The short answer is a Linux box with network cards, routing between the 
segments.  Look up ip_forward, and try searching for the Linux Router 
Project. 

The longer answer depends on your goals:

   * Are you concerned about overall traffic swamping manufacturing
     critical traffic?
   * Are you worried about voltages on the manufacturing floor frying
     the office LAN?
   * Are you afraid that a rogue employee in the office programming the
     drilling machine to puncture every metal widget?
   * Is the same employee sniffing network traffic to capture CAD/CAM
     milling sequences to sell your customers?
   * Are your manufacturing employees surfing the web when they should
     be soldering, and you want to stop this practice?


Each one of these would indicate different solutions, taking into 
account your overall budget and knowledge.  For instance, I personally 
would stay away from the flexibilty of VLANs (as seen in another 
posting) because itcan be quite tricky if you don't work with them 
frequently.
