I know that it has nothing to do with electronic circuits, but I am sure someone in this forum have ton of experience in making plastic. I am currently designing a programmable light signs. I have all the electronic circuit and concepts of what the final product going to look like. But I don’t have much knowledge in mechanical, just downloaded AutoCAD and playing with it for a bit last night.
I guess my question is…
Where and what company can turn my autocad design file into a actual molding?
Where can I get the plastic manufacture once I got the mold?
How much do they cost, for both molding and manufacturing. (the design will not be too big or complex, probably 7”x4” )
Oh and one last question about electronic…..
Is it not safe to operate light sign at 48v DC in a long run?
Because I have seen most of the sign out in the market is running off 12v DC.
And what are the benefits of running LEDs off a 12V DC? it will actually dissipate more power in the resistors, right?
Thanks in advance
