993 center cap, AlSi10Mg F0 concept without crest

ConceptFunctional part

Independent concept of a metal center cap with four integrated tabs to screen a small LPBF series. PorscheFanatics confirms the identity and the historical PET status; partworks publishes three dimensions and states that the original is plastic.

Known limits

  • Only Ø76, Ø60, 46 mm height and plastic come from the commercial record; all interfaces are hypothetical.
  • Replacing plastic with AlSi10Mg changes mass, compliance, fatigue and corrosion; no equivalence is claimed.
  • The 0.4 mm, 0.30 coefficient, 250 km/h, 20 g and +120 K cases are synthetic.
  • The model includes no Porsche emblem, crest or design.
  • The STEP proves only a computable BREP and must not be installed on a wheel.

Post-processing it would need

  • Support removal with an open interior volume
  • Heat treatment qualified to preserve tab flexibility
  • Finishing of clip surfaces and edges
  • Anodizing after dimensional inspection
  • Front face left neutral with no Porsche marking

What a supplier would have to provide

  • Traceable powder, machine, parameters, orientation, lot and recycling
  • Bending coupon in the tab orientation
  • CT or radiographic inspection of the tab roots
  • Dimensional inspection of the ring and the four clips
  • Contracted roughness, radii, porosity and fatigue
  • Insertion, pull-out, rotation, impact and thermal cycling tests
