Component Specifications

Definition
A precisely machined cavity or bore within a vial positioning nest, designed to securely hold and align vials during automated filling, capping, labeling, or inspection processes. This component ensures consistent positioning to maintain process accuracy, prevent vial tipping, and enable reliable robotic handling in high-speed production lines.
Working Principle
The cavity/bore provides geometric constraint through its internal dimensions and surface features, using friction, mechanical interference, or vacuum assistance to hold vials in precise alignment. It interfaces with vial geometry to maintain consistent orientation relative to processing equipment, ensuring repeatable positioning for downstream operations.
Materials
Stainless steel (AISI 316L, 17-4PH), aluminum alloys (6061-T6, 7075), engineered plastics (PEEK, UHMW-PE), or ceramic (alumina, zirconia) depending on application requirements for corrosion resistance, wear resistance, and cleanability.
Technical Parameters
  • Depth 15-50 mm
  • Hardness HRC 40-60 (metal), Rockwell M70-90 (plastic)
  • Cleanability Autoclavable/Sterilizable
  • Bore Diameter 8-30 mm (adjustable based on vial size)
  • Surface Finish Ra ≤ 0.8 μm (for metal), Ra ≤ 1.6 μm (for plastic)

Frequently Asked Questions

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.

Can I contact factories directly?

Yes, each factory profile provides direct contact information.
