Choosing the right material for your custom plastic injection molding project is an important decision. Before choosing a material, you have multiple items to consider: Part function, application, durability, flexibility and color. Plastic molding materials look and behave differently, so your material choice affects your part’s performance and characteristics. Even the material’s shrink rate needs to be considered.
If the plastic injection parts are molded out of one material for the initial production, changing material for future production runs may affect the part’s dimensions. That’s because different material may have a different shrink rate.
ICOMold’s plastic material list contains a wide variety of materials to use for plastic injection molding. We also welcome your requests for specific resins. If you need a material that is not listed, please let us know and we’ll do our best to obtain your specific plastic resin material.
By visiting the plastic injection molding material list, you will be taken to an external website with a searchable database of plastic materials. The chart specifies the injection molding material grade, characteristics, sample applications and other details for each material. In addition, many of the materials listed include a downloadable PDF material data sheet.
Use the search box in the upper left-hand corner to search the entire database, or narrow your search by checking the boxes that meet your product’s needs. Those requirements include items such as “UV Resistance,” “High Impact,” “Fire Retardant,” or “Food Grade.”
