Use Case: Automotive Power Heavy Duty 60kW Hydrogen Fuel Cell Modules
Client: OEM manufacturer of Automotive Zero-Emission Fuel cells.
Solution: Spring-Fast SL Series

  • The solution had to protect the wiring from abrasion and scuffing.
  • The grommets had to be vibration/heat resistant with a UL-94V-0 rating
  • Tight engine compartments made glued in grommets very difficult to apply/reapply.
  • Nylon or PE grommets with glue or PSA failed in normal operations testing – leading to lower quality & rework
  • Thermoplastic nylon or polyethylene can flow/deform/melt as temperature rises.

SOLUTION:  Replace the PE/nylon with Spring-Fast SL grommet edging
  1. Fast easy application with simple finger pressure without adhesives provided the needed wire protection.
  2. The TPE encapsulation of the stainless steel substrate is flexible, resists deformation, and protects wiring from damage caused by abrasion.
  3. Qualified for vibration Mil-Std-810C, Flammability UL94 V0
  4. Strong edge retention – tested to aerospace standards to rms G 41.7 for mechanical shock and vibration.
Why it works so well

Spring-Fast grommet edging has a steel substrate and most series are fully encapsulated in flexible TPE for superior abrasion protection, chemical resistance, and 4-axis flexibility.  The steel core has castles, or gripping teeth, that angle into the metal edge creating a gripping force and powerful edge retention without adhesives.
