design tips, materials, molding

[Mau89]

Good evening to all, I am new to the forum and placed here because I did not know in what other section to post this question

with my activity I am looking for the best method to produce a "case". This is a cover that will cover an electronic part of the cubic size of about 30*30*40h.

I own an extruded/expanded polystyrene mold and I have the possibility to create one in wood and I thought the best and fastest way is the thermal mold (it is called so?) but I read that the injection mold is also used. I would like to understand what might be the mile method for realization and to whom I can address

Then another question about the design, for now I have dealt with the realization of the mold without using design software, I imagine that from now on I will have to take advantage of it and wonder what is the best format etc.

I have also done a search for materials and among the many I care about the pp or pvc, but I am available to understand what other materials would do to my case for the realization of this model that must be at the reach of leg (of dog:bekle :d and above all precise that it will have to be susceptible to replica "easy and fast" for the marketing.


greetings to all and best wishes of good holidays

ps sending an enclosed prototype in the phase of realization that I am doing in fiberglass, is composed of a base and a case that must be placed on the base

Bye. that confused phrases and without punctuation. Let's see if I understand....

we are in the mechanical sector so the units of measurement are the millimeters and not the centimeters.

you want to make in several specimens a kind of empty box in plastic material.
You never used a 3d cad.

then as for im model to give to a molder is usually a step or iges.
to have an effective cad model, you must also make the table. so you need to buy a license from a 3d program that suits you or choose a free cad that is complete.

you could do the object in rapid prototyping with a 3d printer. if you want to make in series you need to make a steel mold and to injection print the object. the numbers must be high because the mold costs you more than 5000€. then the material, the press, etc. etc. are paid and to shock you have to make a big lot.
materials are not all the same and must follow regulations for the sector you use.
It's the case that you're worth it. we are not inventing ourselves from today to tomorrow designers or builders of things that have never been handled.

hi mechanicalmg, sorry punctuation but writing from the phone is already so much that he managed to "make me understand".

I'm turning to you because I'm not in the industry and I didn't want to improvise. I asked who I could address both for the design question and for the mold and injection.

At this point I make a premise, this tool is/will be a croccantini dispenser, the purpose is to make it deliver a few at a time (from 1 to 3 crocchettes).

I've experienced a dispensing wheel with individual housings in which a single mouthpiece stands.
problem: limited amount of food

I partially solved this problem using a cereal dispenser:
the problem of this object is that it releases more than 2/3 bites and in very variable quantities. How could I get to this situation? Do you think of anything?
I thought of miniaturizing it, but also getting the effect of the least dispensing I still have a quantity of food emitted very variable :

suggestions?

Thank you very much

first thing you have to understand what you want to deliver, size etc. I imagine granular croquettes about 8mm.
of mechanical systems to make mechanisms there are many. It is not said that it must be a turbine-type blade impeller. it could be that you can use an endless screw, or a two or three-position drawer, or more complex a load system that goes on a weighing plate and reached the weight discharges it in the bowl.
sure you're risking patenting and/or copying something that already exists. If you do it you have to think about all the problems and above all that logic has to follow.
first the mechanism must work before thinking about the mold and the non-toxic materials to be used.

questions:
- dog-driven dispenser? if you can operate it all the times you want without the master. Is that what you want? or in 24 hours should not be provided more than x grams?
- if it has to be automatic, the electronics are required on board. must be reliable or the dog dies of hunger
- this object you will realize will be competitive and functional? Look what you find http://www.google.it/search?q=eroga...ved=0ahukewi75tki15xkahwfqw4khsl4apwq_auibigb and they're all automatic.
Are you sure you get rich or at least cover your expenses or go blind and risk your investment?

ps. I also write by phone but punctuation I use

 

[Mau89]

when delivery you decide it through your smartphone.
croccantini range from 0.7 to 1 cm to maximum.
I've focused the endless screw and I like it, I'll test with the meat grinders.
What about the drawer system?

Is there anyone here on the forum who does this kind of work on commission?

 

[meccanicamg]

the drawer system works a bit like the palette impellers. You've got a two drawer drawer. the first is full and translating on the drain trap while the second is placed in the load. with the alternative bike pick up n drawers full of material.

however the screw of the meat grinder is more efficient

http://www.elantas.it/elantas-italia/prodotti/resine-per-modelli-stampi-prototipi.htmleverything can be made in resin
or better in resin wood
and you can also pull from the different matrix dozens of printed
it would be logical to turn to a modelling
making industrial templates and prototypes
Thank you very much

Mau89, I wrote you in mp

per mau89: save in mp

In principle I agree with you, the mp message I sent to you, contains confidential information notes (otherwise that you reserve would be?? ? ) that I cannot publicly disclose but that, also, they can avoid unpleasant consequences to the user. This is essentially patent issues.
