Automotive Plastic Components Injection Molding

Automotive Plastic Components Today

High automotive performance demands parts that handle it all. Plastics perform from the engine to the chassis; throughout the interior to the exterior. Today’s automotive plastics make up approximately 50% of the volume of a new light vehicle but less than 10% of its weight.

Safety
Safety advances in today’s materials save countless lives. Air bags, windshields, sunroofs plus energy absorbing innovations reduce vehicle fatalities. Plastic front-end modules, modular seats and energy-absorbing bumpers help save lives every year.

Plastic composite structures can help lightweight vehicles while preserving safety features. When a vehicle crashes, engineers want the structure to crush in a predictable way. Automotive materials should absorb, not transfer, the “impact energy” to humans. The industry calls this a “controlled crush.”

Fiber-reinforced polymer composites absorb four times the crush energy of steel. The B-pillar is the support post that connects a vehicle’s roof to its body. It is at the rear of the front door and provides the major source of resistance to intrusion during a collision.

The National Highway Traffic Safety Administration recently funded a study on B-pillars. The study looked specifically at a composite intensive carbon fiber thermoplastic B-pillar design. The goal was to determine the design’s weight savings and vehicle crash safety as compared to a metallic baseline. The B-pillar showed 60 percent weight savings, and satisfied side-impact crash requirements. Computational tools modeled the dynamic impact and crush response B-pillars.

Plastics are helping save lives during pedestrian impacts too. Polycarbonate-blend bumpers help protect passengers in collisions. Plastics also enable faster deployment for greater pedestrian protection in Ford vehicles. A flexible pedestrian-protection crash direct-mounted sensor bracket injection molded in plastic.
