What J. & F. Kruth does

J. & F. Krüth GmbH is a family-owned German industrial service company founded in 1969 in Solingen, specializing in surface engraving technologies for injection-molding, blow-molding and die-casting tools. Its core offering combines three complementary processes — traditional ÄtzGravur (chemical etching), Laser-ÄtzGravur (hybrid digital/acid) and fully digital 3D-LaserGravur on a five-axis fiber laser — together with proprietary surface finishing products (NiOn100/NiOn200 chemical nickel coatings, mono/double-gloss nickel shell finishing, VORTEX® and Porcerax II® venting steels). The company is directly engaged in CMF (color, material, finish) development with automotive OEMs and Tier-1 suppliers, producing sample plates, feasibility studies on CAD data and digital film-coating previews before tooling is committed.

Krüth generates revenue through project-based B2B professional services: each engagement typically spans design consultation, feasibility, texture mapping, laser or acid engraving of tool surfaces, and optional finishing or coating. Pricing is not publicly disclosed and is customized per project based on technology, depth, material and volume. Go-to-market relies on direct enterprise field sales to automotive OEMs (Audi, BMW, Porsche, VW, Mercedes-Benz, Volvo, Ford, Jaguar, Renault, PSA/Stellantis, MAN) and Tier-1 suppliers (Faurecia, Adient, Joyson Safety Systems, Grupo Antolin, Hella, Kostal), with secondary exposure to consumer goods (Adidas, Braun, Miele, Tupperware, Vorwerk) and chemicals (BASF, Covestro). International reach is delivered through wholly-owned subsidiaries in Portugal (since 2015) and Austria (SET-Krüth, 20+ years), the Global Laser Group network (founded 2017, 30+ laser machines globally) and the Surface Etching Cooperation (SEC) network spanning Europe, the Americas and Asia.

The firm operates from five production locations across Germany (Solingen Werk I/II, Pfedelbach Werk III), Portugal and Austria, holds TISAX® and ISO 9001 certifications, and is led by managing directors Stefan Krüth and Martin Krüth with Petra Engstle as Marketing & Sales Director. Customer engagements frequently involve two-to-three-week international project assignments at subsidiary sites, and Krüth runs an internal apprenticeship program for Industrial Engravers to preserve a craft specialty rooted in 19th-century Solingen Damascus-steel etching traditions.

Products and services

• 3D-LaserGravur (3D-LaserEngraving) Fully digital five-axis fiber laser technology service for applying engravings directly to mold steel surfaces in all dimensions using successive layer ablation. Produces three-dimensional engravings with 256 greyscale depth control, enabling virtually unlimited design options including morphing engravings, ERO structures, Easy-to-clean structures, and LimitedReflection anti-glare engravings. Used by automotive OEMs, Tier-1 suppliers, and consumer goods manufacturers for plastic components.
• Laser-ÄtzGravur (Laser-EtchingEngraving) Hybrid engraving technology service combining digital laser transfer with traditional acid etching. The laser creates a protective enamel pattern on the tool, followed by acid bath ablation of exposed areas. Bridges traditional craftsmanship and digital manufacturing for automotive and consumer goods plastic component tools.
• ÄtzGravur (EtchingEngraving) Traditional acid etching engraving service using wax print or multilayer films for design transfer, followed by acid bath ablation to create engravings on tool surfaces. Heritage technology originating from Damascus steel traditions, refined for modern injection molding, blow molding, and die-casting tools.
• NiOn100 Coating Chemical nickel dispersion coating service with uniformly distributed non-metallic PTFE particles. Provides anti-stick finish and improved ejection properties, reducing friction in the mold. Complements engraving services for automotive and consumer goods injection molding tools.
• NiOn200 Coating Nickel-phosphorous (NiP) chemical coating service providing high wear protection and corrosion resistance. Achieves coating thickness up to 100 µm evenly with no edge buildup. Used for dimensionally stable components and cooling channel protection in injection molding tools.
• VORTEX® Venting Steel Supply Supply and processing service for air-permeable sintered steel (VORTEX®) with uniform micro-porosity (avg. 7 µm pore size, up to 20 µm; ~25% porosity) allowing air and gas to escape through the mold itself. Produced by Molder's World and applied by KRÜTH in combination with 3D-LaserGravur for venting optimization and process security in injection molding.
• Mono- and Double-Gloss Nickel Shell Finishing Post-engraving surface finishing service that assigns differing gloss values to crests and valleys of nickel shells, enabling more authentic replication and higher quality visual appearance in mass-produced items. Used with consumer goods and automotive component molds.
• Scanning Services High-resolution 3D scanning service for reproducing smallest details in grey scales during development stage verification of engraving projects. Used as a quality verification step before and during tool surface engraving.
• Measuring Services Precision measuring service using FRT MicroProf 100 and Nanofocus interferometric systems for 2D/3D surface measurements with chromatic distance sensors. Used for verification of engraving depth and surface quality.
• Testing Services Quality testing service including digital dial gauges for structure depth, optical microscopy up to 400x magnification, and interferometric measurement for engraving passport documentation. Used to verify engraving conformance to specification.
• Surface Service (Polishing & Welding) Surface treatment service including polishing work and welding repairs (laser and TIG processes), plus on-site technician support for mold service. Offered through SET-KRÜTH Austria subsidiary and KRÜTH facilities.
• Design Development Services Surface design consulting service covering appearance, haptics, acoustics, and functional requirements. Includes engraving with functional properties (anti-slip, anti-creak, light-absorbing), design team concept development, and sample plate creation for evaluation before production commitment.
• Texture Mapping / Digital Film Coating Digital pre-production service projecting engravings onto CAD tool surfaces for perfect geometry adaptation and cross-component texture mapping. Delivered as animated 3D PDFs for customer review and visual assessment of engraving distribution, including component-related stretching effects.
