Above: Reiloy’s extensive range of extruder screws includes special designs for degassing
according to the material to be processed,” says Ralf Pampus, Managing Director of the company. “Reiloy’s core competence is wear resistance for
screws and barrels through our sophisticated alloys, which are established in markets world- wide,” Pampus says. “One of our latest develop- ments is a state-of-the-art laser welding manufac- turing process for high performance alloys. For this purpose, we have commissioned a completely new facility that uses high-precision laser welding to reduce the thermal impact on the base material and optimise the armouring structure of the welded alloy powder. This eliminates changes to the original geometry of the component and increases the wear-protection.” Reiloy says it continues to develop its wear
resistance technologies. “To this end we operate our own materials laboratory with associated hard material production at our headquarters in Troisdorf, Germany,” says Pampus. “This is a unique selling point in the market. It allows us to offer our alloys with 100% consistent quality and to respond individually to customer requirements in the design of wear resistance with regard to abrasion, corrosion and adhesion. In the last two years we have invested significantly in new test equipment, such as a new scanning electron microscope and a testing device

for determining the wear of screws and barrels.” The latest product from Reiloy for screws is a laser welded RC3 alloy, while for barrels the company has introduced the R131, R239 and R241 alloys. “In addition to the alloys, Reiloy has also developed its own production equipment, such as a new centrifugal casting line for bi-metal cylin- ders,” Pampus says. “By offering greater added value in hard material development and produc- tion, as well as plant engineering, we can provide good quality for the customer that results in higher extrusion performance and longer service life.” Private investment firm Altair Investments recently closed its purchase of Nordson Corporation’s Xaloy screws and barrels product line, formerly part of the Nordson Polymer Processing Systems (PPS) division. “Xaloy represents a truly global business with a market-leading brand name and a long-standing reputation for high-quality products and innovative engineering,” according to Andrew Brickman, a part- ner at Altair. “We intend to build upon the many strategic investments made by Nordson that provide a tremendous platform for future growth.” Last month, Xaloy announced it was to invest $1.75m to reopen its formerly shuttered plant at Pulaski in Virginia in the US and relocate its bimetal- lic barrel manufacturing from Austintown in Ohio. “With the increase in demand, we were reaching capacity with our twin-barrel line in Austintown,” says Xaloy CEO Kamal K Tiwari.
