info realization injection mold

[genioz]

Bye-bye.
I want to point out that this is my first approach with injection molds, I am quite inexperienced in the matter.

I should make many small caps (18mm diamentro and a height of 15)

these "tappini" are cappucci led cover, they must be completely transparent crystalline on most surface apart from a curved area inside that it has to be finished readrmete opacized for light refraction!

I would need a small size mold
some cheap company that realizes souls
a company that moulds

at the moment I would need a small limited circulation of 1000 pieces about after that the quantities could rise

Does anyone know how to recommend a good and cheap company?

I live with rhymes.

Thank you.

If you're still interested, we can get along.
the circulation is certainly little for the almost totality of the enterprises of the field. I have a technology more suitable for your needs, always in injection, from project to product.
Bye-bye soon

can you give more details to the benefit of the forum?
Thank you.

I certainly do injection moulding of thermoplastic materials. I also own a miniature machine for microprinting. the convenience is that the mold has much lower costs even if the times increase. Obviously the proposal of our friend on a traditional machine, as you will have understood, is not feasible. in those cases there are no solutions seen the complex in the material (transparency and opacity) unless millions of them are made or sell each to 50 euros.
microprinting lowers costs but is not very used as the machines have a high cost than the exploits, do few prints and you should sell in detail to earn money.

It's all feasible, even with "traditional" machines.
I am responsible for this sector (also) of transparent and opacised parts and of
lights for automotive industry (also electrical appliances etc... )
There are many possibilities. There are also many solutions for presses.
I would say that a piece measuring 18 mm high diameter 15 mm is not unusual at all.
I believe that the problem should be set in a different way; i.e. geniusz I think it is more useful to study a proper geometry for the light diffusion that does not immediately refer to the finishes. then this speech will come.

I agree that the imprint has nothing special, very feasible, the unusual thing is the pull. I would like to see who takes the cost of a possible mold that does not have market for 1000 pcs. more feasible would change one already present.
Mah. if there are other alternatives would be an interesting discussion, at least instructive!

 

[Jari]

as is set the speech you are many alternatives (troppe) .
So let's say that to make some conversation:

take 2 cases limit one very cheap and quick, one instead more refined and obviously more expensive.
economic situation
the customer wants a polycarbonate cap with 4 polished faces and an electroerous (internal) to opacize.
no light-optic study, the piece is glued to the support (will have a support ?), no clip, no movements
on the mold, no inserts on the mold. only one pin (from catalog) for the soul and a fast polishing process on
matrix obtained from the stand (economic also because of size type 156x156)
mold with a footprint, molding on a horizontal press (in a press day more than 900 pcs).

2nd case
the client asks for a study, does not have a defined mathematical model can tell us only where and how he would want to hook the hood.
you need to do a study for clips or something like that, develop a mathematics (maybe relying on something already existing)
for speech refraction and do a study of light-optics.
but it is not necessary to overlook the led which can cost quite a lot depending on the characteristics, even here there is to be evaluated and it is not said
that you can change it. also you may need to develop a prototype and check shadow zones etc... (especially check the simulator data) but it is not easy
make a prototype with the same characteristics of the printed piece, so it would take a prototype only to do the tests and then make the final.
probably the prototype mold can be used again to make the final.
Moreover the pull was limited, but from the speech just mentioned there are also margins of greater pulls.
So, probably 2 prints, but how and where do we inject? Do we want to put a hot room with two nozzles injecting into the figure or do a cold straightness (with injection point on a shiny face?) ?
these are all variables that affect not little on the costs of the mold.. .
Finally, for the question "who is the cost of a mold?" the customer .
but of course (unfortunately) always depends on who the customer is and who the supplier is.
...this is another subject. . .

ah I forgot, another variable: the supplier may have a design study (both lighting and molds), have
molding and workshop molds. or there could be more design studies, a molder and a printer.
So even here things are still complicated.

That's why when you want to make a "new" product (new by way of saying) you start with the money you want to spend.
