We are doing this type of "bridge" tooling on a weekly basis. We are
injection molding non-reinforced PVC, ABS,Polypropylene, etc for 5-25
parts. Additionally, we are using LOM and SLS-nylon and SLS Rapid Tool
as tooling insert materials for injection molding with encouraging
results. However, with some complex part geometries/shut-off
configurations we still build aluminum tooling for our prototype samples.
The important thing is we are able to get material-correct prototypes in
days.
The SME RP and Mfg Conference (Detroit, Michigan, USA) in April 1996 is a
good source for papers on this subject. Their web page is
http://www.sme.org. The contact for this conference (and proceedings)
is Lori Hastie at hastlor@sme.org.
