Ep 15. Plastic Injection Moulds, Automotive Oil Filters, Filing Cabinets, Blown Glass

"How It's Made" season 2 episode 15 is a fascinating look into the manufacturing process of plastic injection moulds, automotive oil filters, filing cabinets, and blown glass. This episode explores the intricate methods and techniques used in the creation of these everyday objects that we take for granted.

First up, viewers will get an inside look at the creation of plastic injection moulds. These moulds are used to produce a variety of plastic products, from food containers to automobile parts. The episode takes us step-by-step through the mould design process, including the use of computer-aided design tools and 3D printing technology. We learn how the moulds are made from high-quality steel and how they are precision-machined to ensure that they can produce thousands of identical plastic parts with ease.

Next, we move on to the production of automotive oil filters. Oil filters are a vital component of any vehicle, helping to keep the engine clean and running smoothly. In this episode, viewers will see how layers of paper, synthetic fibers, and metal mesh are combined to create a filter that can trap dirt and contaminants without restricting oil flow. We also learn about the testing and quality control measures that ensure every filter meets industry standards.

After that, we take a look at the manufacturing of filing cabinets. Filing cabinets have been a staple of offices and homes for decades, but few people know how they are made. In this episode, we see how sheet metal is stamped and formed into the various parts that make up a filing cabinet. We learn about the different types of locks and mechanisms used to keep files secure, as well as the finishing techniques that give each cabinet its unique look.

Finally, the episode concludes with a behind-the-scenes look at blown glass production. From delicate drinking glasses to intricate sculptures, blown glass is a versatile material that has been used in art and design for centuries. In this segment, we see how molten glass is manipulated with specialized tools and blown into various shapes and forms. We learn how color is added to the glass, whether through the use of pigments or the incorporation of other materials. We also get a glimpse of the impressive skill and precision required to create complex pieces of blown glass.

Overall, "How It's Made" season 2 episode 15 is a fascinating and educational look at the manufacturing processes behind four different types of everyday objects. Whether you're interested in engineering, design, or just like to learn new things, this episode is sure to capture your attention and broaden your horizons.
