‌The main differences between a fully enclosed cold former and a semi-enclosed cold former are their construction, the environment in which they are used and their cost.

Structure difference:

Totally enclosed cold heading machine encloses the transmission part, aiming at preventing dust and impurities from falling inside the die set, thus protecting the precision and service life. This design effectively isolates external contaminants, ensuring stable machine operation and high product quality.
Semi-closed cold headers, on the other hand, have a slit on both sides, mainly for the slide, through which the drive parts inside can be seen. This design allows a certain degree of observation and adjustment, while maintaining a certain degree of protection, suitable for less dusty working environment.
Difference in use environment:

Totally enclosed cold heading machine is suitable for the harsh environment with more dust, foreign matter and impurity, or special environment such as clean workshop, because it can effectively isolate the external impurity and ensure the cleanliness of the machine and products.
Semi-closed cold heading machine is mainly suitable for the working environment with less dust, because it allows a certain degree of observation and adjustment, and at the same time maintains a better air permeability, suitable for use in a clean environment.
Cost difference:

Totally enclosed cold formers are relatively expensive, mainly due to their special enclosed design and higher manufacturing difficulty. Totally enclosed cold formers are more complex to manufacture and assemble, thus increasing the cost.
Semi-enclosed cold headers, on the other hand, because of their relatively simple structure and manufacturing, have relatively lower costs and are more suitable for users with limited budgets.
To summarize, the choice between fully enclosed and semi-enclosed cold formers should be based on the specific needs of the work environment, budgetary considerations, and product quality expectations.
