The thermoplastic injection molding is the most widely used of all plastic processing methods. As soon as being formed, thermoplastics can be heated, reformed and recycled over and over again, reducing waste and saving on material costs. The high quality injection mold is essential to a project's successful completion.

       Most polymers, sometimes referred to as resins, may be used, including all thermoplastics, some thermosets, and some elastomers. The available materials are alloys or blends of previously developed materials meaning that product designers can choose from a vast selection of materials, one that has exactly the right properties.

       Materials are chosen based on the strength and function required for the final part, but also each material has different parameters for molding that must be taken into account. Common polymers like epoxy and phenolic are examples of thermosetting plastics whereas nylon, polyethylene, and polystyrene are thermoplastic injection molding.
