Knowledge Matrix | Science Facts on Instagram: "Workers use a powerful wire-stripping machine to extract pure copper from thick industrial cables. The process begins by feeding the insulated wire into rotating cutting gears that slice through the outer plastic or rubber coating. As the insulation is peeled away, the bright copper core is exposed and collected for reuse. This reclaimed copper is later melted down, refined, and repurposed for new electrical and industrial applications — reducing w

TrendTok Hub on Instagram: "The post shares a 14-second video of a CNC coiling machine transforming straight copper wire into a helical compression spring through precise winding, cutting, and end-forming, achieving over 640,000 views in two days. Its hypnotic, seamless visuals prompt AI suspicions in replies, yet the footage matches authentic spring production techniques documented in manufacturing guides, where wire is fed at speeds up to 1,000 coils per minute for efficiency. As a recurring v
