LKR

What LKR does

LKR d.o.o. is a privately held Slovenian family-owned manufacturer of special steel castings, operating from Kotlje and a production site in Ravne na Koroškem. The company produces technologically demanding castings in a delivery-weight range of 0.1 kg to 10 tons per item, using waterglass/ester systems for single pieces and small series, and the Shaw ceramic moulding system for highest accuracy and surface quality demands. LKR also offers flame-retardant ceramic products and processes specialty alloys including stainless steel grades, Hastelloy, Inconel, Monel, Ni-Resist D-2, and its own Ravloy, moulded to DIN/EN/ISO/ASTM/BS/JIS standards.

The integrated service model spans the full production chain from a single source: foundry, 5-axis CNC machining (with a 3000 mm mounting area and 10 t plate load), heat treatment in electric pit furnaces, model manufacture (including styrofoam 3D printing), computer-aided solidification simulation, EN 10204-certified quality assurance (destructive and non-destructive testing via RT/PT/MT/UT and spectrometer-based chemical analysis), and high-precision laser welding for finishing. The company targets industrial manufacturers across energy, chemical processing, mining, paper, sugar, cement, glass, and construction requiring geometrically complex or high-specification castings.

LKR generates revenue through one-off custom casting orders and associated professional services (machining, heat treatment, laser welding, model manufacture, simulation), priced via direct quotation rather than published tiers. Distribution is direct-to-manufacturer enterprise field sales with multilingual support (Slovenian, English, German, Russian websites). The company is bootstrapped and founder-led by Ivan Oto, with his son Rok Oto as Technical Director; no external investors or parent entity are disclosed. Operational signals include active recruitment, an EU co-financed digitalization project (E-POSLOVANJE 2019-2022), and TUV/Bisnode AAA certifications.

Revenue model

1. Custom Casting Production: LKR produces technologically demanding castings from 0.1 kg to 10 tons per item. Cast products are manufactured in their own production hall using waterglass/ester systems for single pieces and small series, and Shaw ceramic moulding system for highest accuracy demands. Full-service from product design support to final production.
2. CNC Machining Services: CNC machining including milling, turning, 5-axis machining, and finishing. Services include finish machining, pre-machining, component manufacture, and contract machining for cast and other precision components.
3. Heat Treatment Services: Heat treatment services (annealing, tempering, quenching) performed in electric pit furnaces for steel and cast iron, offered as part of the integrated production service.
4. Laser Welding Services: Precision laser welding applied to finished materials to correct small defects without causing deformation or dimensional deviations.
5. Solidification Simulation Services: Computer-aided simulation of casting processes offered to customers to detect weak spots before production, as an economic complement to field testing.
6. Model Manufacture Services: Model manufacturing for casting, using manual or conventional machines for simple parts and CNC-controlled lathes and milling machines for geometrically complex parts. Materials include wood, metal, plastic, and styrofoam 3D printing.
