Q1: Why are extruded aluminum profiles preferred over cast iron for electric motor housings?

A1: Aluminum profiles offer roughly three times the thermal conductivity of cast iron, allowing the motor to dissipate heat much faster and run cooler, which significantly extends the service life of internal windings. Additionally, aluminum reduces the housing weight by up to 60%, offers superior corrosion resistance, and provides a smoother finish straight out of the extrusion press.

Q2: How do you achieve the tight cylindrical tolerances required for the motor stator assembly?

A2: Electric motor assemblies require precise inner diameter (ID) tolerances to ensure a tight interference fit (shrink fitting) with the stator. Our factory combines premium, highly calibrated extrusion dies with secondary high-precision CNC lathe boring and internal honing procedures, enabling us to consistently maintain tight tolerances within ±0.02 mm.

Q3: Can you integrate custom electrical terminal box bases directly into the main housing extrusion?

A3: Yes, completely. During the cross-sectional die design phase, we can integrate the mounting tracks for the junction box straight into the profile structure. This eliminates the need for separate welding or mechanical fastening, reducing production steps and component costs on your final assembly lines.

Q4: What is your minimum order quantity (MOQ) for custom-engineered heat-fin geometries?

A4: For unique proprietary dimensions requiring custom tooling, the initial MOQ depends on the cross-sectional weight of the profile. We offer highly competitive pricing on initial die fabrication and provide full test samples before mass high-volume production begins.
