1. Unbalanced supply and demand in the market: If the supply of a brand-new machine in the market is too large and the demand is insufficient, the recycling price will be relatively low, because recyclers or second-hand markets can't sell these machines quickly, so they can only lower the price to attract consumers to buy them.

2. Fast technology update: With the continuous development of science and technology, new machines and equipment are constantly emerging, which also leads to the early elimination of the original machines. Therefore, in order to reduce the inventory pressure, recyclers will lower the recycling price in order to dispose of these machines faster.

3. Quality problems: Some brand-new machines will have quality problems, such as unstable performance and easy damage. In this case, the recycler will reduce the recycling price in order to prevent after-sales problems.
