Evaluate before the next revision
Use prototypes to check fit, access and assembly behavior against the surrounding components.
AUTOMOTIVE COMPONENT MANUFACTURING
Custom Parts for
Automotive & EV Projects
Turn your next vehicle or EV design into housings, brackets, interfaces and validation fixtures. Manufacturing support for the first physical sample and the builds that follow.

WHY PROLEANMFG
Make each build
move the design forward.
Give your engineering team physical parts for the next fit check, fixture setup or assembly evaluation.
Connect the manufacturing routes
Combine machined housings and turned interfaces with sheet metal covers and brackets.
Plan beyond the first sample
Compare sample and repeat quantities while keeping drawings, finishing and inspection aligned.
APPLICATIONS & COMPONENTS
Hardware for the vehicle.
Fixtures for its development.
Build the part being evaluated and the hardware needed to hold, locate or assemble it.
Housings & interfaces
Motor and gearbox housings, covers, shafts, bushings and mating interfaces.
HOW IT SUPPORTS THE ASSEMBLY
Bearing locations, sealing faces and mounting features connect to the surrounding assembly.
EV mounting & enclosure parts
Power-electronics covers, battery-related mounting plates, brackets and supports.
HOW IT SUPPORTS THE ASSEMBLY
Clearance, fastening access and finished surfaces support the equipment layout.
Validation & assembly fixtures
Locating plates, test mounts, assembly aids and customer-designed fixtures.
HOW IT SUPPORTS THE ASSEMBLY
Repeatable locating and accessible clamping help your team carry out its evaluation.
MANUFACTURING SUPPORT
The process behind
the component.
Connect geometry, material and finish to the route that makes the part.
CNC machining
Produce housings, pockets, mounting faces and fixture geometry in specified metal or plastic.
Explore CNC machining ↗CNC turning
Make round interfaces, shafts, spacers and bushings with the specified fits and surface requirements.
Explore CNC turning ↗Sheet metal fabrication
Build covers, brackets and panels with bends, hardware and finish suited to the assembly.
Explore sheet metal fabrication ↗FROM DESIGN TO BUILD
Support for the first sample
and the next build.
Each stage answers a different engineering question.
- 01
Prototype
Evaluate fit, fastener access and the geometry most likely to change.
A physical design check
- 02
Pilot build
Bring the accepted revision, material and finish into an assembly evaluation.
A defined build specification
- 03
Repeat order
Carry the agreed specification, inspection requirements and quantity into subsequent builds.

MATERIALS & FINISHES
Match the material
to the component’s job.
Explore the starting points below, then select the exact grade and condition for your design.
| Material family | Component examples | Selection considerations |
|---|---|---|
| Aluminum alloys | Housings, covers and mounting plates. | Component mass, machined features and surface finish. |
| Steel & stainless steel | Shafts, fixture parts, brackets and interfaces. | Strength, wear, condition and corrosion requirements. |
| Engineering plastics | Guides, spacers, covers and evaluation parts. | Weight, contact conditions and the service environment. |
Bring the finish
into the part design.
Account for coating thickness on fits, threads and mating faces. Identify cosmetic surfaces, masking and corrosion requirements alongside the finished dimensions.

QUALITY & INSPECTION
Give critical features
the attention they need.
Connect the inspection plan to the bearing fits, mounting datums, locating features and finished dimensions that affect assembly. Share any customer-specific submission requirements with the drawing.
- Drawing-based dimensional inspection
- Material and finish requirements in the component review
- Project-specific reporting agreed with your order
Your questions.
Practical answers.
Can I compare prototype and repeat quantities?
Yes. Include the initial quantity and expected next run, with any likely design changes. This allows the quotation to separate the assumptions for each build.
Can you manufacture custom validation fixtures?
Share the fixture drawing, locating scheme, mating geometry and service conditions. Include the features that need verification for your test or assembly setup.
Can I request PPAP, FAI or customer-specific records?
Provide the required documents and submission scope with the inquiry. Availability, inspection work and supported deliverables need explicit agreement before ordering.
How are safety-related applications reviewed?
Include intended use, applicable qualifications and customer requirements. Feasibility and the supported manufacturing scope are reviewed for the specific component.
