I would like some help with blow moulding or rotational moulding
(OP)
Hi
I am designing a display unit for one of our products. Essentially it's a hollow enclosure that is made of two pieces, the upper piece (dome) needs to be clear transparent. I'm thinking PC or PET, it does not have any structural requirements.
The bottom half (base) will support the top half, and will contain water and a pump within.
The display will allow our product "the scarecrow" to activate and dispense a high stream jet of water. The water will drain down along the inside of the dome into the base.
We need to make lots of these functioning display cases (like 500 +), and they need to be CHEAP!!! I am sorry to say that unless we can make the plastic for $20 US it's gonna be canned. That leaves China as the only viable solution to cheap plastic manufacturing.
Can anybody help me out here, I'm looking for contacts in China, a good track record, ect ect
Thanks

The biggest cost by doing business in China will be the communication and travel cost. On a small cheap project, the costs of communicating with China might be more than the cost of getting it done close to home. I guess home is USA.
Rotational moulding can be done on very cheap tooling, so it is probably the way to go, or even fabricating from acrylic sheet. Have you talked to a local sign maker who does backlit sighns.

You will probably have to find an accomodating vacuum former to do this, but anyone with experience in prototyping parts using vacuum forming should be particularly usefull.
If the size you are talking about is approx 400mm across then I have actually seen a similar sounding item used for sprinkler demonstrations at a agricultural show in New Zealand.

here's a pdf page with my design, can you have a look and see if it's feasable. Top dome maybe PETG or PC and base LDPE.

You should be able to find some info on the web about home vacuum molding using a vacuum cleaner and household oven, that can give you an idea of what could be done.
