Ep 2. Plastic Molds and Oil Filters

In season 4 episode 2 of How It's Made, viewers are given an inside look into the production processes involved in crafting essential items like plastic molds and oil filters. This episode delves deep into the world of industrial manufacturing, showcasing the intricate steps required to create these necessary components.

The episode begins with a segment on plastic molds, demonstrating how they are made using a number of different methods, including injection molding. Viewers are given a close-up look at the machinery involved in this process, which comprises of a clamping unit and an injection unit, and how they work together to produce precise and detailed molds. The segment also explains how different types of plastic materials are used in molding to create a variety of products, such as bottles, toys, and even car parts.

The show then transitions to a segment on oil filters. The manufacturing process begins with a steel housing that is punched and formed using specialized equipment. The segment then dives into the intricate steps involved in the creation of the oil filter's internal components, such as the filter media, gasket, and anti-drain back valve. These components are assembled in a specific order to create a functional filter that can effectively trap and remove unwanted particles from the engine oil.

As the episode progresses, viewers are given a detailed look at the different materials used in the production of both plastic molds and oil filters. This includes an explanation of how plastics are derived from petroleum, as well as the various types of filter media (such as cellulose or synthetic fibers) used in oil filters. In addition to detailing the raw materials involved, the show also explores the environmental impact of these manufacturing processes, highlighting the efforts made by companies to reduce waste and emissions.

Throughout the episode, viewers are treated to a variety of fascinating visuals that bring the production processes to life. From close-up shots of molds being injected with hot plastic, to machines cutting and shaping steel for oil filter housings, the attention to detail is impressive. In addition to the manufacturing itself, the episode also discusses the quality control measures used to ensure that each product is up to industry standards.

Overall, the fourth season, second episode of How It's Made provides a captivating look into the world of industrial manufacturing. From the creation of plastic molds to the assembly of oil filters, viewers are given a behind-the-scenes glimpse into the meticulous processes required to create these essential components. Whether you're interested in the science behind manufacturing or simply curious about how everyday products are made, this episode offers something for everyone.
