generally speaking, enterprises will determine whether there are professional restrictions on the recruitment of craft positions according to the requirements and needs of the positions. The specific situation may vary from enterprise to enterprise, and the following are some common situations:

1. There are professional restrictions: some enterprises have professional requirements for craft positions, and the candidates are expected to have relevant professional background knowledge and skills. For example, enterprises may be more inclined to recruit talents in related majors, such as mechanical engineering, process manufacturing and other majors, for jobs with high requirements for specific technologies.

2. No professional restrictions: Some enterprises may pay more attention to the actual work experience and skills of candidates, and have no clear requirements for professional background. For example, for some craft positions, actual work skills and experience may be more important than professional knowledge, and enterprises may be more willing to recruit candidates with relevant experience.

to sum up, whether there are professional restrictions mainly depends on the specific recruitment requirements and job requirements of the enterprise. It is suggested that you can check the recruitment information or contact the recruiter directly to get more accurate information.
