Single screw extrusion uses one screw within a cylindrical barrel to continuously push plastic through a constant profile die. Production rate is typically measured in mass per hour (lb/hour or kg/hour) and is controlled by the screw speed of the machine.
Most extruder products are produced using single screw extrusion. Parts such as window frames, house siding, and weather stripping, which have a constant profile, are generally produced by means of single screw extrusion. Due to such factors as the melt swelling as it exits the die, the die design for an extruder is critical. Great complexity is sometimes needed with an extrusion die in order to gain the correct profile.
The two largest industries for extrusion are pipe and tubing extrusion and film and sheet extrusion. There are many other industries that use extrusion to create their products though. Fiber extrusion, for clothing, coating extrusion, and blown film extrusion are just a few of the others.

I attended the IFBA regional meeting Saturday. Â Afterwards they hosted an apparatus shoot for the entire Racine FD. What a great opportunity to see and photograph their apparatus fleet. Got a good look at the Racine fire museum which is worth the trip all by itself. Also got to meet and renew aquaintance with many members of the fire buff club, all in all a great day. A huge thanks to the Fire Bell Club and the Racine FD officers and members for showing us a great time!!
