Functionally integrated parts (FIP)

LiteWWeight® Pin connection geometry can be integrated into the injection molded part, which simplifies production, reduces costs and enables complete design freedom.

Pin functional integration

Advantages of FIP:

  • Reduced cycle time
  • Reduced costs due to the fast process and less parts to manipulate
  • Higher Strength: With less material, higher strength can be achieved
  • Easy one-sided access only assembly process # Geometric Simplification
  • Connection geometry can be integrated into the part to connect
  • Form freedom: No rotational symmetry required
  • Improved aesthetics: No fasteners are visible
