Hi all:

we are looking for some blow molding simulation softwares.
can you give me some advice!

thanks

Thanks

And Would you pls give the more details!

thanks

O.K.

I am also looking for the latest information on CAE simulation software for Blow Molding. Surly by now someone has experience in this area. I have only injection molding simulation and now employer needs Blow molding simulation as well.

There are various types of blow molding simulation software on the market. Because this software is so specialist it is usually quite expensive.

Software to predict wall thickness change as a result of the parison stretching to the contours of the mold: Have a look at the site: http://www.t-sim.com/www/index.html

You can download the full working version, but only run their example files.

Polymer Training Ltd. Offer software to simulate the effect of process changes have a look at their site:

The software is called Picat.

There is a new blow moulding simulation software available. It is called BlowView and it is developped by the National Research Council of Canada.

This is also available.

Hello Sir,
Myself kessy and i read this Forums of
Blow Moulds and i like this topic because i also find this website which provide to us the information about the Blow moulds.
Thanks.

I have never used simulation software for blow molding. It is so unpredictable, the process.
Unlike Injection, that is a technique. I consider Blow molding, an ART !

So much is depending on the way to you set the processing parameters, the timers, delays, exhaust, pre-blow, etc and it all comes with experience. There is no short cut!

What do you expect from a simulation ?

One might say that the extrusion process itself is more art - there are so many variable.

Everything must follow the physical laws of nature, and if the physics of the process can be calculated (for example heat transfer) then you can simulate the process. There are certain things which are so complex or so far from a physical process (a person painting a picture for example) that it is truly an art. However I have even seen computer programs than can emulate the painting process, although true creativity is not emulated.

By developing models our understanding of the process is greatly increased. Some models have inaccuracies, and studying the inaccuracies helps to improve the model even more.

I work with and sell modeling software every day and use it mostly for screw design. I got into simulation after 20 years of hands-on working with the process. Modeling helped to explain things that happened that I could not previously explain. Even after another 10+ years of working on screw design with simulation I'm still amazed at what I am learning.

For the engineer that is afraid that his "art" or his job will be replaced by simulation software, it is just not true. I don't believe it has ever happened. Nobody wants your job; it is just too difficult with or without software. It takes a brave soul to tackle these complex processes, and most people are smart enough to walk away. (Took me a while to figure out why nobody wanted to do screw design, while I found it interesting.)

Like it or not; if you work on a process you make calculations, use models, and do simulations in your mind. It is just a matter of how complex a calculator do you want to use. Not all plastic processes have been attempted to be modeled, or successfully modeled, but we continue to learn.

B-Sim is an available blow molding simulation package.

B-Sim only covers part of the process. Melt making, distribution, filling, extrusion can be covered by other modeling packages.

This looks interesting;
