We bring instruments, not just tools
Every diagnosis starts with data — taken on your machine, read by our engineers, kept in your report.
Paper machines, section by section — stock approach, headbox, shoe press, suction rolls, size press & coating, dryers, calender and reel. Every job measured, computed and closed with a written report.
Every position covered with OEM-level measurement tools and in-house engineering calculation. We carry the instruments and the models; you get the numbers.
Basis weight and consistency start upstream of the headbox — we treat the approach system as a measured hydraulic circuit, not a black box.
Result: CD profile ±1–2% improvement, splash-free jet stability, up to 30% less broke at start-up. All settings backed by in-house flow calculation of the header and nozzle — not trial and error.
Nip data first: loading curve, deflection and roll crown cross-checked against our deflection calculation before the shoe goes back in.
Drilling pattern and vacuum profile reviewed together — dewatering changes are engineered from measured data, not habit.
Starch / coating film uniformity starts with nip and synchronization data — Sigma-Nip readings close every sizing or coating job.
Temperature maps and ovality readings go into the job report — the basis for crepe-ratio gains of 15–25%.
Crown curves are re-computed from measured deflection before re-covering — see roll engineering for the design chain.
Wood handling, pulping and utility equipment — a compact family we cover alongside the paper machine.
Feed rotor and housing wear repair.
Screen basket and foil renewal, screw repair.
Roll surface repair, bearing and seal replacement.
Knives, bottom knives and disc assembly.
Wear-lined chutes and discharge valve parts.
High-chrome / ceramic wear plates made to print.
Also in the family: refiners (rotor/stator and filling parts), stock conveying (pumps, valves and piping), boilers, lime kilns and causticizing inspection.
Surface grinding and spray coating; thermal-imaging temperature mapping; crown and ovality inspection; suction pick-up roll crown optimization. Targets: ±1 °C/m temperature uniformity, 0.05 mm/m ovality after grinding, 15–25% crepe-ratio gain.
Steel and carbon-fiber creping blades; blade holders and backup system with edge-angle and loading calibration. Shoe-press sleeves and grinding; hydraulic seals and loading systems.
Vacuum box covers and siphons; drilling repair and seal-strip renewal. Yankee face service: spray coating, grinding, steam joint and rotary siphon parts.
Every diagnosis starts with data — taken on your machine, read by our engineers, kept in your report.
In-house calculation tools turn field measurements into defensible recommendations — computation, not marketing.
FlowCalc — manifold, header and nozzle calculation supporting CD basis-weight optimization and approach-system troubleshooting.
Finite-element checks of shell, journal and nip loading — the basis for crown design and covering selection.
Nip pressure distribution and wet-end forming parameters — sizing and coating setpoints from calculation, cross-checked with Sigma-Nip readings.
CLT / FE analysis of composite roll structures rounds out the toolset — see carbon-fiber rolls.
Six steps, each one visible — you always know what happens next and what it delivers.
