Medical Device Enclosure Fabrication – Immunoassay Analyzer
Precision Sheet Metal – Welding – Rivet Assembly

LEO ELECTRONICS (VIETNAM) specializes in the fabrication of medical device enclosures, with a strong focus on enclosures for immunoassay analyzers used in hospitals and laboratories.
All processes—from precision sheet metal fabrication and accurate bending to welding and rivet assembly—are carried out under an in-house integrated production system, ensuring stable quality for mass production.

Integrated Manufacturing of Medium-Size Medical Device Enclosures

The product shown is an immunoassay analyzer enclosure with dimensions of approximately 1m × 1m × 1m and a weight of 70–80 kg, classified as a medium-size medical device enclosure.

LEO ELECTRONICS provides complete in-house processing, including:

Sheet metal fabrication

Precision bending

Robot welding and spot welding

Rivet assembly

By combining high-precision bending technology with robotic welding, the company achieves a stable production capacity of 200 units per month, suitable for mass production projects in the medical device industry.

Precise Bend Angle Control – The Foundation for Stable Rivet Assembly

For riveted joints, the most critical requirement is achieving an accurate 90-degree bend angle.
LEO ELECTRONICS uses NC bending machines equipped with angle sensors, enabling real-time measurement and adjustment of bend angles.

This approach allows:

Elimination of post-bending correction processes

No need for re-riveting

Significant reduction in defect rates and dimensional deviations

This precise angle control is a key factor in ensuring assembly stability and consistent product quality.

Dissimilar Material Welding Capability – Stable Operation

The company is capable of spot welding between stainless steel and steel, a technically demanding process due to differences in material properties.
Through strict control of welding conditions and optimized welding sequences, the welds achieve:

Stable mechanical strength

Minimal deformation

Suitability for high-precision medical device enclosure structures

Core Strengths in Medical Device Enclosure Fabrication

High-precision bending using angle sensors, with accuracy of ±0.2°

Stable rivet assembly with no additional post-processing required

Robotic welding with optimized welding sequences to minimize distortion

Spot welding of dissimilar materials: stainless steel and steel

Automated deburring to ensure safety and quality

Strong focus on exterior appearance, using dedicated carts and jigs to prevent scratches

Capability to assemble enclosure structures consisting of more than 60 components, including purchased parts
