WHAT THE APPLICATION DEMANDS
Control the features that control performance.
Each project is reviewed against its own geometry and risk. These are common engineering priorities—not universal tolerance claims.
Thermal paths
Wall sections, contact faces and surface conditions are evaluated around heat-transfer needs.
Outdoor durability
Material and finish callouts are aligned with corrosion, appearance and assembly requirements.
DESIGN FOR MANUFACTURING
A useful quote identifies risk—not only price.
For electric mobility components, the manufacturability review connects the 3D model to the drawing: datum structure, critical fits, wall sections, tool access, material condition, finishing and the measurement method.
- Confirm the released revision and units
- Separate functional requirements from cosmetic zones
- Identify assembly-critical bores, faces and threads
- Agree inspection evidence before production
COMMON COMPONENTS
Structural parts made from your controlled design.
WEKO supplies machined metal components only. Electronics, bearings, complete assemblies and product design remain with the customer or approved system supplier.

Review this partPROTOTYPE TO REPEAT PRODUCTION
Five stages, one controlled requirement.
Each stage answers a different manufacturing question before more time and material are committed.
RFQ & drawing review
Align revision, material, quantity, critical features and commercial requirements.
Prototype
Test manufacturability and functional interfaces using production-relevant material.
Engineering validation
Review fit, assembly, finish and inspection evidence; capture approved changes.
Production validation
Confirm fixtures, machining sequence, process checks and packaging on a controlled batch.
Repeat production
Run the released revision with agreed controls, documentation and change discipline.

MATERIAL & PROCESS MATCH
Choose the grade around exposure, fit and finish.
Final alloy, condition, certification and finish remain controlled by the released drawing and agreed quotation.
General-purpose structural aluminum
Aluminum 6061
A practical machinable alloy for motor housings, end covers, brackets and equipment structures where low mass, corrosion resistance and stable production matter.
Open material guide
Higher-strength lightweight aluminum
Aluminum 7075
A higher-strength aluminum option for weight-sensitive robot, drone, reducer and motion-system interfaces when the released design requires more mechanical performance than a general-purpose alloy.
Open material guide
General corrosion-resistant stainless steel
Stainless Steel 304
A widely used stainless grade for shafts, sleeves, end caps, clean structural interfaces and equipment hardware where general corrosion resistance and a durable metallic finish are useful.
Open material guide
Higher-corrosion-resistance stainless steel
Stainless Steel 316
A stainless grade often considered for demanding corrosion, cleaning or outdoor exposure around motion equipment, subject to the actual medium, temperature, geometry and released specification.

ENGINEERING FAQ
Answers before you send the drawing.
What electric-mobility components does WEKO supply?+
Typical scope includes CNC-machined motor housings, end covers, shafts, sleeves and structural mounting parts. WEKO does not supply finished electric drive modules or complete vehicles.
Can thermal features be included in machined motor housings?+
Yes, when defined in the released design. We review machining access, wall thickness, flatness, sealing features and inspection requirements before quotation.
How are fit-critical bores handled?+
Fit class, datum structure, surface requirement and inspection method must be specified. WEKO confirms the process and capability against the actual geometry.
Which finishes are common for electric-mobility parts?+
Anodizing, passivation, plating and as-machined surfaces may be considered. The exact specification, appearance zone and masking requirement are agreed during RFQ.
