What Global Buyers Say About Yongzhu Casting
Whether you’re a mechanical engineer, a sourcing specialist, or a project manager, our customers value what we deliver: consistent quality, responsive service, and reliable aluminum die casting solutions.
Our VTOL cargo drone switched from a machined 720 g billet shell to a 530 g die‑cast housing from Yongzhu Casting. Rotor hub temps dropped 9 °C and flight endurance rose 7 minutes on a 60 min mission—critical for last‑mile deliveries.
Marine radar pedestals on our coastal patrol vessels needed MIL‑DTL‑15024 compliance. The ADC12 die‑cast base with Yongzhu’s 120 µm powder coat survived 2 500 h ASTM B117 and retained torque at 600 N·m—no repaint between dry‑docks.
Casting the collaborative‑robot shoulder as a single 2.9 kg piece eliminated eight bolts and raised fatigue life from 3 million to 4.1 million cycles. Payload grew 0.4 kg without motor upgrade—a direct yield increase for our users.
Polymer housings distorted under hot pesticide. Yongzhu’s vacuum die‑cast aluminum body (1.6 kg) passed a 20 bar burst test and cut field leaks from 3.5 % to < 0.2 % across 45 000 units.
An extruded heat sink couldn’t shed 350 W in a fan‑less base‑station radio. The new topology‑optimised die‑cast sink from Yongzhu trims 15 °C off hotspot temperature, allowing full‑rate transmit in 45 °C desert sites.”
Our steel shell dented during 100 G SAE J1455 drop. The die‑cast aluminum enclosure from Yongzhu absorbed the shock with zero deformation and lowered harness weight by 0.8 kg, improving operator feedback vibrations by 18 %.
