常见问题

What materials are best for positioning cavities in cleanroom environments?

Stainless steel AISI 316L and PEEK are preferred for cleanroom applications due to their corrosion resistance, low particle generation, and compatibility with sterilization processes.

How do positioning cavities maintain vial alignment during high-speed operations?

Through precise dimensional tolerances, optimized surface finishes, and sometimes vacuum assistance or spring-loaded mechanisms that provide consistent holding force while allowing quick vial insertion and removal.

Can positioning cavities be customized for different vial sizes?

Yes, they are typically designed with adjustable or interchangeable inserts to accommodate various vial diameters and shapes, minimizing changeover time between production runs.
