When material properties are not available with available resins, custom material blends can be created to improve the performance of multiple resins. The use of additive reinforcement materials can increase Plastic Injection Parts strength and stiffness, thereby reducing warpage and shrinkage. Additives such as glass or carbon fiber can be used to enhance part performance and improve flow, sprayability and dispersibility.
One of the most important steps when preparing an injection molding resin selection is to create a comprehensive material selection list required by the product. The list should most likely include price targets and resin supply-because resin supply may pose risks, consideration should be given to choosing a spare resin. The types of resins available, part appearance, part strength, environmental factors, regulatory requirements, and whether or not additives are needed are all important considerations that should be carefully weighed before starting an injection molding project. Also, it's always best to look at the specifications of the generic version of the polymer, as the properties of these materials may be very suitable for your application.
