MOLDING MATERIALS
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 a different material may have a different shrink rate.
A list of the most commonly used injection molding materials is given in the table below.
