Client Voices

What Our Clients Say

Real feedback from global manufacturing clients. Over 2,800+ companies trust POAO.

Micro-channel cold plates manufactured using SLM metal 3D printing increased our cooling efficiency by 40% compared to traditional CNC, perfectly solving the thermal bottleneck of our high-compute servers.

🇨🇳

Wei Zhang

Server Hardware Co. · Hardware Director

The 3D-printed unibody water block completely eliminated the risk of leaks from traditional split joints. The complex 3D channel design is stunning.

🇺🇸

John Carter

DataVault Systems · Hardware Engineer

The lightweight design requirements for aerospace radar cooling plates are extremely high. The aluminum alloy 3D printing solution provided by the platform reduced weight by 30% while ensuring excellent thermal conductivity.

🇨🇳

Xiao Chen

AeroTech Beijing · Thermal Engineer

From uploading complex custom liquid cooling channel models to receiving perfect printed samples, it took less than a week. The air tightness test report was highly professional.

🇸🇪

Lena Bergström

Nordic Computing · R&D Manager

Custom liquid cooling parts for medical MRI equipment are highly challenging. Their copper 3D printing precision completely exceeded our expectations, leak-free with excellent heat dissipation.

🇨🇳

Mingkun Li

Suzhou Medical R&D · Project Manager

The iteration speed of liquid cooling micro-channel prototypes for EV battery packs doubled thanks to POAO. The online quoting system's evaluation of channel features is very accurate.

🇮🇹

Marco Ferretti

EV Power Italy · Thermal Architect

High-density cooling for AI servers has always been a challenge. With their custom 3D printed cold plates, we achieved more efficient thermal management with transparent pricing.

🇦🇪

Amir Hosseini

GreenTech ME · Technical Consultant

The casing printing precision for the micro liquid cooling pump was very high. The internal surface roughness was well controlled, minimizing fluid resistance.

🇨🇳

Qiming Wang

Guangdong OptoMech · Chief Engineer

Custom water cooling parts for consumer high-performance PCs are often hard to prototype, but here we not only did it, but the surface finish is exquisite, becoming a direct selling point.

🇸🇬

Sophie Tan

TechWear Singapore · Product Director

The engineering team provided a professional DFM report for channel optimization before printing, avoiding internal support residue issues. Such liquid cooling manufacturing experience is rare.
