I want to produce about 1,000 durable cases for wearable.

 

  1. From where can I hire product designer?  I need a beautiful case to contain my electronics.
  2. Is 3D instant plastic moulding case durable enough for wearable?

 

If I  have no more new popular product in the coming year 2022, I will become very poor!  crying

 

Nowadays, no one can enter China.  The only way to produce beautiful case is by 3D-printing in local shops.  no more local metallic pressing shop.

 

Please help.  crying

That sounds awful, what makes you think they will print beautifully?? Maybe just OK without a lot of finishing steps.

What enclosure companies have you already contacted for customization to your specifications?

What are your specifications ?

From where can I hire product designer?  

 What are you talking about??? Where can you get tires or a yoga instructor?  Design firms are all over the place.  This is a weak question at best.

What have you done so far on this so-called product development?

Have you developed actual products before, or is this a startup operation?

When in the dark remember-the future looks brighter than ever.   I look forward to being able to predict the future!

What weak question?!?

It is my first hardware product!  I already have a fully working board.  I need a beautiful case, better in aluminium which is resistive to corrosive human sweat! crying

 

Wuhan virus killed my touring related business!  Now, I need some new popular products!  crying

 

We can't travel and visit factories.

 

Factories and shops in China are folding in series.  Sending money to them is a very high risk nowadays!  Today, there is a factory. Tomorrow, perhaps it may become a bank's asset.  crying

cases for wearable

What does that mean?? maybe these will do ??

 

 

If you are serious about bringing a product to market, locate a good fully itegrated contract manufacturer---there are many many many .  They will do a lot of legwork for you, especially when you have no experience making anything.

This one is closer to my idea.

 

I want aluminium case as it looks more deluxe but plastic case is safer to kids.  angel

 

There are cardboard package designers in Hong Kong; so this procedure is easy.

How much are you willing to pay per unit for the cases? Reason I ask is that I have one of these... 

 

TTGO ESP32 Watch

 

Sure it is £20 but for that you not only get (apple like!) watch strap and case but an ESP32 Arduino/Python programmable WiFi CPU and quite a reasonable touch LCD so if you could re-use some of those as well as strap/case it could be cost effective (and £20 is the one-off price, these Bangood dealers are bound to offer a bulk deal)

 

Here's a YouTube video that does a better job of explaining all the watch features better than I can...

As they already built,only 1-2 US$ each.

I have a working air quality monitor prototype based on BLE.

 

I want it in the form of watch or similar size.

 

Next is the PCB and antenna, and enclosure.

 

 

Finally, it is the media, video, photos, etc.  Who can do attractive advertisement grade media for me?

Many of those on freelance sites are scammers.  I tried them several times.  Nothing was done even I wanted to pay.  Site admins are impotent dealing with those scammers.  no

Those EM simulators have come a long way, though the price can still be pretty costly!

Antenna 3D modeling is a rather sophisticated area of electronics, not something you randomly "hope" to get answers from.

Even the modeling software requires a lot of electromagnetics insights into using it effectively. 

It's like a good circuit simulator isn't a save-all tool if you don't know essential circuit techniques--you need to have some decent design to simulate.  The garbage in , garbage out rule becomes evident.

For antennas, prob best to start off with some known working examples--since their particular theory of operation has been explained, so you go in with a heads-up on characteristics.

Yes,I used It since ‘90 from DOS modeling for Yagi,Quad and etc.Special purpose Antenna simulators are free.If only one kind of Antenna,Example:only microstrip or patch.But with variety Antennas Simulator Then IP must bought(a.k.a complete program)

I will not know who is located near you---You should first try looking in your local area---there should be plenty of designers, as well as contract manufacturers.

Contact your sales reps (for the different components you use), they will know companies doing the work (the sales rep accounts) & they will be able to make their recommendations.  It is their business to know who's who & what's what in the area.

You have to be willing to do legwork & establish connections & relations with vendors who will support your needs.  Someone you can visit is ideal, especially when you are just getting going on your first go-round.

When in the dark remember-the future looks brighter than ever.   I look forward to being able to predict the future!

If you had Nuclear Power plants why harvest far away Nuclear power plant very inefficient ??

Did OP will export also ?

My wearable power supply is almost finished.  It is expensive indeed.  no  sad

 

It is an important part of any auto-powered wearable.  Goal is to get rid of any battery replacement or maintenance.

 

Auto-powered design is a little bit tricky and expensive.

I guess you need to hit the road and start searching. Since you are allergic to China, I'd search Taiwan, S. Korea and Japan for manufacturers.
