Telecommunication Equipment Enclosure Fabrication
Aluminum Processing × High-Precision Press-Fit × Black Textured Coating

We manufacture enclosure components for telecommunication equipment used in server racks and data centers.
From aluminum fabrication and high-precision nut insertion to black textured coating, we provide consistently high quality and stable supply for technically demanding processes.

Overview

LEO ELECTRONICS (VIETNAM) is a Japanese-owned EMS manufacturer based in Vietnam, specializing in the fabrication of enclosure parts and structural components for data center and telecommunication infrastructure equipment.
We respond accurately to design intent while ensuring stable quality and mass-production readiness.

By managing multiple processes in-house—including high-precision cutting using combination machines, nut press-fit insertion, welding, coating, and Alodine surface treatment—we deliver products that meet the strict quality standards required for telecommunication equipment.

In the nut insertion (press-fit) process, we optimize pressing force, insertion speed, and holding time, achieving stable retention even for parts that previously faced drop-off risks with other suppliers.
In addition, for structures where products are stacked or overlapped, uniform coating thickness of black textured coating is critical. Our coating quality control know-how is a key strength in ensuring defect-free performance.
