integrated barrels directly on an extruder line with our wear measurement service. The barrels only need to be clean and cooled down.” The company demonstrated its BMD camera
– which records inside barrels with high clarity, says the company.

Reiloy division. “If it is too small, frequent downtimes – due to high wear – will reduce your profit. However, oversized components require high investment.” If the raw materials to be processed are in the
middle range – between simple and very demand- ing – then R131 can be the right choice, it says – of- fering three times the wear protection of the standard R121 alloy without having to invest in a much more expensive nickel-based alloy. Three general conditions indicate that R131 can help achieve the best cost-benefit ratio, it says. The first is when planning to process very
different materials on a line, such as technical plastics, high-temperature raw materials or material with a high filler content – which requires a high level of wear- and corrosion-protection. Here, standard protection is often not sufficient. The second is noticing wear when using a
standard alloy (such as R121). The required service intervals often cause downtime, the loss of produc- tion capacity lower profit. While investing in a nickel-based alloy is out of proportion, R131 can help to increase uptime in a profitable way. The third is using an oversized alloy – such as a
nickel-based alloy that is effectively ‘over engi- neered’. R131 can allow customers to save money without sacrificing performance or uptime. “Switching from nickel to iron can also have a positive effect on screw wear, allowing you to use standard screws,” said Nuber.
Barrel protection CA Picard exhibited a number of its technologies at the recent Plastic Japan exhibition in Tokyo. Its barrel measurement device (BMD) claims to boost operating efficiency by providing accurate information on barrel wear – and providing analytical reports. “Those that want to remain permanently produc- tive must detect wear and tear at an early stage,” said the company. “We can inspect the condition of

Austrian coating facility US-based Extreme Coatings has opened a 15,000 sq ft facility in Austria that will offer its wear-resist- ant coating applications to customers. The manufacturing facility will produce high- performance coatings for feedscrews in both extrusion and injection moulding applications – to meet growing demand from European customers. Extreme Coatings says that its thermal spray technology applies wear- and corrosion-resistant CarbideX protective coatings – made of tungsten or chromium carbide – to most new or repaired feedscrews. The process provides a crack- and porosity-free coating within thicknesses of 0.004- 0.017in per side and hardness values over 60HRc. CarbideX Proline formulations deliver as-new performance and two to three times longer equipment life, it claims.
It has established a licensing agreement with local engineering services provider FS Maschinen- bau to operate the facility. It has also transferred technology and know-how to FS Maschinenbau – with new equipment being installed at the plant. The increased capacity will shorten lead times, cut shipping costs and establish local supply for the company’s customer base in Europe, it says. “We’ve expanded our global footprint so we can
break the logistical logjam that exists today and ensure stable supply to all key European regions,” said Scott Caplan, executive vice president at Extreme Coatings. In addition, screw specialist Xaloy will establish a new R&D centre in Ohio, USA to expand produc- tion capacity and create new technologies. “We are a key enabler of advances in polymer
processing,” said Cheryl Sayer, chief technology officer at Xaloy. “The innovation centre will set a new standard in the industry.” Accomplishments in its 90-plus year history include the first tungsten carbide barrel to withstand extreme wear and corrosive environments, it says.
