Ep 13. Traffic Signal Poles, Coffee Filters, and Chainsaw Mining Machines

In season 18 episode 13 of How It's Made, viewers are taken on a tour of three fascinating industries as they explore the making of traffic signal poles, coffee filters, and chainsaw mining machines.

The episode begins by showcasing how traffic signal poles are made. Viewers are transported inside a factory where workers bend and shape metal pipes into the classic pole shape. The poles are then galvanized to prevent rust and painted with reflective paint to increase visibility at night. The process is a delicate one where any imperfection could compromise the safety of drivers and pedestrians on the road.

Next, the episode dives into the world of coffee filters. Viewers get an up-close look at how this everyday item is made from start to finish. They enter a factory where they witness how raw materials are transformed into the final product. The coffee filter manufacturing process involves huge rolls of paper that are fed into large machines, stamped with the characteristic scalloped edges, and then cut into precise shapes. The filters are then packaged and shipped out to coffee lovers all around the world.

In the final segment of the show, viewers are taken into the world of chainsaw mining machines. These incredible machines are used to extract precious minerals from deep within the earth. The episode zeros in on how these machines are put together from start to finish. Viewers are treated to never before seen footage of the machines in action as they dig through layers of earth and rock, all while keeping the operator safe. The process of building these machines requires a highly skilled workforce and an incredible amount of innovation.

Throughout the episode, viewers are introduced to the men and women who make these products possible. From the factory workers who create the traffic poles to the engineers who design the chainsaw mining machines, every step of the manufacturing process is covered. The episode also highlights the complexity of each of these industries and the incredible attention to detail that is required to create quality products.

Overall, season 18 episode 13 of How It's Made is a fascinating exploration of these three industries. It provides a glimpse into the world of traffic safety, everyday conveniences, and the incredible technology of mining machines. Through the show's expert cinematography, viewers are able to witness first hand how these products are made and gain an appreciation for the skilled professionals who make it all possible.
