injection mold

[pecopepp]

Hello, guys.
I introduce myself to myself, neophyte of injection molds.
I should start... with a relatively simple mold according to my die friend... we say it occupies a surface 300mm x 400mm.

Now I'll throw it big.
to not start from 0 there is someone who could send me a mold even without matrix and punch, then I put it... Well the dream would have it in *stp or *igs naturalmnte I need it just to see it, to understand, in fact, to start.

Did I ask too much? Don't treat me wrong...

p.s. in addition, you can suggest some things to read or some site where you can read some technique... ?

 

[pecopepp]

No new ones?
Not even a book?

:biggrin:

Not even a book?

I can assure you that the only book I have is my goat and so much experience

Maybe there will be manuals explaining in "maximum line" how to proceed with a mold project, and that however that each component has its characteristics... Don't be discouraged. It's a beautiful world.

Hi.
for many years I have been working on molds and all the problems (but also satisfactions) that this profession leads you to face, the problems given by how to heralize the mold, the construction in all its stages and not least to make it work well, know how to perform the next targeted maintenance, the mold in the moment of construction really costs nothing, what it costs is when it works as it works and how much you will spend for its maintenance.
In addition to the direct experience that you have to have more mechanics in general, you must surely live this craft in a direct way, apply the mechanics for the construction of a mold means to apply everything that is mechanics in a complete way with the addition of what they do not teach you.

said this a designer should be able to pass first on the constructive side, understand everything that is to know and know about the realization, in this case, it
mold and then you can start pretending to design.

there are definitely books that can help you understand but you have to find the way to get in direct contact with those who build, there are companies that organize courses, internships, where they also teach you to print.

if you have time try to navigate the hasco site (produce normalized for molds) if this site is still as I remember with a registration you have access to a simple program to use online, where you can create the mold according to the normalized pieces proposed by the site.

or look for from a search engine "normalized for molds" there are many companies that make available drawings of molds, perhaps not manipulatable but that give you a half idea of what you have to have to do some small step forward.
having you a die friend, you have to ask him to help us.

I recommend some targeted courses, always on the net find what it does to your case.



Greetings.

if you send me the product with the withdrawal(iges) +n .impronte , if they are dx + sx etc.
and the type of injection required I will do it to you (just I have a little time)cerbonym[COLOR="Red"]at[/COLOR]valtiberina.it

 

[SHIREN]

ciao, you must surely live this profession in a direct way,
un saluto.

I just need to add
the craft you learn from young people
when the other coetans go to sunbathe

and I repeat what you have already transmitted
I'm a trade you live in the quodidiano! ! ! ! ! !
Thank you very much

 

[pecopepp]

in time thanks to all for the consigni and encouragement.
the fact is that I am not really fasting, for 3 years I have made stamps for tip and defornation, precisely for this reason I also needed to look at one more or less of the same size. cm I will try to put in pretica every vs. advice.

 

[pecopepp]

Guys...
for whom of you is in the deck of cards, will not dare to touch xxxxx and make a price....
I unfortunately never made injection molds and my friend who put the workshop is always and only been in the workshop... so today we are busy with a quote. . .
Consider that the workshop leads it alone, I am of support almost in favor.... waiting for better times;-)
with what price could you come out? keeping us tight... ?

Thank you.

 

[stang64]

for what you can see and understand from these photos, a "cold injection" mold to one figure could be between 13 and 15 thousand euros. If you have to or you want to propose a multi-print mold, the size and the price becomes more important.

at this price you have to add the material for the construction, the normalized, if you need the tempering of the material in the print areas and a small percentage of error you could also count.

steel inserts, I don't understand if they have to be overprinted or if they can be inserted later, otherwise the mold must have some extra adjustment if the material has to be overprinted.

as indicated also by cerbonim you need to know the material with which you have to produce it, this also to know what kind of material you use for the matrices.
if you need to make a few pieces the mold could also have another type of cost, the right and left piece could be done in two times producing first one (right) and then the other (left) making a matrix change, depends what kind of productivity you need to maintain and what cost you have or will have the printed product.

Greetings.

Then:
1) steel inserts must be inserted before.
2) the number of pieces to be produced and fixed at 1000.
3) no mirror polishing is required, no particular steels or special treatments.

plastic still failed to know the name, but I say it is the "most common" (but I repeat my ignorance in terms of injection).

cm still thanks to all

hello pecopepp, I read the discussion until this post, if the mold has to produce only 1000 pcs. you might think of building it in aluminum considering also the fact that if there are no special treatments or surface finishes like embossing etc. you would certainly have a benefit in terms of cost.
for such limited drawings for example ferrari uses for objects that will then be covered in leather and therefore that they do not have special finishing requirements technologies used for prototyping (without building the mold).

Good luck with the quote!

 

[stang64]

Well, let me give you some more info that maybe you could use:

the mold will have to be thought to have the possibility to receive inserts in shaped housings and then perform over molding.
for 1000 pieces it is possible to use a reclaimed steel without thermal treatments.
If common material is spoken, it may be a pp or a pa, these have a shrinkage that varies from 1.0% to 3% depending on the thickness and cooling (and also the material used for the mold).
the withdrawal percentage changes if they are common materials like these but loaded to increase the mechanical characteristics.

I would stay at a mold with only one figure since they are only 1000 pieces.
If you have a mold that already produces other items I would try to accommodate them also using the same carcass of an existing mold.

Say hi.

Hello pecopepp
they have already responded to you with a very good assessment
But if you're two in a workshop
big way in the country
you could also get down to a lot of nu 40-50%
you're doing it.
Then it depends on when you want to take home
Thank you very much

working on us na 15gg the job you do it... .

Are you kidding me? ? ...for a mold?...is not too many?

 

[cerbonim]

for this mold are too many, for others I have seen
more than 500 hours of design (book lamps etc.)

1 (one) only operator!!! ! ! ! ! !

[Mould Inventor]

I've already done a similar mold, considering you're alone.
one day project
a day drawings
a day fresi matrice and punzone,niente sgrossatura, prefinitura and finish
one day do the cooling and extraction/injection
a day castle extraction
a day polishing and assembly
6*8 = 48 hours * 45euro = 2160 European labour force
hours m.24 hours * 45euro= 1080 euro

more materials, I recommend normalized and everything from full, another 5/6000 euros,
up to 10,000 euros not more!!!

 

[stang64]

the roadmap indicated by mould inventor is in my opinion a little 'straight' even if the product seems to be quite simple I think that a few more hours, both in the project phase and in the realisation phase you have to spend and perhaps you have to consider (and put into account expenses) some intervention after the first phase of printing of the product.
inter alia the metal inserts must be inserted and laid in the cavity before then this time of a machine operator must be considered and recovered in the cost of the mold or in the cost of the article, normally for small series of pieces you try to stay with a cost of the right piece and you tend to recover the money in another way.
We say that by reading a table of realization of this kind, everyone wants to design and make molds but, in the reality of things a lot of way you have to do and some time more you have to have.

Greetings.

a little tight is it, but for 10 years I am always tight and never enough:frown:
As for inserts and time for molding I do not consider it, one because I do not mold but realize only the molds, two because you do not refer to this.
then for the mold test the price varies from die to die and any subsequent changes if I am my fault I have to arrange otherwise they will be die removers, pay and arrange them :mixed:
