Precision Die Casting for High-Speed Optical Connectivity

In the world of optical communication and data centers, every micron of precision matters.

At Dongguan GuangWei Communication Technology Co., Ltd., we engineer high-precision zinc and aluminum alloy die-cast housings for next-generation optical transceivers — including SFP, SFP+, QSFP, QSFP28, QSFP56, QSFP-DD, and OSFP modules.

Advantages

Our die-cast enclosures are designed to deliver exceptional EMI shielding, dimensional accuracy, and thermal performance, ensuring stable transmission and mechanical reliability under the most demanding high-speed network conditions.

Unlike conventional stamped or machined housings, GuangWei’s die-cast solutions combine:

Excellent electromagnetic compatibility (EMC) — zinc alloy’s natural shielding properties reduce signal interference and crosstalk.

Outstanding thermal dissipation — aluminum and magnesium alloys efficiently manage the heat generated by 400G and 800G modules.

High structural integrity — precision molds guarantee stable alignment for optical connectors and PCB interfaces.

Superior surface quality — compatible with nickel, chrome, or black plating for both aesthetics and corrosion protection.

Reliable Data Infrastructure

Our engineering team collaborates closely with customers from mechanical design to mass production, optimizing wall thickness, heat paths, and grounding points to ensure signal stability and long-term reliability. Backed by IATF16949, ISO9001, and ISO14001 certifications, GuangWei’s optical communication enclosures are trusted by TE Connectivity, Luxshare, Huawei, and Cisco. We help global network innovators build faster, more efficient, and more reliable data infrastructures through precision die casting excellence.
