Mould and tile inspection Mould and tile inspection Laser scanning tackles tight tolerances in tile manufacturingProducing roof tiles to within half a millimetre demands precise quality control. At BMI Group, a new LK laser scanning system streamlines mould and tile inspections, tackling wear issues and ensuring consistent production accuracy.

(Source: LK Metrology)Few people outside the tile-making and building industry know that a good quality roof tile has to be manufactured to a tolerance as tight as plus or minus half a millimeter. Together with a rotatable, 300 mm diameter Freedom Index Table, the lightweight carbon fibre arm is mounted on a metrology table, all elements supplied by LK.
