Hi Franck,
My PhD research at "Centre for Rapid Prototyping in Manufacturing" at
Nottingham University is on SL Injection Moulding Tools. I have
produced different ACES injection tools without using cooling
channels.
My present moulds have relatively fragile features in geometry to
intentionally make them more voulnerable. However, on my first ACES
tool I got 260 shots and on my second tool I stoped after 500 shots (
I had no more time to run the tool) without any tool failure. I used
Polypropylene material. So the results are quite promising.
I presented my first paper on this subject at the Second National
Conference on "Rapid Prototyping and Tooling Research" at
Buckinghamshire College" on Nov. 1996. I hopefully will present my
second paper on this subject in coming " Sixth European Conf. on
Rapid Prototyping & Manufacturing" at the Nottingham University.
I hope this would help you now.
cheers
