Component Specifications

Definition
A precision-engineered spring or clip mechanism designed as an optional component for vial positioning nests in pharmaceutical, laboratory, or industrial automation equipment. It provides adjustable retention force to prevent vial displacement during transport, filling, capping, or inspection operations while allowing easy insertion and removal.
Working Principle
Utilizes spring tension or clip geometry to apply controlled radial or axial force against vials, creating friction-based retention without damaging container surfaces. The mechanism typically operates through elastic deformation of spring steel or plastic, with force calibrated to maintain vial position during machine vibrations and movements.
Materials
Spring steel (AISI 302/304 stainless steel), beryllium copper, or engineering plastics (PEEK, Delrin) for chemical resistance. Surface treatments: passivation for stainless steel, nickel plating for corrosion protection.
Technical Parameters
  • Cycle Life >1,000,000 cycles
  • Spring Rate 0.1-2.0 N/mm
  • Retention Force 0.5-5.0 N adjustable
  • Compression Travel 2-10 mm
  • Vial Diameter Range 10-50 mm
  • Operating Temperature -20°C to 120°C
Standards
ISO 9001, ISO 13485, DIN 2095

Frequently Asked Questions

When should I use the optional retention spring/clip?

Use when processing vials with irregular shapes, lightweight containers, or during high-speed operations where vibration may cause displacement. Also recommended for inclined conveyors or when precise positioning is critical for downstream processes.

How do I adjust the retention force?

Adjustment is typically through set screws on spring tensioners, replacement of spring elements with different spring rates, or modification of clip geometry. Always calibrate using force gauges to ensure proper retention without container deformation.

Can I contact factories directly?

Yes, each factory profile provides direct contact information.
