Ep 25. Architectural Moldings, Pulleys, Industrial Rubber Hose, Sheet Vinyl Flooring

How It's Made is a fascinating show that takes us on a journey through the manufacturing process of various everyday items. In season 2, episode 25, we get a glimpse into how architectural moldings, pulleys, industrial rubber hose, and sheet vinyl flooring are made.

The episode begins with a look at architectural moldings, which are used to add decorative touches to interior and exterior walls and ceilings. We learn that these moldings are made from a variety of materials, including wood, plaster, and even plastic. The process of making moldings involves using special machines and tools to shape and carve the materials into intricate designs. We see how wooden moldings are cut using a saw and then sanded and polished to create a smooth finish. We also learn about the different types of plaster moldings and how they are made by pouring plaster into molds and then letting it dry before it's painted or stained.

Next up, we explore the world of pulleys. Pulleys are used in a variety of applications, but they all have one thing in common: they help to lift heavy objects with minimal effort. We see how pulleys are made by taking a block of metal or plastic and drilling a hole through the center. A groove is then added to the perimeter of the pulley, which allows a belt or rope to loop around it. We also learn about the different types of pulleys, including fixed and movable pulleys, and how they work together to create mechanical advantage.

The third segment of the episode takes us into the world of industrial rubber hose. We learn that rubber hose is used in a variety of industrial applications, including pumping fluids and gases, and as a conduit for electrical wiring. We see how rubber hose is made by extruding a mixture of rubber and plastic through a machine that shapes it into the desired size and shape. Once the hose is formed, it's tested to ensure that it meets strict safety standards before it's sold and used in the field.

Finally, we dive into the world of sheet vinyl flooring. Vinyl flooring is a popular choice for homes and businesses because it's durable, easy to clean, and comes in a variety of colors and patterns. We see how sheet vinyl flooring is made by taking a mixture of vinyl chips and additives and feeding it into a machine that melts and shapes the material into thin sheets. The sheets are then printed with colorful designs and coated with a protective layer to prevent damage and wear.

Overall, season 2, episode 25 of How It's Made is a fascinating look into the world of manufacturing. We learn about the intricate processes and specialized machinery that go into making each of these products, and gain a newfound appreciation for the everyday items that make our lives easier and more beautiful.
