With the rise of electric vehicles, new technologies, and tougher fuel standards, the automotive industry is booming these days, and so is the plastics industry. With manufacturers looking to make lighter, less expensive components, while also installing new electronics and their housings, there have been numerous innovations involving plastic automotive parts and designs in 2017, and there are even more on the horizon.
Plastic automotive components can be susceptible to rework, rejection and budget-breaking increases in total cost of production if the parts used contain molding defects. Often these defects evidence themselves during end product review — when it could be too late for a remedy.
Federal Corporate Average Fuel Economy (CAFE) Standards coupled with heightened consumer sensitivities to the environmental impact of using fossil fuels are tightening fuel consumption requirements for the auto industry.
The automotive industry is experiencing rapid advancements, some of which have been brought about by federal regulations and others as a result of manufacturers leveraging opportunities presented by new materials and technologies.
Using injection-molding for complex, critical-use plastic automotive components is a practical solution for manufacturers to keep pace with evolving governmental standards.
The overall safety and performance of a vehicle is dependent, in part, on the plastic components used throughout the vehicle. Many people think that when it comes to cars, plastic parts are features like the dashboard, seats and floor mats. But thermoplastic polymers are used in much more critical places throughout a vehicle, many of them under the hood in the car’s powertrain and fuel systems.
In fact, up to 13 different polymers may be used in a single car model, with polypropylene, polyurethane and polyvinyl chloride (PVC) making up 66% of the polymers used in a car.
Since 1975, the automotive industry has been under governmental mandate to improve the average fuel economy of cars and light trucks manufactured in the United States. The Corporate Average Fuel Economy (CAFE) standards, born out of the Arab Oil Embargo of the mid-70s, are still in effect today with recently added emphasis placed on further improving fuel economy, reducing greenhouse gases and saving people money at the gas pump.
In a recent blog, we explored how injection molders can reduce automotive component costs and risks if they’re involved early in the design process.
But, how about the impact of the plastic automotive components themselves? What benefits can manufacturers realize in using them?
With nearly a quarter million manufacturing jobs reshored in the U.S. since 2010, it appears many automotive manufacturers are finding upfront offshore savings come with a heavy cost in parts shortages, production line shutdowns, product defects and transportation delays.
