No, Im not talking about dildos.

I got a few things Ive designed, but the only effective way to have them made would be to have them moulded from plastic. (requires curves, so bending up steel is probably out)

I wouldnt have a clue where to ask for it to be done.

Anyone know how much it would cost?
expensive? (my guess)

Thing i want would be 50cm (max) wide,roughly 5cm high, 30cm at its longest. And needs to be hollow.

Anyone got any idea where i could get this made up?

Plastic things are injection moulded or blow moulded.
If you want it injection moulded it cant be hollow or it has to be open at one end. gonna cost a fortune couse will require a die made for it. If it doesn't have to be very rigid it can be blow moulded and will end up pretty soft similar to babies toys, they are hollow and cheap. Still done in mass production though. If it's a prototype of some sort dont make it plastic - the necessary equipment costs too much. If you've designed something that is completely enclosed, hollow and a single part, it can't be made easily. It has to be several parts fitting together, creating a hollow assembly. Not sure what you have in mind though.

We have this thing at my school where you have a wooden mould of it and you have a tray you put the mould on, then let that down, clamp a peice of Plastic over it, then pull a heater over and wait till its soft and pull the mould up into the plastic then turn on the vacum and it sucks it around the mould. Then you take it out bang the mould out and cut off the extra plastic. Its called a Vacum Former

i agree for one off or prototypes it can be big $$$,I looked at making a sort off off set hornet style scoop a few years ago and it was nearly as much as the car was worth. Could you try a clay mould? Then some fibreglass sheets and resin?

have worked in injection moulding for 7+years.
Hard to advise anything without knowing what you want but unless you had money to burn or a mass market for your product, getting an injection moulding die made wouldn't be cost effective and you'd never reap back costs. (ie:can easily cost $4,000 for a simple die)
Out of curiosity, can u give me an idea of what you have in mind?

Hmmm thought it would cost a bit, but not tha much.

JADED6, the thing i refered to is part of a air intake thingy.
Im bad at explaning things. PM me if u want

Will probably make one up out of fiberglass n see how it goes.

now for a crash course in fibreglassing :)

figured it'd be something like that, you can buy acrylic in sheet form very cheaply and bend it with heat but prolly not the sort of plastic they're made out of (me thinks talc filled poly propylene)

it wouldnt be possible to make it out of stainless would it?
