We machine and cast automotive prototypes in metal and plastic: brackets, housings, engine-side parts and EV components. Tolerances to ±0.005 mm, 100% inspection before shipment, and DFM feedback inside 12 hours.
Most delays start before the first chip is cut. These are the ones we see on incoming RFQs.
Datum faces get modeled as cosmetic surfaces, so the CMM report has nothing to hold. A bracket checks out on the bench but not against the fixture. We flag missing datums during DFM review and confirm the datum scheme before machining starts.
A 0.8 mm cast wall or a 1.2 mm machined rib warps after the first thermal cycle. The part looks right in CAD and fails on the road. Material and wall thickness decide the process, not the other way round.
You validate a machined block, then tool up for die casting. Shrinkage, draft and gate marks change the part. Where possible we keep the prototype on the same material family as the intended production route.
An as-machined Ra 3.2 μm face on a sealing surface leaks during pressure test. A polished face changes the friction reading. Finish is a functional spec, so we ask what the part has to do before choosing it.
Two capability areas decide most automotive prototyping jobs: the geometry you can cut in one setup, and how closely the prototype matches the production part.
Automotive parts are rarely simple prisms. Control arms, intake housings and motor mounts carry compound angles, drafted faces and bores that do not sit on one axis. Cutting them on 16 simultaneous 5-axis centers removes most refixturing, and every refixture adds stack-up error.
16 mill-turn centers cover shaft-type parts such as sensor bosses and motor shafts in one cycle. Turning and milling on the same machine keeps concentricity between a bore and a milled flat, which matters when a bearing or a seal sits on that face.
A prototype only earns its cost when the data transfers. If the production part is a machined aluminum housing, we cut 6061-T6 or 7075 and keep the alloy honest. If it is die cast, we can machine ADC12 or run a vacuum-cast tool so wall sections and draft angles stay close to the casting.
For large exterior parts such as bumper sections and trim, vacuum casting in a silicone tool gives a part with realistic wall thickness and texture at low tooling cost. Sheet metal covers brackets, heat shields and mounting plates where bend radii and hole positions drive the design.
Use the part function first, then the material. The process follows from those two answers.
| Part type | Recommended route | Why it fits |
|---|---|---|
| Structural bracket, mount | 5-axis CNC, aluminum | Load paths need real alloy properties |
| Motor or sensor housing | CNC or vacuum casting | Casting matches thin walls and draft |
| Bumper, trim, grille | Vacuum casting | Large exterior surface, low tooling cost |
| Heat shield, panel | Sheet metal fabrication | Bend radii and hole pattern drive design |
| Sealing test piece | CNC, controlled finish | Sealing face needs a defined Ra band |
| Fit-check mock-up | 3D printing | Geometry only, no load requirement |
One shop for the prototype and the low-volume build that follows.
Compound angles and drafted faces cut in fewer setups. Suits control arms, housings and motor mounts where datums must survive the process.
Prismatic parts on 27 three-axis machines, shafts and bosses on mill-turn centers. Good for brackets, adapters and sensor bodies.
Short-run metal and plastic prototypes with DFM feedback inside 12 hours and production able to start within 24 hours of approval.
Silicone-tool parts for bumpers, trim and ducting. Realistic wall thickness and surface texture without hard tooling.
Brackets, heat shields and mounting plates where bend radius, hole position and flatness carry the function.
Anodizing, plating, powder coating and bead blasting. Laser marking from 1.5 mm character height for traceability.
Sizes are the practical travel we quote against, not catalog maximums.

Raw material check, in-process monitoring and final inspection. Dimensional reports on request.
150 technicians, 127 high-precision CNC machines and a compliance center handling documentation and traceability.
Housings and covers where bore alignment and sealing faces carry the function.
Mounts and brackets cut from 6061-T6 or 7075 with load-path geometry intact.
Large panels cast in a silicone tool to production-like wall thickness and texture.
POM, PA and PEEK parts where temperature and chemical resistance decide the resin.
Start with the part function. If it carries load, machine it from the production alloy. If it is an exterior panel or a duct, vacuum casting gets you closer to the final wall thickness at lower tooling cost.
If the part is a fit check only, 3D printing is enough. Send the CAD and we will tell you which route we would run and why.
Yes, on critical features such as bearing seats, bores and mating faces, provided the datum scheme is defined on the drawing.
The tolerance is not free on every surface. A cosmetic face or a clearance hole does not need it, and specifying it everywhere raises cost without adding function.
Yes. There is no minimum order quantity, so a program can move from one prototype to a 10,000+ part run on the same process and inspection plan.
Keeping the same shop for both stages avoids a second process qualification and a second set of fixture costs.
A 3D model in STEP or IGES, a 2D drawing with datums and tolerances, the material or a performance requirement, and the quantity.
Tell us what the part has to do in the vehicle. That single sentence often changes our process recommendation more than the drawing does.
Uploads are secure and confidential. We work under NDA on request and hold ISO 27001:2022 for information security management.
Unreleased vehicle programs are common in this shop. Files stay inside the project team.
Anodizing in clear, color, hardcoat and conductive types; electroless nickel, zinc, silver and gold plating; powder coating and black oxide; bead blasting, tumbling, brushing and polishing.

Quotation and free DFM analysis come back within 12 hours. Production can start within 24 hours of approval, and parts typically ship in 3–5 days.
Timing depends on material availability and finishing. If a part needs hardcoat anodizing or plating, add that to the schedule before you commit to a test date.
