Federal-Mogul Holdings Corporation (FDML) announced that its Federal-Mogul Powertrain division has come up with an innovative clutch piston technology. This technology will help vehicles with automatic or dual-clutch transmissions gain more fuel-efficiency.
The new high-modulus Unipiston of Federal-Mogul Powertrains division provides transmission designers more flexibility, including increased clutch apply pressures, higher rotational clutch speeds, and larger diameter clutches. The company revealed that this flexibility enables transmissions with additional clutches to fit in a smaller space and provide enhanced fuel efficiency, reduced emissions and better vehicle performance.
Federal-Mogul has undertaken different strategies to develop the high-modulus (firmness) bonded piston. Also, the company has used environmental-friendly materials to develop the new elastomer material and has also implemented innovative procedures in the molding process.
The traditional bonded piston seal materials which are manufactured using traditional injection molding are limited in their modulus to around 10 megapascals (MPa). It becomes challenging while filling the mold cavity with traditional bonded piston, as the elastomer viscosity increases with modulus. However, new high-modulus Unipiston provides a modulus of over 20 MPa.
Federal-Mogul introduced the original bonded clutch pistons roughly 30 years ago. The company has taken various initiatives to make clutch pistons more compact and easier to assemble. High-modulus injection-molded Unipistons are now produced in high quantity.
Federal-Mogul is a global supplier of products and services to vehicle manufacturers and the aerospace, power generation and industrial markets. The company’s products help improve fuel efficiency, reduce emissions and enhance vehicle safety. Currently, the company holds a Zacks Rank #4 (Sell).
Better-ranked stocks worth considering in the sector are Visteon Corporation (VC), STRATTEC Security Corporation (STRT) and China Automotive Systems Inc. (CAAS). All the stocks sport a Zacks Rank #1 (Strong Buy).
