Understanding the full lifecycle of a molded part is essential for today’s mold builders. That’s why we’re having our 2025 summer school series cover Pellet to Part — a series that explores each step of the plastic injection molding process, from raw resin to finished product. Whether you're a seasoned pro or new to the shop floor, this series will give you a comprehensive look at the materials, machines, and methods that bring molded components to life. Think of it as your go-to guide for bridging the gap between mold design, manufacturing, and the molding process itself.
