At American Injection Molding, we have working expertise in a wide range of resins and materials. Even more importantly, we have experts who can assist you in evaluating and selecting the material which will work best in your application.  Strength, hardness, rigidity/flexural properties, static dissipation and the most important factor-- cost...we'll assist you every step of the way. Below is a list of some of the plastics we routinely process.

Here are some materials we frequently work with, and their specifications*:
