Abstract
A modular plastic conveyor belt hingedly interconnected by hinge pins made of a highly oriented polymer material. The hinge pins are preferably extruded from a material including a highly oriented polymer, such as polyethylene, polypropylene, or nylon. Alternative materials include highly oriented acetal or polyurethane. Plastic hinge pins made with these polymers having their long molecules oriented along the axis of the shaft of the hinge pin are exceptionally strong and resistant to deformation.
