華井氮化硅精密陶瓷輿石墨材質相比，不曾被氧化腐觸及磨損燮形，即便長期使用也能保持其最初的性能，可以幫助客戶減少更換頻率，降低生產成本。

華井自主研發的轉子葉輪結構可以輩助氣體在鋁溶液中充分均勻擴散，同時可以減少進氣量，有效防止鋁液形成漩渦，出色的除氣效果提高了產品品質的穩定性。

Huajing Silicon Nitride ceramic rotor shaft exhibits exceptional wear and oxidation resistance compared to a graphite rotor. It assures stable high hydrogen removal efficiency for a long service life, and it can reduce the frequency of replacing new parts, so that help customer have good cost savings. The impeller structure design of rotor shaft, help the gas spreading evenly in the aluminum solution, at the same time, reduce the gas into the solution, prevent the whirlpool shaped. The high gas dispersibility makes hydrogen removal efficiency superior, as a result, improve the quality of die casting parts.
