How do you select the right injection molding material? This is a very difficult question. Making the decision even harder is the fact that there are over 300,000 different types of material available, and that number grows by 750 more every year.

Injection Molding SampleSome people think the best thing to do is just select the latest and greatest material that has the best properties and can take super high heats. They might think that their requirements will never exceed these properties and their part will be fantastic. This is almost never the case. When selecting resins, it is a good idea to contact your local representative whether it is for Sabic, Bayer, or DuPont. Let them know what your product is for, the conditions that it will be exposed to, and the colors that you would like it in, and they will certainly point you in the right direction. Most of the time, simple resins like: PP, ABS, PC, or PC/ABS will be more than sufficient for your needs. If you have an out of the norm requirement, resin makers can blend additives into the resins to meet your requirements. 

So how do you select the right material? Ask for help first or go to the resin manufacturer’s website, you will be amazed. Remember, it does not have to be the most expensive resin to be a quality material.
