As part of its Moldflow lineup, Autodesk also offers Moldflow Insight WS. This lets plastics engineers tap into the scale and massive computing power of Autodesk's 360 cloud-based PLM platform to access simulation capabilities on an as-needed basis and to solve multiple scenarios in parallel without having to build the costly hardware to support it.

The other Autodesk plastics-related enhancement is the commercial release of Project Krypton, a simulation capability (which we've discussed before) that plugs into CAD software to serve up real-time feedback on part design, including how design changes affect manufacturability, cost, and sustainability.
Now officially called Autodesk Simulation DFM (Design for Manufacturing), the tool is powered by Autodesk Simulation Moldflow and works within Dassault, SolidWorks, and PTC Creo CAD tools. It delivers real-time feedback as designers work on their designs, using familiar indicators like green, yellow, and red lights to identify potential problems. It also delivers information about the source and location of a problem, so it can be addressed early in the design cycle.
SolidWorks' entry into this space is SolidWorks Plastics, a module that runs within the SolidWorks CAD tool, so engineers and mold makers can operate within a familiar environment to optimize plastic molds and parts for manufacturability.
This is a great example of intergration of CAD and analysis to promote manufacturability. I am impressed with the real-time feedback aspects. It will reduce design cycle times and allow more consideration of sustainability, manufacturability and other desirable features.
@Naperlou and @Tekochip: Sounds like you both are on the same page as to where this kind of CAD/CAE integration can pay off in terms of optimized plastic parts design. The whole value proposition is having this insight earlier on in the process so there is less rework and less wasted time going back and redesigning. I'm sure we'll see a lot more capabilities in this space as injected molded parts are on the rise.
@Chuck: You're right in that the goal of taking weight out of a plastic part is much like FEA, but this particularly type of simulation is really designed as a complement to FEA. It's focus isn't just on structural integrity, but rather about being able to design a plastic part and mold that is manufacturable and manufacturable in an optimized way. I suppose some FEA principles are supported by the tool, but it's really designed to highlight possible problems with a design prior to the finished design in the hopes of eliminating the need to rework expensive injection molds at the last minute.
Charles: In the SolidWorks press releases and documentation they do continually mention optimization. I agree with Beth that this is most likely in a reducing weight, cost, etc. type of way for the mold and molding process rather than actual FEA functionality? Especially since this package is completely seperate from the SolidWorks Simulation package which incorporates all FEA functionality. Since I don't believe Simulation is a requirement before buying Plastics, any FEA functionality would have to be completely inherent to the Plastics package - I.E. Plastics can't piggyback the functionality of FEA if you don't have FEA installed.
That being said, of course if you have Simulation and Plastics, you have a very strong package for developing plastics and molds. FEA could come from your Simulation package and refinement and modeling from Plastics.
This is a great feature in a design tool. It's so very difficult to create a design that works well, looks good and can be molded. You'll still want a mold guru to review the design, but having the tool review your work is a true value added.
Wish there was more detail about SolidWorks' plastic CAD features. Autodesk seems to get the lion's share of this article. Our company is interested in transitioning to plastic parts instead of machined parts and I use SolidWorks, so I'm looking forward to any features that might natively support injection molded part design.
These simulation tools are great additions to the CAD products. Moldflow used to be relatively cumbersome due to the limited modeling capability of the software. Now using the same CAD software that you use for the part design to run the analyisis is a true timesaver. It also allows the part designer to look at multiple gating locations on the part and see how the plastic flows in the part before steel is cut.
@Tim: I think you hit on the primary benefits of this kind of integrated CAE/CAD technology. It's really about streamlining the workflow and making the high-end analysis functionality accessible in an environment and within an interface that makes sense and is familiar that is so compelling.
I'm liking the enhanced long fiber analysis option. Many times when we use blended plastic compounds with these fibers, they can be a little bit unpredictable. It would be interesting to see how well this analysis matches the actual results.
So it appears that SolidWorks Plastics will be a package on its own; an addition to the Premium/Professional SolidWorks packages that already exist. Much like the Simulation package for FEA and heat transfer analysis. Is this correct?
It's great to see SolidWorks expanding the options here. I'm sure we will be seeing a CSWP - Plastics exam coming out soon.
New versions of BASF's Ecovio line are both compostable and designed for either injection molding or thermoforming. These combinations are becoming more common for the single-use bioplastics used in food service and food packaging applications, but are still not widely available.
For industrial control applications, or even a simple assembly line, that machine can go almost 24/7 without a break. But what happens when the task is a little more complex? That’s where the “smart” machine would come in. The smart machine is one that has some simple (or complex in some cases) processing capability to be able to adapt to changing conditions. Such machines are suited for a host of applications, including automotive, aerospace, defense, medical, computers and electronics, telecommunications, consumer goods, and so on. This radio show will show what’s possible with smart machines, and what tradeoffs need to be made to implement such a solution.
