How It's Made

The programme outlines the manufacturing processes used to produce decorative mouldings, commercial pulleys and hoses, detailing each step from material selection to final finishing. It also offers insight into how these production methods have evolved over the years, highlighting key technological and design changes.

The episode titled Decorative Mouldings/Commercial Pulleys/Hoses forms part of a programme that looks closely at industrial manufacturing. It presents a concise, episode‑length overview of three distinct product lines – ornamental mouldings, heavy‑duty pulleys used in commercial settings, and a range of flexible hoses. In the first part of the episode the step‑by‑step methods used to produce each item are shown. For decorative mouldings the process begins with selecting a suitable material, shaping it on specialised moulds, then finishing and coating it to achieve the desired aesthetic. The segment on commercial pulleys follows a similar pattern, outlining the casting or forging of the wheel, the machining of the groove, and the installation of bearings. The hose portion demonstrates how raw polymer compounds are extruded, reinforced, and then cured to create a product that can withstand pressure and environmental stress. The programme then turns to a historical perspective, tracing how the techniques for making these components have changed over time. It highlights the shift from manual, labour‑intensive methods to more automated, precision‑driven processes, noting the introduction of new alloys, synthetic materials and computer‑controlled equipment. Overall, the episode provides a clear picture of both the current manufacturing workflow and the gradual technological advances that have shaped the production of decorative mouldings, commercial pulleys and hoses.
