Corrugator molds chain of Coex barrier parts.


Vacuum corrugators developed for automotive fuel lines by Corelco Cie, Manziat, France, offer new software for such precise speed control that processors can use them to mold mold, name for certain multicellular organisms of the various classes of the kingdom Fungi, characteristically having bodies composed of a cottony mycelium. The colors of molds are caused by the spores, which are borne on the mycelium.  a multilayer tube into a continuous chain of hollow barrier parts. The parts need not be identical, but can vary widely in diameter. This capability was developed 18 months ago for a French molder mold·er

, which made up to 65 small parts at a time. Each part had a diameter change requiring two speed changes, for 130 speed changes per rotation of the molds. Careful speed control maintained wall thickness while increasing or decreasing part diameter.

Speed control reportedly is so precise that it allows forming and cutting parts with closed ends. In January Corelco delivered a corrugator cor·ru·ga·tor

Speed and position control also simplifies mold changes by advancing the corrugator and stopping only at blocks that need to be replaced for the next product. Typically only a dozen or so blocks are changed out of a total of 37 to 65 pairs. It takes about 15 sec to replace a block since cooling lines pass behind the blocks, not through them.
