Metal vs. plastic: specification of large outdoor enclosures
Large, outdoor enclosures are a necessary aspect of the general infrastructure of day-to-day life. Used to house vital control panels and electrical connections, these enclosures must be able to withstand all that is thrown at them to protect their contents; this includes extreme temperatures, rain, UV exposure and even vandalism attempts. Due to its inherent strength, steel has traditionally been the material of choice despite several shortcomings; but can glass-reinforced polyester (GRP) offer a robust alternative which offers protection where steel cannot?

Pneumatic cushioning: save costs with the right adjustment
Productivity, energy efficiency, and a long service life: these three requirements are at the top of the list for end users when it comes to pneumatic automation systems. And most of the time just the right adjustment is sufficient to meet these requirements precisely. With optimally adjusted pneumatic cushioning, machine manufacturers and system integrators can shorten cycle times by up to 40%, increasing productivity accordingly. At the same time, they often lower air consumption by more than 50% compared with cylinders with pre-adjusted cushioning.
