Aluminum Frames and Fittings for Medical Analyzers

Requirement

The customer’s in-vitro diagnostic analyzers use aluminum frames to carry optical and fluidic modules. Frames must be easy to clean with no hidden corners, mounting-plate holes decide module alignment, and bushings guide the motion with stable clearance. Volume is low but every unit must match.

Our approach

Frames use 6063 profiles with corner brackets and socket screws so no thread is exposed to dust, and profile ends are capped to avoid traps. Mounting plates are machined from module datums with one fixture per batch. Turned bushings are grouped by fit size and assembled within a group. Clear anodizing rather than dye keeps cleaning visible.

Delivery and inspection

First batch for 15 units with hole-position and bushing fit records; frames packed in sections for on-site assembly.

Project summary

Modules aligned on first assembly, frames clean easily with no exposed threads, and grouped bushings gave stable guide clearance. Later models reuse the same machining.
