any injection mold design. This is only one of the great and easy to use features you find inside Autodesk Inventor Tooling, let’s take a look.
