Manufacturing Capabilities
One-Stop Custom Manufacturing Solution
Six core processes under one roof, so your parts move between operations without shipping, re-quoting or losing tolerance accountability.
CNC Turning
Swiss-type and CNC lathes with live tooling for shafts, connectors, bushings and threaded fittings — Ø0.5 mm to Ø320 mm.
5-Axis Machining
Simultaneous 5-axis milling for impellers, turbine components and complex aerospace geometries — tolerance down to ±0.005 mm.
Sheet Metal Fabrication
Laser cutting, CNC bending, welding and hardware insertion for enclosures, chassis and control cabinets. 0.5 – 12 mm sheet thickness.
Surface Finishing
Anodizing, passivation, bead blasting, powder coating, electroplating and laser engraving — 20+ finishes with colour matching.
3D Printing & Prototyping
SLA / SLS / MJF and metal DMLS for functional prototypes and low-volume bridge production — parts in hand within 3 days.
