Parting Line Management

Request Number N378790
Need details

IncWell's partner uses thermoplastic olefins (TPO) to create various parts using injection molding. One part in particular has a design that exhibits an undercut condition with a 3-5mm high standing rib along the length of the part. This rib does not allow for a hidden parting line (where the two halves of the mold meet) and results in flash on the Class A surface.  IncWell's partner seeks tooling (to prevent the generation of this flash) or post-processing technologies to reduce the amount of time needed to effectively remove this flash so that the surface is ready for the painting process. 




Following the removal of the piece from the mold, it is first inspected, any excess is removed by sanding, the surface is primed and then painted. In order to improve production efficiency, IncWell's partner is seeking to reduce the amount of post-mold processing needed for each part.


As the customer has selected the thermoplastic olefin in use, IncWell's partner is unable to select a molding material less prone to parting line generation. Additional, it is possible to create an exposed parting line, however this would, in turn, create quality issues when applying paint to the part.




Key Success Criteria

IncWell's partner sees two potential routes to a viable solution:


Tooling Solutions:

  • No visible parting line on part surface requiring post-processing
  • Required no secondary operations that would increase cycle
  • Completed within 60 sec cycle time
  • Complete in single pass through the paint process




Post – Processing Solutions:

  • Elimination of parting line in a single step
  • Result is a paintable surface not requiring further processing or special means
  • Completed within 60 sec cycle time


Possible Approaches

IncWell's partner is interested in any solutions capable of achieving the necessary processing within 60 second timeframe.


Approaches not of interest

Solution which involve secondary operations resulting in increased cycle.
