One-stop contract manufacturing
Manufacturing on Demand for the eVTOL Industry
We machine rotor arm nodes, motor mounts and landing gear fittings in Ti-6Al-4V and 7075 aluminium, and weld battery trays from sheet. ISO 9001:2015 certified, RFQ answered in 24 hours.
Build eVTOL Hardware Without Waiting on Tooling
Three things you get on every job, whether it is one part or a hundred.
One supplier, every process
CNC machining, vacuum casting, injection moulding, sheet metal and 3D printing in one factory. A project never gets handed between suppliers halfway through.

Weight and Fatigue in eVTOL Structures
An eVTOL airframe is mass-limited: every gram of structure is a gram of battery removed. Rotor arm nodes and motor mounts also see oscillating load at rotor frequency for the whole flight, so fatigue life, not static strength, sets the section. That is why the parts arrive as Ti-6Al-4V and 7075-T6 machined from solid rather than castings. Designs iterate hard before flight test, so we cut each revision in 2 to 7 days, hold +/-0.01 mm on bearing bores and motor mounting faces, and run the frozen version in batches of 7 to 15 days. Most eVTOL work here is prototype and low volume rather than production runs of thousands.
eVTOL Parts We Make Most Often
- Rotor arm nodes machined from Ti-6Al-4V billet
- Motor mounts in 7075-T6 aluminium, +/-0.01 mm bores
- Landing gear fittings in Ti-6Al-4V, 5-axis milled
- Battery trays in 2 mm aluminium sheet, TIG welded
- Control horns and linkage brackets in 7075-T6 plate
- Airframe brackets in 7075-T6, pocketed to 1.5 mm walls
The eVTOL Teams We Build Parts For
- eVTOL startups building first flying prototypes
- Airframe design houses iterating rotor arm nodes
- Electric propulsion suppliers making motor mounts
- Battery pack integrators needing welded trays
- Iron-bird and ground test rig builders for eVTOL
eVTOL Manufacturing Capabilities
CNC Machining for Rotor Arms and Mounts
3, 4 and 5-axis milling and turning in Ti-6Al-4V and 7075-T6, held to +/-0.01 mm. Rotor arm nodes, motor mount rings and landing gear fittings come off the 5-axis in one setup, so bearing bores and mounting faces stay square to each other. Pocketing down to 1.5 mm walls keeps mass off. Prototypes in 2 to 7 days, low volume in 7 to 15.
Vacuum Casting for eVTOL Cabin and Duct Parts
Silicone tooling off a machined or SLA master gives 10 to 50 parts in 5 to 7 days. Used for eVTOL interior panels, ducting, motor cowlings and sensor housings where the structural load is low and the part is large but thin. Polyurethane resins match ABS or PC stiffness, and rubber-like grades cover gaskets and grommets on battery trays.
Injection Moulding Once eVTOL Designs Freeze
Aluminium and steel tooling cut in-house, first shots in 15 to 30 days. Worth it on eVTOL parts that repeat per aircraft in quantity: cable clips, connector housings, ducting, avionics trays and interior trim. Glass-filled nylon 6/6 and PC/ABS cover most of them. Below a few hundred sets, vacuum casting is usually the cheaper route.
Sheet Metal for Battery Trays and Enclosures
Laser cutting, CNC bending and TIG welding from 0.5 to 6 mm. eVTOL battery trays, avionics boxes, firewall panels and bulkhead skins go this route because a folded and welded box weighs less than a machined one at the same stiffness. Aluminium 5052 and 6061 for weight, stainless where heat or fire containment matters.
ISO 9001:2015 certified, with in-house CMM and dial-indicator inspection. Every batch ships with a dimensional report, and material certificates are traceable to the batch or heat number on request.
eVTOL Manufacturing Services
CNC machining
Most eVTOL structure lands here. Ti-6Al-4V for rotor arm nodes and landing gear fittings, 7075-T6 for motor mounts, control horns and airframe brackets. 5-axis work holds +/-0.01 mm across the bore-to-face relationships that set rotor alignment. Thin-wall pocketing and stress relief between roughing and finishing keep 7075 flat after machining.
Vacuum casting
Silicone tools from an SLA or machined master, 10 to 50 parts in 5 to 7 days. On eVTOL programmes this covers cowlings, ducting, cabin panels and sensor pods for fit checks and ground demonstrators. Polyurethane resins in ABS-like, PC-like and rubber grades, cast in colour or painted to match the airframe.
Injection moulding
Aluminium tooling for short runs, steel where the part repeats across a fleet. First shots in 15 to 30 days. On eVTOL builds it suits the small parts that appear dozens of times per aircraft: cable clips, connector shells, vent louvres, avionics trays. Glass-filled nylon 6/6 and PC/ABS cover most of them, PBT next to motors.
Sheet metal
Laser cut, CNC bent and TIG welded, 0.5 to 6 mm. eVTOL battery trays, avionics enclosures, firewalls and skin panels. 5052 and 6061 aluminium where mass is the constraint, 304 and 316 stainless around motors and battery packs. Welded trays are flattened after welding so the cell stack sits true.
3D printing
SLA for masters and fit-check parts overnight, SLS nylon for ducting, brackets and cable trays that fly on demonstrators, and metal printing in Ti-6Al-4V for topology-optimised rotor arm nodes and lattice mounts that cannot be milled. Printed parts are used to prove the geometry before we commit to billet.
