Until recently, the idea of a machine tool operating in zero gravity seemed like pure science fiction. Today, however, it is becoming reality—advanced machining is making its way into space. In microgravity conditions, the first devices are being tested to manufacture mechanical parts directly in orbit. This is a technological breakthrough that could change the way crewed missions are conducted and, in the future, enable the construction of space infrastructure on distant planets. Why machining in space? Transporting every gram of cargo into orbit costs thousands of dollars. In emergency…

Modern PVC Windows – Technology and Innovation in Window Joinery
PVC (polyvinyl chloride) windows have revolutionized the window joinery industry in recent decades. Thanks to advanced production technologies, innovative technical solutions, and constantly developed material properties, contemporary plastic windows offer exceptional performance parameters while maintaining an affordable price. Window Profile Construction Modern PVC window profiles are characterized by multi-chamber construction, which significantly affects their thermal insulation properties. Leading manufacturers offer 5-, 6-, and even 8-chamber systems. Chambers filled with air or noble gas create an effective thermal barrier, while additional steel reinforcements ensure adequate structural rigidity. A key element is…
