Ford MuCell plastic

Just like every other automaker, Ford is looking into making its cars lighter, and thus more eco-friendly. Thanks to a bubble-infused plastic introduced at the Massachussetts Institute of Technology [MIT] called MuCell, Ford says it can step further toward its goal of lightening all its cars by anywhere from 200 to 750 pounds.

MuCell is made by pumping tiny bubbles of nitrogen or carbon into standard injection-molded plastics. Though the bubbly plastic is slightly weaker than the standard stuff, Ford says the difference will be negligible, since its plastic parts are engineered to be 50 to 100 percent stronger than they should ever need to be.

Though the idea is still in development, Ford says it wants to be running MuCell plastics in all its cars by 2020. Though the technology has been around since 1995, it hasn't made sense for automakers to start buying in until now. With a new focus on green technology in the automotive industry, the move suddenly makes a lot of sense, and Ford will start using the plastic in items like engine covers beginning in the next few years.

FORD'S CHOCOLATE-INSPIRED WEIGHT SAVING TECHNOLOGY

* Honeycomb structure MuCell plastic parts save 20 per cent weight, improving fuel economy and emissions, without compromising durability
* Injection of gas during moulding creates a cross-section resembling an Aero chocolate bar on a microscopic level, with the bubbles meaning less plastic is used
* Parts require less energy and time to manufacture, reducing emissions and cost

BRENTWOOD, Essex, 4 April 2011 – In their never-ending quest to reduce weight and therefore emissions and fuel use, Ford's engineers have taken inspiration from the Aero chocolate bar to produce lighter plastic parts by injecting gas bubbles during manufacturing.

There are many areas where weight can be saved by changing the type or grade of metal used to a stronger, lighter material to trim kilos from the kerb weight. Plastic parts are an area where it is traditionally difficult to save weight without sacrificing strength, durability or function, but Ford has found a solution. MuCell technology introduces gas bubbles into the plastic as it is moulded, leaving a microscopic honeycomb structure. These tiny spaces save weight by reducing the amount of plastic used, without compromising the integrity of the part.

Weight plays a key role in vehicle emissions and reducing the overall mass of the vehicle results in improvements to fuel economy and carbon emissions. Vehicle weights have increased in the last 30 years to allow for much greater levels of equipment and radically improved safety attributes. Ford has targeted reducing weight while still providing class leading levels of equipment and 5-star Euro NCAP safety ratings.

MuCell brings a host of other benefits with lower pressures used to mould the plastic and up to 33 per cent more parts per hour than a conventional process. This increase in speed and efficiency reduces energy consumption, manufacturing emissions and cost for parts produced using the innovative technique.

Ford's MuCell technology expert Carsten Starke is excited by the potential of the new process: "The first time I saw this plastic under the microscope I thought to myself it looks like an Aero chocolate bar!The bubbles in the chocolate change the taste, but in our plastics they save weight and making cars lighter reduces emissions and fuel consumption significantly," he said.

"We are saving weight in many ways, not just by using this new plastic, because lighter cars handle better, accelerate faster and stop more quickly. For the customer it is win-win, the plastic is 20 per cent lighter without increasing cost or reducing strength and it will help make their Ford better in almost every aspect."

The MuCell technology will see its first application in engine covers on vehicles such as Focus, C-MAX and Grand C-MAX, S-MAX, Mondeo and Galaxy in the next few years. Ford has committed to a minimum of 100kg weight reduction from even its smallest cars and 300kg from larger cars by 2020 as part of environmental initiatives. Weight saving, including deploying MuCell technology, is also achieved from other materials such as high-strength Boron steels which are used extensively in Ford models.

These new materials join innovations such as the EcoBoost petrol engines, which allow the use of more efficient, lower capacity engines even in larger vehicles without sacrificing performance. A range of other measures including automatic stop-start engines, aerodynamic grille shutters and low rolling resistance tyres make Ford's ECOnetic models amongst the most efficient on sale.
