How do manufacturers test the trash can’s resistance to extreme temperatures?

Manufacturers rigorously test trash cans for extreme temperature resistance to ensure durability and functionality in diverse environments. The process typically involves exposing the trash can to both high and low temperatures in controlled thermal chambers. For high-temperature testing, the trash can is subjected to heat levels simulating prolonged sun exposure or hot climates, often reaching up to 60°C (140°F) or higher. Conversely, low-temperature testing involves freezing conditions, sometimes as low as -20°C (-4°F), to assess brittleness or cracking risks.

Additionally, cyclic testing is performed, where the trash can undergoes repeated temperature fluctuations to mimic real-world conditions. This helps evaluate material expansion, contraction, and long-term structural integrity. Manufacturers also inspect for warping, discoloration, or weakened seams after testing. Advanced methods may include impact tests at extreme temperatures to ensure the trash can remains functional under stress.

Materials like high-density polyethylene (HDPE) or stainless steel are often preferred for their thermal stability. By combining these tests, manufacturers guarantee that trash cans withstand extreme temperatures without compromising performance or safety.
