Instead, they are directly piled up in the waste bin of the factory area by traditional methods without any crushing or compression treatment. This traditional metal scrap treatment method has the following defects: 1. It cannot improve the on-site environment, and cannot give customers or auditors a good impression. 2. The cutting oil in the cutting process cannot be quickly recovered from the metal scrap. The metal scrap can only be stored for a period of time before the cutting oil can be slowly dripped and collected by its own gravity, so more spare cutting must be prepared Oil costs more. 3. The metal scrap has not been crushed and compressed, so it takes up a lot of storage space and cannot store more metal scrap. 4. It is particularly important that metal scraps (such as defective metal products) that have not been crushed or compressed may reveal intellectual property rights in terms of trade secrets, product design, or product shape and structure.
