Injection molding is a widely used molding process for thermoplastics. Some thermosets and elastomers are injection molded when equipment is modified and operating parameters allow for the cross-linking of materials.
It's possible to create complex, intricate shapes with injection molding. It requires designing and fabricating a mold whose cavity has the same geometry as the original part. It must also allow for part removal. Part sizes range from 50 grams (2 ounces) to 25 kilograms (55 pounds). Heavier items made using injection molding include automobile bumpers and refrigerator doors.
