How It's Made

Programme Overview

Anatomical Models/Jukeboxes/Tortilla Chips/Spark Plugs is a Quest documentary episode that delves into the intricate production processes behind three seemingly unrelated items – jukeboxes, tortilla chips and spark plugs – and charts how cutting‑edge technology has reshaped their manufacture. Presented in a clear, factual style, the programme offers UK viewers a rare behind‑the‑scenes look at modern factories, from traditional hand‑crafted methods to fully automated, data‑driven lines.

What to Expect

The episode begins with a step‑by‑step exploration of jukebox manufacturing, tracing the evolution from mechanical coin‑operated units to today’s digitally controlled, touchscreen‑enabled machines. Viewers will see how CNC machining, laser engraving and robotic assembly have replaced manual wiring, delivering higher precision and faster production cycles.

Next, the focus shifts to the food sector, revealing the journey of tortilla chips from field to snack aisle. The programme highlights the nixtamalisation of corn, extrusion technology, high‑speed frying, and automated seasoning dispensers, illustrating how sensors and real‑time quality monitoring ensure consistency while reducing waste and energy consumption.

The final segment examines spark plug fabrication, showcasing metal forging, ceramic insulator moulding and laser‑driven electrode shaping. Advanced testing rigs, AI‑based defect detection and IoT‑linked performance analytics are shown to have dramatically improved reliability and lifespan, reflecting the automotive industry's push for efficiency and sustainability.
