Frequently asked questions

Can you machine battery cooling plates with internal cooling channels?

Yes. Top Proto machines battery cooling plate internal channels through CNC milling of channel geometry in one or both plate halves, followed by vacuum brazing or friction stir welding to close the channels. Channel dimensions, surface roughness, and plate flatness are specified in your drawing and confirmed by dimensional inspection. We also produce cooling plates from extruded aluminum profiles with integrated channel geometry.

What aluminum alloys do you use for new energy thermal management components?

For battery cooling plates requiring maximum thermal conductivity, we use aluminum 1050 or 3003 alloys. For structural battery module housings and power electronics enclosures where a combination of strength and thermal performance is needed, 6061-T6 is the standard choice. For die cast new energy components, A380 is the standard alloy with good fluidity and adequate thermal conductivity for most housing applications.

Can you produce EV motor housings by die casting?

Yes. Top Proto produces EV motor housings, stator carriers, and gearbox housings by aluminum die casting for production volume programs. Die cast motor housings are produced from A380 or ADC12 alloy, with post-cast CNC machining applied to bearing bore, stator bore, and sealing face surfaces to meet the tight tolerances required for motor assembly.

What surface treatment is used for EV battery enclosures?

EV battery module housings at Top Proto are typically Type II anodized for corrosion resistance and electrical isolation between battery modules and the vehicle structure. For outdoor-exposed battery enclosures on commercial vehicles, powder coating over an e-coat primer provides better weather and corrosion resistance. Surface treatment specification is reviewed during DFM to ensure dimensional allowances for coating thickness are included in the part design.

Can you produce hydrogen fuel cell stack components?

Yes. Top Proto produces hydrogen fuel cell stack clamping plates, bipolar plate interface components, and stack housing assemblies in stainless steel 316L and titanium. These materials provide the corrosion resistance required in hydrogen and proton exchange membrane environments. Surface finish and flatness requirements for bipolar plate interfaces are reviewed during DFM and confirmed by CMM inspection on first article parts.
