Raumatech combines European OEM engineering discipline with a mature Yangtze Delta supply chain — field service, spare parts and roll engineering, localized for the mills that keep the paper industry running. Every diagnosis from measured data, every recommendation from computation, every job closed with a written report.
Request a quote Explore field serviceRaumatech was founded by engineers trained inside European paper-machine OEM service organizations. We work on Valmet, Metso, Andritz and Voith machines every week — and we brought the discipline home: measure first, compute before recommending, and close every job with a written report.
Behind Raumatech stands a manufacturing base in the Yangtze Delta: a ~90-person non-standard roll manufacturer with new-roll, repair and grinding workshops, led by a founder with 20 years in production management and mechanical CAD / simulation engineering. Field engineers and roll engineers are the same people you talk to; there is no call-center layer between your machine and the person who fixes it.
From the headbox to the reel — you coordinate one partner instead of a spare-parts vendor, a contractor and the OEM separately.
Crown grinding, dynamic balancing, re-covering and bearing & journal repair for every class of paper-machine roll; complete overhauls of fiber-line equipment — cooking, washing, screening, refining — with critical parts remanufactured to OEM drawing dimensions and process standards.
Explore roll engineering →Startup commissioning, running-fault diagnosis, emergency repair and roll-position retrofits with operation optimization. Vibration, temperature and dewatering problems diagnosed on site — plus operator and maintenance-team training, so your crew holds the gains after we leave.
Explore field service →OEM-equivalent and domestic-substitute parts, roll-specific components and a structured consumables catalog — recommended against your actual operating conditions, not a generic list. Shorter lead times, lower inventory cost, every part traceable.
Explore spare parts →Roll-profile selection, nip-load and dewatering verification, fiber-line energy-saving and capacity upgrades. Assessment and expected benefit back to you within one week — and support through project approval and implementation, not just a report.
Request an assessment →Every engagement runs the same loop, so you always know where your machine stands.
Engineers, machinists and analysts who have commissioned paper machines, ground their rolls and written their reports — organized around what can be measured, computed and verified.
Precision crown grinding, dynamic balancing, re-covering and bearing & journal repair across the full paper-machine roll range — plus paper-machine guide rolls and vacuum rolls, and rolls for the lithium-separator industry. CFRP shells are CLT-designed and FE-verified, with plating and spray surface treatment developed in-house. Behind it: a ~90-person Yangtze Delta workshop — new-roll build, repair and grinding under one roof.
Two decades serving paper mills and roll programs — tissue-machine commissioning, Yankee service, roll-position retrofits and multi-base overhauls delivered across China and Asia-Pacific, including an overseas roll workshop taken from installation to trained staff and first production in just three months. Long-standing cross-border coordination with Swedish, Polish and British engineering resources; 30+ vetted local subcontractors under one accountable project manager.
In-house flow, deflection and nip calculation behind every recommendation; an AI knowledge base that converts each completed job into a reusable engineering asset; agent and low-code tools that put computation in the engineer's hand at the machine; ERP-grade process discipline from quotation to invoice — so advice is arithmetic, not opinion.
Vibration analysis on VMI-class instrumentation — spectrum, waveform, envelope, phase, bump test, run-up / coast-down, thermal imaging and current signature — plus on-site dynamic balancing of dryers, fans and rotors without dismantling, and analyst training for your own maintenance team. Every diagnosis lands in a written report, with the data behind it.
工程的本质，在车间里兑现
Strip it down and a mill needs three things: rolls that run steady, failures answered fast, costs that add up. That is the whole list. Know-how is data and process — it has no passport. We take the engineering methods of Nordic OEMs apart, verify them, and rebuild them here: capability, tooling and spare parts developed locally, every cost item traceable. No ocean freight, no layers of agents — price returns to material, labor and trust. World-class has one acceptance test: your mill floor.
