Is there differences in plastic quality? Why does cheap plastic like plastic forks or cheap headphones crack and break after some use. Yet plastic like in the Nintendo switch and or Nokia phones soo god damn durable. Swear some plastic is strong as steal while other plastics are weak as paper.

There’s just different types of plastic lol.
There are different densities and compound configurations. Also, there is a difference between a plastic compound and polymers.
If the object is big enough to have a stamp, you will find an indicator of the type of material it is made from. For example, most 5 gallon buckets are HDPE 2 (High Density Poly Ethylene), and some deli containers are PP5 (Polypropylene). Each has a different melting point, and other tolerances.
Plastics are just different type of polymers. Some are stronger than others. Hence some are cheaper than others 😉😉
