Products Products M400 For small curvature radii Typically used for interiors, boat hulls, wind turbine blades. The M400 is made for the lowest curvature radii, and typically the lowest load per. sqm. M800 For medium curvature radii Typically used for exterior cladding panels and moulding sides for large casting. The M800 is an intermediary adaptive mould used as an all-round solution with capabilities for high sqm. (>10 sqm.) and relative low curvatures of 800 mm. M1200 For the large curvature radii Typically used for large buidling exteriors such as airports, museums and stadiums. The M1200 is made for heavier loads and the highest curvature radii. Handling up to a 16 cm layer thick wet concrete.
