Don’t know what the purpose of your registration is? Also what is the nature of your processing location. Pavement? Factory building? Office building? Commercial and residential building? Shops and factories can be registered as processing plants or processing departments. It is recommended to register as "XX Laser Processing Department" and "XX Laser Processing Factory".
But one thing you must know is that when it comes to the nature of the processing, environmental protection and fire protection approvals must be obtained. In some places, it is difficult to get it or it costs a lot of money. And for the business scope, just write "laser engraving or laser processing". Don't include the word "marking". These two words are related to trademark law. It is not recommended if you only have one machine.
If the processing location is in an office or commercial building, it is recommended to register as "XX Laser Technology Co., Ltd." The registration process is relatively simple, and the business scope should be "laser engraving product research and development". But in the future, you will have to ask the finance department to do accounting every month.
