2K Tail Lamp Tooling | Clean Interface Lines | Jeancen Mold

Multi-shot tooling for lens + frame structures—engineered to control interface flash, alignment drift, and cosmetic consistency.

Clean interface lines, stable alignment, and repeatable cosmetic output.

Automotive lighting 2K parts often combine a lens zone and a structural/cosmetic frame. The highest risks are interface flash, alignment drift, and visible defects on the cosmetic side.
We engineer tooling around shut-off integrity, indexing accuracy, and thermal balance—so the interface stays clean, and the part remains consistent across production.


Engineering Controls

  • Stable indexing/positioning to protect shot-to-shot alignment
  • Shut-off design for clean interface boundaries (flash control)
  • Venting logic to avoid burn marks without interface leakage
  • Warpage control to maintain fit and assembly stability


What We Need

  • CAD + interface definition between shot 1 and shot 2
  • Material pair + color requirement
  • Cosmetic side definition + appearance target
  • CTQ list (alignment, fit, sealing, assembly constraints)


Next Step

Send CAD and CTQ notes. We’ll reply with a focused DFM and a practical tooling plan for stable 2K production.
