The Vysočina Region is geographically the heart of Czechia, but industrially it has two dominant cores: Bosch Diesel in Jihlava (the largest Bosch plant in CZ, one of Europe's largest common-rail production sites) and JEDP Dukovany (the oldest Czech nuclear power plant, today ahead of planned expansion by block 5). For an integrator that means two radically different supplier worlds in one region — one is IATF 16949 and the Bosch Production System, the other is SÚJB and nuclear safety legislation.
Bosch Diesel Jihlava — common-rail on the global scale
Bosch Diesel in Jihlava, with around 5,500 employees and annual production of more than 6 million common-rail injectors, is the largest Bosch plant in CZ and one of three global production centres for the Bosch CRDI portfolio (alongside Bamberg in Germany and Wuxi in China). They produce piezo injectors for diesel engines, high-pressure pumps (CP4, CP4.2), pressure accumulators (rail), and from 2023 also components for hydrogen fuel-cell systems.
For an integrator the Bosch environment is defined by the Bosch Production System (BPS) — an internal six-sigma-based system that's a non-negotiable ritual for a supplier. NDA comes before the first email, Bosch Supplier Onboarding (including the Bosch Engineering & Business Conduct Code) comes before the first site visit, and PPAP via the internal Bosch portal (Bosch SupplyOn) comes before the first delivery.
For us Bosch Diesel is interesting through precision metrology and MES integration. The piezo injector for common-rail is a component with tolerances in nanometres — every unit undergoes individual calibration of the injection profile, recorded with the full production genealogy. That means: integration of calibration rigs into MES (Bosch internal stack, mostly built over SAP ME + custom extensions), AOI inspection of surfaces, X-ray inspection of solder joints, and full RFID traceability of every unit.
Our `automotive-injection-line` project (Bratislava, 2024) is technologically closest to what the Bosch supplier orbit might need — Engel, KraussMaffei, Yushin under Siemens TIA Portal with Ignition SCADA. For Bosch as prime customer it's a subcontractor model via a certified Tier-1 partner.
JEDP Dukovany — 4 VVER-440 reactors + planned block 5
JEDP Dukovany has 4 VVER-440/213 reactors (commissioned 1985-1987) with a total installed capacity of 2,040 MW. ČEZ has been preparing the construction of block 5 since 2023 — Dukovany 5 — with planned commissioning around 2036. The main candidate for delivering the reactor is the Korean KHNP (Korea Hydro & Nuclear Power) with the APR1000 block.
For an integrator Dukovany is an environment with full nuclear regulatory geography — SÚJB as the supervisory authority, IAEA protocols, and specific Czech decrees for work in the nuclear perimeter (SÚJB Decree 162/2017 on monitoring radiation conditions and Decree 263/2016 Coll. — the Nuclear Act). ČEZ as operator has its own QMS (ČEZ-IMS) under SÚJB specification BN-JB-1.6.
For us the realistic zone in the Dukovany nuclear circuit is: administrative IT (CAD/CAM, PLM system — usually Siemens Teamcenter or PTC Windchill), mechanical work outside the nuclear perimeter (warehouses, transport systems, canteen, ETB), and precision measurement for QA segments (UT, MT, X-ray). For core nuclear equipment we stay out — long-standing Czech suppliers with SÚJB certification (Doosan Škoda Power, Škoda JS Plzeň, Vítkovice Power Engineering, ČEZ ENERGOSERVIS) are the primary supplier model.
With the upcoming block 5 construction (expected start 2029) the supplier orbit will expand to new suppliers too — for an integrator that means a new segment in 2027-2030, where pre-construction work will open: temporary construction sites, modular accommodation capacity for the construction team (5,000+ workers at peak), temporary data centre capacity for the engineering team, temporary energy infrastructure.
Žďas, Mann+Hummel, Automotive Lighting
Žďas Žďár nad Sázavou is a steel forming complex — open-die forgings, rolling stands for rail vehicles, press lines. Classic Czech engineering with a tradition since 1951 (originally Závody Žďas Stalin). For an integrator it's an ASME-compatible environment with a large full metrological overlay.
Mann+Hummel in Nová Ves (Havlíčkův Brod district) produces air filters for automotive — IATF 16949 supplier orbit for VW, Mercedes, Bosch. Automotive Lighting in Jihlava (Magneti Marelli, since 2022 in Marelli Group / Calsonic Kansei) produces headlamps for Stellantis, FCA, BMW.
Our commuting relationship
From Prešov to Jihlava is 5 hours' drive on the D1 via Brno. For Jihlava and Vysočina we maintain Monday-to-Friday mode with accommodation for multi-day contracts. Accommodation best in Jihlava centre or Havlíčkův Brod.
We don't yet have a directly delivered project in the Vysočina Region. Our references from automotive injection (Bratislava, Stellantis supplier orbit) are directly transferable to the Bosch supplier orbit. For the nuclear periphery we don't have a current reference — Dukovany as prime customer is the world of certified long-term suppliers; we come either via a subcontractor model or via the "cold zone" of administrative and IT segments.
Which pillars fit best
For Bosch Diesel and the supplier orbit — **Industry + Automation + Software/AI**. Sondermaschinenbau, calibration rigs for piezo injectors, MES integration (Bosch internal stack), AOI and X-ray inspection, RFID traceability. Our specialisation in Engel, KraussMaffei, Yushin and Siemens TIA Portal is directly relevant to the Bosch supplier orbit.
For JEDP Dukovany — **Electro + Data Centres in the "cold zone"**. Cabling to administrative buildings, structured network, data centre capacity for the engineering team, fire systems outside the nuclear perimeter. For core nuclear equipment via a subcontractor model. For block 5 construction a new supplier segment opens in 2027-2030.
For Mann+Hummel and Automotive Lighting — **Industry + Automation**. IATF 16949 supplier orbit, robotic integration, MES integration.
For Žďas — **Industry + Electro**. ASME-compatible documentation regime, NDT integration, metrological overlay.
Conclusion
The Vysočina Region is about two cores: global Bosch (where they ask us "can you do it under BPS?") and the Dukovany nuclear complex (where they ask us "do you have SÚJB certification?"). Our answer to the first question is yes, to the second "only via a subcontractor model or in the cold zone". Response time for a site visit in the Vysočina Region is 5 working days.
