from tubing, pipe or coiled and welded sheet metal. Rollformers can be used when fine detail and a good surface quality are required. Shrinkers are used when an accurate outer diameter is required. This process is exactly the opposite of expanding. Fontijne Grotnes offers expanders, shrinkers and rollformers to various industries: the aerospace industry for sizing rings in jet engines; the wind turbine industry for sizing seamless rolled rings for manufacturing of bearings and flanges; the automotive industry for gear rings; production lines for the inner housings of dishwashers; and other sizing technologies. Forged rings, both seamless rolled rings and flash butt welded rings, are commonly applied in for example the aerospace industry, particularly for jet engines. Fontijne Grotnes expanders are commonplace in the forging industry for sizing rings of all sizes and materials. The expanders of Fontijne Grotnes are used to calibrate the ring in order to minimise machining allowances and to eliminate local stresses. This greatly reduces the required amount of machining as the ring is closer to its final shape and more stable during post operations. Other benefits of the Fontijne Grotnes expander in the ring rolling process are: faster production process, considerable material savings, improvement of the mechanical properties of the material, achieving very tight inside diameter and ovality tolerances. The dies are easily interchangeable, which makes it possible to calibrate a wide range of rings, with both rectangular or profiled cross sections, using only one machine. For rings with a heavy cross

section of a very high yield point, water cooled dies are available for hot sizing. Website: www.fontijnegrotnes.com

directly replace vacuum cups with only minor tooling adjustments. Ideal for applications in the appliance, automotive, and office furniture industries, as well as numerous other material handling applications, the Transporter ® LP is next-generation sheet handling technology. It only requires a short, single burst of shop air to quickly release parts, and is available in three standard sizes with the strongest unit holding up to 162lb. Included in the LP line is the TPLP50. A 5", low profile transporter that is ideal for lifting thin sheets. It is also available with a destacking option that features a special magnetic circuit, designed to destack metal sheets as thin as 0.03" (22 gauge). The latest addition to the Transporter ® family is the Transporter ® MV (MagVac) end-of-arm tooling from IMI, combining

Industrial Magnetics Inc USA 1526 INDUSTRIAL Magnetics Inc patented family of Transporter ® magnetic end-of-arm tooling will be on full display at FABTECH. Transporters ® magnetically transfer metal blanks, stampings and parts in automated station-to-station, press-to-press transfer or robotic pick-and-place applications, among many others. Engineered with powerful rare earth magnets that positively hold the part during transfer – even during unexpected loss of shop air – the Transporter ® family greatly reduces chances for slipping and shifting of parts due to mill oil coatings, dust, dirt, rust or weld splatter. The Original Transporter ® is designed
