Change pipe diameters on the fly. (Extrusion).A novel pipe extrusion system allows product dimensions to be changed in minutes without stopping the extruder or changing dies. This lets processors meet small orders faster while making less scrap and storing less inventory. Krauss-Maffei Krauss-Maffei is an injection molding machine manufacturer based in Germany. The company produces various types of equipment as well as railroad locomotives, tanks, self-propelled artillery and other armoured vehicles. in Germany Germany (jûr`mənē), Ger.

The patented system, called QuickSwitch, uses an adjustable pin in the die head to change wall thickness. Pipe diameter is changed by adjusting haul-off speed and the diameter of the smooth-walled calibrator calibrator an instrument for dilating a tubular structure or for determining the caliber of such a structure. by means of a "calibrating basket" with movable sickle-shaped segments. The vacuum tank's end seal, guide rolls, and haul-off are also adjustable. Changeover (programming) changeover - The time when a new system has been tested successfully and replaces the old system. takes a few minutes and creates a piece of scrap less than 1.5 meters long before producing on-spec pipe of the new size, Krauss-Maffei claims. QuickSwitch comes in three sizes: KM-QS 32-63 for pipe OD of 32 to 63 mm, KM-QS 75160 for OD of 75 to 160 mm, and KM-QS 160-250 for 160 to 250 mm OD. It's retrofittable to existing pipe lines.
