We've mentioned IDES in these pages once or twice before, but an astute reader has pointed out that in addition to selling content and supplier info, the self-described "Plastics Web" portal also offers a pretty deep collection of expert articles on a wide range of plastics selection and design topics.

The Plastics Design section offers 30-odd articles on subjects from snap-fit design to replacing metal for lower part cost, and a greater array are available as downloadable PDFs at no charge (though it looks like you have to register to enjoy such classics as "Victrex High Performance PEEK Polymers for Food & Beverage Processing") Some of it's pretty dry and esoteric, but the more general ones, like Steve Maki's guide to thermoplastic selection, can be godsends. Great for avoiding dumb mistakes before engineering calls bullshit on your design.

Thanks Michael!
