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.
Process repeatability
Fixtures, machining sequence and in-process checks are planned for the required batch.
Evidence by agreement
Material and inspection documentation are defined at RFQ rather than assumed.
DESIGN FOR MANUFACTURING
A useful quote identifies risk—not only price.
For automotive motor components 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.
01Motor housings
Machined aluminum bodies with controlled bores, faces and assembly patterns.

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.
MANUFACTURING SERVICES

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.
Is WEKO IATF 16949 certified?+
WEKO publishes an IATF 16949 certificate in its company information. Buyers should verify the certificate’s current validity, named legal entity, manufacturing address and scope against the documents supplied for their project.
Can WEKO support automotive production quantities?+
Repeat-production requirements can be reviewed. Feasibility depends on part geometry, material, annual volume, quality plan, capacity and commercial requirements.
Can PPAP or automotive documentation be provided?+
Required documentation must be listed in the RFQ. WEKO will confirm which elements can be supported for the specific project before order placement.
How are special characteristics controlled?+
The customer should identify them on the controlled drawing or specification. Process and inspection planning are then reviewed and agreed before production.
