IDES has assembled a very nice collection of free plastic design guides and articles that you should consider downloading for your personal library. Just add them to your cart and they’ll send you the link. Here’s a few I found really useful:
Designing With Plastic: The Fundamentals from Ticona is a classic (if there is such a thing in plastic design guides). Last updated in 2006, this single guide presents all the basic information regarding plastic and part design for injection molidng. This is definitely a must-have.
The Design Solutions Guide from BASF is also a very complete review of the subject. Is it better than Ticona’s? Download both and see for yourself… they’re both free…
The Snap-Fit Design Manual from BASF is just that: It reviews all the ways you can snap parts together including the fairly easy-to-use stress calculations for each (to make sure you’re not over-stressing the plastic).
There’s 66 articles in total, but you’re probably not going to be too interested in some of them (like Cold Jet – Industry Overview: Plastic Mold Cleaning or Effective & Economical Purging of Plastics Processing Machinery). But you should check out most of them… again, because they’re free.
In addition, IDES has a really decent collection of free on-line articles covering design, materials, processing and other related subjects. All you have to do is register (for free).
