Engineering resins are one of two types of plastics commonly used in the injection molding process. Commodity resins (the other common type) are inexpensive and typically used in consumer products like toys, packaging, and food containers. Engineering resins are ideal for use in industrial applications because they are strong and highly resistant to temperature, corrosion, and wear. Engineering resins also have special thermal and mechanical properties that make them useful in replacing wood and metal to save on costs and/or weight.
