Tough, Durable Material Breathes New Life into Reaction Injection Molding

Reaction injection molding (RIM) is a process that mixes two precisely metered chemicals under pressure, yielding a low-viscosity liquid that is then injected into a mold to form a thermoset polymer part. The low-pressure, low-temperature process is known for its design flexibility, enabling molders to make complex parts with varying wall thicknesses and to encapsulate structural components for electronics, batteries, or antennas.
