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
