alternative a moldflow

[Geppetto82]

A lot??? ? but that we are crazy.....I am approaching the world of plastic injection I have already designed and made to make some straight mold.. . now I am following 2 that will go to hot room and the various suppliers I am contacting tell me that they will perform filling analysis (price to them said free....with all the money that cost the hot rooms....).

 

[TECNOMODEL]

Of course they do the analysis to you, if they want to give you a room that works....
now all the manufacturers of rooms have the software, and it repays widely.
think if the molding isn't good, everyone pointing their finger on the room. In that way, they are careful and can verify that the settings are respected.
I repeat, if one has a good volume of work and quite demanding products has no problem buying it.

always that the "colpa" does not fall on the moulder and/or printer......

I will soon review our advisor try to ask for more info so I can tell you....

I had the opportunity to try Moldovaflow, Moldovaex and visiflow.
Moldovaex is definitely more slender than Moldovaflow as use, but a little at a time at every release they improve something. has as advantage that, as a Moldovaflow, it is possible to create a three-dimensional mesh, choosing the number of layers inside, since you can increase the number of knots infinitely together with the calculation time. output parameters are comparable to those of Moldovaflow and also results. I find it very convenient that they propose very often webinar that update on the state of the art of the software and that often present concrete examples in which you can always learn something new. Of course, being 99.9% of their Korean/Chinese developers understand their English is not always very simple.
visiflow is much more "raw", but as for me the results I get are of simple interpretation and are also quite reliable, although less accurate than Moldovaflow or Moldovaex. visiflow mesh is not only built on the skin of the component, and it is not an analysis that takes into account the knots. it is necessary to be a little careful to the thickness of the elements, however, not being an analysis dependent on the knots is decidedly faster.

currently there is also solidworks plastics (they bought sympoes years ago)
Many see badly visi-flow (it comes from bertacchi software or I remember badly?) because they say it is not reliable (no 3d, at least in automotive you are screwed) but on this I have no direct experience so it may also not be. on a benchmark required in 2012-13 at the visi the results were poor
Moldovaex v15 has an interface now "human", indeed as workflow resumes that of Moldovaflow (it seems to me that currently do it a bit all competitors). Moldovaex we have used it for almost a year, for a few cases made it seems ok

 

[nuvolanove]

ah there is but inarrival also sigmasoft sigma (it really is so much).
Moldovaflow is now renting like all autodesk but stimo on 10k euro per year for an insight that arrives at warpage

low estimate, you're about a third of what they ask.

 

[nuvolanove]

and say that in 2015 autodesk simulation (structural+cfd+moldflow with cloud solution) for a year we had been offered to about 12k euro
It's always nice to see that prices rise. . .
just before you switched to rental licenses, buying the license (Up to warpage + interface)
offered it to 60k euro. then there was annual maintenance obviously.
It seems to me that the purpose of renting licenses is to provide autodesk more earnings on time from 3 years on...

 

[TECNOMODEL]

now more or less an annual rental license costs 1/3 of how much it cost to buy a permanent.

Moldex3d www.moldex3d.itGo https://www.moldex3d.it/it/approfondimenti/approfondimenti.aspx and find everything you need.
However for me, today, Moldovaex3d is best-in-class technology in its sector, now much more performing than Moldovaflow and even less expensive both to buy it and keep it.
treats very advanced processes where Moldovaflow shows difficulties ( foaming, rtm, smc etc.ecc), also on gas is much better.
it seems to me that all hot chamber manufacturers have addressed Moldovaex3d because of its ability to operate in a completely 3d environment (see blm boundary layer mesh), which is fundamental in the simulation of the dynamic movement of the pin in the chamber

we also arrived at the tiring Moldovaflow renewal or switch to Moldovaex3d. Obviously to use Moldovaflow push for that, but with the prices they do and the bond of the license to rent for 3 years is really hard. to repay it I think you should have a continuous flow for 365 days a year, which is only feasible for hot chamber manufacturers.

I see you use visicad, have you evaluated visiflow?
you would have a single instrument.

we tried visiflow at the end of 2015 for test.
Obviously the only environment is advantageous but it is not so true. to do the analysis, they needed a lot of steps from external applications, the results were not satisfactory. was developed further?

 

[TECNOMODEL]

I don't know, I had made a valuation between Moldovaflow, visi and Moldovaex, but then nothing happened.
the amount of work does not allow to shock the cost.

 

[barabotto]

as someone had suggested above, an alternative would be to consortium various companies (absolute utopia) or avail themselves of various services. the point is that those who do the analysis as a service will never fully meet the needs of the program internally. Finally, you could increase the amount of work by proposing yourself as an external service.

Meanwhile I am curious to see what will decide our property. already at the beginning of the century made the great purchase of the famous program that at the time cost as much as a nice apartment to which to add a pc that supported it.

 

[Meteor02]

I use plastic solidwork and I find myself very well, until now the simulations have turned out extremely accurate, the cost is not prohibitive and helps a lot in the design phase both of the mold and of the particular

 

[TECNOMODEL]

is plastic solidworks integrated into solidworks?
If that's how it compels those who don't have the cad to buy it.
What does he do?

 

[barabotto]

what do you mean?

 

[Meteor02]

plastic is included in solidworks I do not know if it is installable separately.
I use it to analyze the printability of projects invited by customers, helps to identify the best injection point, size the press and cooling, locates the joints of material due to the direction of the flow and possibly how and how the piece is deformed during cooling.
by precise analysis I mean that often after making the mold project we have made a simulation to the suppliers of hot rooms and the results have always been practically equal, and once produced the mold also in production we had the same results of the simulations.
Obviously it is only a valid support to the experience otherwise it becomes even counterproductive to make dozens of simulations that employ the hardware even several hours before giving a result.

said so it looks very interesting this product!
