Trunk trim checking fixture

Trunk trim frame checking fixture

  • Aluminium founding basis
  • Positioning of the part in its car position
  • Simulation of the car environment of the part by openable clipping system and aluminium simulation blocks
  • Control of the conformity of the part by Go/No Go pin
  • Measurement of the part by CMM machine


As part of the visible components of the car, the trunk lid must be as much dimensionally as visually conform. Consequently, trunk lids checking fixtures must not only reproduce the car environment of the parts, but also be designed in a way enabling to mount, dismount and control the part without damaging it.

Materials and tolerances

Our checking fixtures are produced in aluminium, the components submitted to wear-and-tear are produced in steel. Tolerances for RPS (fixation points) and dial indicator points: ±0.05mm. Tolerances for simulation blocks: ±0.1mm.

Documentation delivered

Minimum documentation: dimensional report of your checking fixture, 2D assembly drawing, assembly CAD.  Optional documentation: R&R report, user manual, stabilization certificate.

Cycle time and traceability

The control of trunk trims for metrology analysis is traditionally done by CMM fixtures, a precise but costly and long solution. An effective and profitable alternative would be to resort to CAPTOR-R for the measurement of this kind of part: with one second per point for measurement and analysis, CAPTOR-R provides to its users a quick and reliable solution specifically adapted to the requirements of the automotive sector.
