Tunnel Lining Segment Mold

Tunnel Lining Segment Mold is tailor-designed for the production of precast concrete lining segments in shield tunneling.

The quality of the formed tunnel structure is inseparable from the quality of the precast concrete segments, while the quality of the segments depends to a large extent on the quality of the steel segment mold.
