M4E #60: How badminton shuttlecocks are made
Today, it’s time for a new how it is made video. Maybe at some point in your life you have seen a badminton match. You may even have played a match or two of this sport. I myself play several times with my wife, or I should say that I try to, as she’s the good one. One of the special things in this sport is the shuttlecock, and we are going to find in this video from BWF TV how Yonex makes them for competitions.

The use of feathers in shuttlecocks has raised concerns about animal welfare and the environmental impact. Some manufacturers are exploring sustainable alternatives to feathers and developing eco-friendly shuttlecocks that behave as well as those using goose feathers. Synthetic shuttlecocks, often made from nylon or plastic, are more durable and affordable than feather shuttlecocks. However, tThey are often used for casual play and in situations where feather shuttlecocks might not be practical, such as outdoor play.
Shuttlecock speed is tested and classified in controlled temperature conditions, typically in a range of 22-23 degrees Celsius (71-73 degrees Fahrenheit). The shuttlecock is launched at a certain velocity, and the distance it travels within a specific time frame is measured. This test is used to determine the shuttlecock's speed classification.
Temperature affects shuttlecocks in badminton by altering their speed, flight trajectory, and durability. Shuttlecocks are often classified into different speed grades (e.g., 77, 78, 79) to help players select the appropriate shuttlecock for specific temperature conditions. In cold weather, shuttlecocks with lower speed grades are preferred due to denser air, resulting in slower flight, while in warm weather, higher speed grades are chosen for their faster flight in less dense air. The guy near the end of the video testing the fligh of shuttlecocks is performing this grading. You can check here a speed chart.
