To answer your question, No, it would be totally unacceptable to manufacture Halaal meat in the same factory using the same equipment and staff as the non halal sausages.
In order for meat to be deemed Halaal, it is imperative to ensure:
1. Muslim Supervision (consultation with authentic Muslim Scholarly advice) from beginning to end. The rationale is quite simple. A devote Muslim would be aware of the essential Islamic Jurisprudence and other matters relating to Halaal. Also for a non Muslim providing Halaal meat would be of a purely monetary gain whilst for a Muslim it is a religious duty strictly adhering to legislative procedures as well as spirtual considerations providing Halaal meat for the Muslim Community.
2. No contamination takes place - Another very important factor to be considered is the high risk of contamination with Haraam (prohibited) meats which would mean there must be a strict demarcation from any prohibited (haraam or impure) substances.
Of course there are many more requirements but these are of the most prominent which serve the scope of this question.
