Aluminum Alloy Fan Rotor End Cap

Customized High-Quality Die-Cast Motor Rotor End Caps

Precision zinc/aluminum alloy rotor end caps and fan covers. High-strength engineering that ensures flawless balance, rotation stability, and critical dimension controls for electric motors.

Motor Housings & End Shields: Built as a Matched Set

The housing and end shield are not two separate parts — they are one system. If their fits are machined by different suppliers, you inherit their tolerance stack-up. We cast and machine both, so the bearing bores, sealing faces and bolt patterns line up by design.
 
What we control on every set:
 
– Bearing bore concentricity to the housing chamber, machined in one setup
– End shield spigot fit and bolt circle verified against the housing before shipment
– Wall sections designed around your stator, rotor and terminal layout
– 100% leak testing on sealed housings before packing
 
Send us your stator drawing or a sample motor — we will return a DFM review with the housing/end shield split, draft and machining allowances marked.

Frequently Asked Questions

Can you produce custom OEM motor housings and end shields from my drawings or samples?

Yes. Send us your 2D/3D drawings or a sample part — we start with a DFM review covering the housing/end-shield split, wall sections, draft angles and machining allowances. After your approval, tooling is developed by our vetted partner factories, and first samples follow 10–15 days after tooling completion.

Tooling development takes 35–45 days depending on part complexity. First samples follow 10–15 days after the tool is completed. For mass production, lead time is 30–45 days depending on order volume and finishing requirements.

Porosity control starts at the DFM stage — wall thickness, rib design and the gating/overflow system are reviewed before tooling is cut. During production, process parameters are controlled under the partner factory’s quality system, and every part passes 100% visual inspection with dimensional sampling to your drawing. Application-specific requirements are reviewed during DFM.

As-cast and machined surfaces are toleranced separately in the DFM review. Bearing seats and spigot fits are finished by CNC after casting to your drawing; CNC-machined features are verified by CMM (sampling per QC plan), and routine dimensions are checked with calipers and gauges.

Every part passes 100% visual inspection. Dimensions are checked by sampling to your drawing — CNC-machined features by CMM, routine dimensions with calipers and go/no-go gauges. Where parts carry a surface finish, coating quality is verified with cross-hatch adhesion, thickness and color checks.

YMost motor housings and end shields are aluminum (typical alloys such as ADC12/A380) for light weight and heat dissipation; zinc suits small, high-precision sections where surface finish matters most. The final alloy is confirmed during the DFM review based on your drawing.
