Ultra-modern and innovative manufacturing system for the production of monolithic manhole bases with extremely smooth surfaces, flexible channel diameters, run-off angles and variable heights of inlets and outlets. The CAPITAN formwork system guarantees minimum wear and cuts cycle times within the production process to a minimum. The core of the CAPITAN system is the multi-axis milling centre with which the channel forms are machined in one piece. The milling programme is very quickly and easily set up with the configurator developed by BFS.
