Davis-Standard Corp. of Pawcatuck, Conn., exhibited a computer-integrated Killion/ Versa bump-tube extrusion system.

Normally involving two computers, the system allows recipe-downloading of parameters for the whole bump-tube profile from Davis-Standard's Epic 3 process controller to the Killion/Versa puller cutter, said Charles Sparacino, systems sales engineer in Commack, N.Y., for the firm's pipe, profile and tubing group.

The first system has operated in a New Jersey facility since May, and a second is being installed in California. The total system extrudes tubing of variable diameters and lengths and costs $200,000-$250,000, depending on control functions.
