European technology sets the standard; our team and supplier network deliver it. We qualify suppliers, manage field service and roll work, and own parts quality — all on your behalf.
Request a quote Explore field serviceRaumatech is your engineering and supply-chain arm in China. Our founders trained inside Valmet, Metso, Andritz and Voith service organizations — and we work on those machines every week.
We replace three separate vendors with one accountable channel: OEM-equivalent roll remanufacturing and spare parts, shorter lead times, lower inventory, emergency field service, and engineering assessments with conclusions in one week.
Raumatech 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 professional-grade 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.
The essence of engineering, delivered in the workshop.
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.
