Thermoplastic Fire Helmets, Basketry Sculptures, Coffee Roasters

Still from How It's Made S29E04

Summary

Heat-resistant thermoplastic is moulded into protective helmet shells before liners, shields, straps and identifying trim are installed. Flexible natural materials are woven over shaped supports to create large basketry sculptures, while steel drums, burners, fans and electronic controls are assembled into machines that roast coffee beans evenly.
