Lena: You know what fascinates me, Miles? When a company manages to stay relevant for over 70 years in an industry most people never think about. Like Leister—this Swiss company that's basically the wizard behind the curtain of plastic welding.
Miles: Oh, Leister is such an interesting case! They've been quietly dominating the plastic welding and industrial heating world since 1949. Imagine being the company that makes the tools that literally hold our infrastructure together—from tunnel linings to shrimp farms in Indonesia.
Lena: Wait, shrimp farms? That's unexpected!
Miles: Right? There's this fascinating story about how their TWINNY S welding machine creates these precise, watertight seams for massive shrimp breeding tanks in remote Indonesian regions.
