Limpahan
Limpahan's capability transcends commodity CNC. Three integrated columns — subtractive precision, additive prototyping, and metrology — spanning CAD design, machining, fabrication, 3D printing, 3D scanning, and traceable inspection. Every machine listed here is on the floor today.
The Mazak 5-axis multi-tasking machine is the most advanced spindle on the Limpahan floor and the anchor of the AS9100D aerospace programme. Q3 2026 brings 4 more 5-axis machines — a 5x capacity multiplier.
Five axes, simultaneous. Programmed in Siemens NX, fixtured once, machined to micron tolerance. Aerospace impeller forms, turbine blades, complex curvature parts — geometry that 3-axis machines cannot produce in a single operation.
Compressor and turbine wheels machined complete from billet, no welding seams.
Complex airfoil profiles in titanium and stainless — aerospace and APU work.
Hydrogen reactor manifolds and aerospace structural components, single-fixture.
Tier-1 aerospace primes (Airbus, ATR) require 5-axis for sub-tier supply.
The machining floor — HAAS, Mazak, and Excetek — runs aerospace, hydrogen, semiconductor, and oil & gas parts to micron-level tolerance.
Two mirrored super-speed vertical mills running in parallel for repeat aerospace and hydrogen part production. The workhorses of the floor.
Large work envelope for reactor frames, electrolyzer compression plates, and oversized aerospace tooling.
Y-axis live tooling consolidates turn / mill / drill / tap into a single setup. Higher accuracy and shorter cycle times on shafts and rotational components.
Aerospace impeller, turbine-blade, and complex curvature geometry — all in a single fixturing. The anchor of Limpahan's AS9100D-aligned aerospace work.
Sharp internal corners, narrow slots, and complex tool / die geometry that conventional cutters cannot reach — held to micron-level tolerance.
Material envelope: stainless steel (304, 316), aluminium 6061-T6, titanium-grade alloys, PTFE, engineering plastics, tool steel. Wenzel CMM dispatch reports issued for aerospace lots.
Limpahan's ethos transcends subtractive machining. Additive manufacturing, 3D scanning, and fabrication are first-class capabilities — not afterthoughts.
Rapid prototyping, jig & fixture printing, short-run housings, and design-for-manufacture iteration before metal is cut. Cuts validation cycle time on hydrogen and aerospace geometry.
Reverse engineering, dimensional inspection, and rapid as-built capture using advanced 3D scanning technology. Lab-to-production geometry without lossy interpretation.
Comprehensive fabrication for structural supports, custom industrial builds, electrolyzer chassis, and reactor frames — assembled and dispatched as turn-key subsystems.
Tok Bali Supply Base — equipment repair, system overhaul, refurbishment, and on-site installation, alignment, and commissioning for industrial and oil & gas operators.
The metrology spine of every aerospace, hydrogen, and semiconductor dispatch. Traceable dimensional proof, gauge R&R studies, and AS9100D-grade documentation.
Full 3D dimensional inspection with traceable measurement reports. The metrology backbone of the AS9100D quality system — every aerospace dispatch ships with a Wenzel report.
Off-spindle tool measurement and offset capture — predictable first-cut accuracy and no spindle time wasted on touch-off cycles.
Final-pass flatness for sealing surfaces, electrolyzer bipolar plates, and tool / die inserts demanding sub-micron surface finish.
Gauge Repeatability & Reproducibility studies, measurement system analysis, and per-part traceability records. The documentation foundation of UKAS AS9100D, ISO 9001, and ISO 45001.
Limpahan engineers in the same CAD platforms as the customers we ship to — geometry travels from drawing to spindle without lossy translation.
Aerospace-standard surface modelling and assembly design. Used for impeller forms, complex curvature, and tier-1 aerospace deliverables.
Day-to-day mechanical design across hydrogen, semiconductor, and oil & gas parts. Linked CAM and FEA for design-for-manufacturability.
5-axis CAM toolpathing on the Mazak platform. Simulation, post-processing, and complex multi-axis machining strategy.
