Precision and versatility in industrial laser contract manufacturing
KMLT GmbH is a specialized B2B supplier for laser micromachining based in Saxony and has been manufacturing customized, ready-to-install precision components since 1991. The range of services includes laser micro cutting, UKP laser processing with femtosecond lasers, laser fine cutting, distortion-free laser micro welding, laser marking and engraving, micro bending as post-processing, and surface treatment such as micro polishing, electropolishing, tumble finishing and nano coating. Products manufactured include filigree micro parts, watch and chronometer components, SMD and calibration stencils, shims, spacing washers and intermediate layers from 0.005 mm material thickness, medical technology components, EMC shields, miniature housings and laser-marked premium labels. Materials processed include metals, precious metals, plastics and functional ceramics; standard tolerances are up to ±3 µm with burr-free cut edges and no thermal distortion. Customers are quality-sensitive industries such as automotive, aerospace, watchmaking and luxury goods, micromechanics, medical technology, electronics manufacturing, sensor technology and microelectronics/semiconductors. With 26 specialized laser systems at its Dresden and Neukirch/Lausitz sites, the company provides everything from data preparation to laser cutting and metrological quality control from a single source – from prototype to large-scale industrial series, without tooling costs.
