Ep 12. Olive Oil, Lift Trucks, Seamless Rolled Rings and Ski Boots

In season 7 episode 12 of How It's Made, viewers are taken behind the scenes to discover the intricate processes involved in the manufacturing of a variety of products. The episode explores the manufacturing of four different items: olive oil, lift trucks, seamless rolled rings, and ski boots.

The episode starts with the process of making olive oil. The production begins with the harvesting of the olives, which are then washed and crushed. The resulting paste is then mixed and pressed to separate the oil from the remaining pulp and water. The oil is then filtered, and bottled before it is ready for consumption. The show explains some of the different grades of olive oil, including extra virgin, virgin, and pure olive oil.

The second segment takes viewers to a manufacturing plant where lift trucks are being made. The process starts with the construction of the lift truck frame. The frame is then painted and the various components, such as the wheels and the hydraulic system, are assembled onto the frame. The lift truck is then put to the test in a specialized testing area to ensure it meets safety and performance standards.

The next item on the show is seamless rolled rings. These are large metal rings that are used in industrial applications, such as turbine engines, to withstand high levels of stress and pressure. The manufacturing process begins with a circular piece of metal that is heated and formed into a donut shape. The donut is then rolled and squeezed between two rollers to create a seamless ring. The ring is then heat treated and tested for strength before it is sent to the customer.

Finally, the episode looks at the production of ski boots. It starts with the design process, where the shape and materials of the boot are carefully considered. The outer shell of the boot is then molded from a special kind of plastic, which is selected for its durability and strength. The inner liner of the boot is made from a kind of foam that is specially selected for comfort and warmth. The boot is then assembled, tested, and customized for each individual skier to ensure a perfect fit.

Throughout the episode, viewers get an insight into the complex manufacturing processes involved in these four very different products. From the harvesting of olives to the assembly of lift trucks, and from the forging of seamless rolled rings to the molding of ski boots, every step of the process is explained in detail. Viewers are given a glimpse into the world of manufacturing and see firsthand the skills, knowledge, and precision required to create these remarkable products.
