After you have established an idea for your newly designed injection molded product, the next step, which is one of the most important, is selecting a resin. You need to address what the product requirements are and ask yourself some of the following questions:
- What overall strength does the part need to be?
- Is the part going to be bent or have an impact on it?
- What about tensile strength?
- Is the part going to be involved in some type of pulling action?
- Is weight a concern?
- What about the electrical properties?
- Does the part need to be flame retardant?
- Does it need to be conductive?
- Is it operating temperature critical?
- How about chemical resistance?
- Specifically, does the part need to be resistant to certain chemicals such as alcohol, gasoline, oil, etc.?
These are just a few of the many considerations that need to be addressed when selecting the proper resin. It is always best to consult with a professional such as Toth Mold/Die Inc. who is knowledgeable in this area to assist you in choosing the proper resin for your newly designed injection molded product.
