You may not know it, but the injection-molding process plays a key role in creating a multitude of products you use every day. Did you comb your hair or button up your clothes this morning? Or maybe you strapped your little one into a car seat or cracked open a bottle of water.

It all started more than 145 years ago in 1872, when brothers John and Isaiah Hyatt patented a device for heating and injecting celluloid into molds by means of a plunger.
