This is what is said to be the largestvibration-welded plastic intake manifold inNorth America: its for the Ford 5.4-literSOHC Triton V8 engine (used for F-Series,Econoline, Expedition, and Excursionapplications). The manifold was developed
by a team consisting of representativesfrom Ford, molder Montaplast North
America, and plastics-supplier DuPont Automotive. How big? 16.3-kg of Zytelwelding-enhanced PA 66 nylon resin areused. The welding enhancement is
important in that there is a 4-meter long vibration weld that joins the bottom and tophalves of the manifold.

That is, he says that in 1998, 100% of the air intakemanifolds produced in the Americas were made with nylon66. This is the material that started it all. So the equipmentnecessary to make manifolds with this material mainlylost-core molding is in place. There is installed capacity.But in the not-too-distant future, as there are manifold
redesigns, there is, that data describe, a change to nylon 6which, Ferrighetto explains, provides an overall costadvantage in that there is a lower capital equipment cost(the approach here is to make separate parts that are
joined through vibration welding ), a reduced cycle time,
and a slightly lower material cost. The numbers indicate thatby 2004, there may be a 60/40 split between 66 and 6.
