Dimensional Checking Fixtures Specialists

Front bumper assembly

Bumper checking fixtures requirements can be very variable: from CMM fixtures fastening the part only by its RPS (fixation points), to cubing checking fixtures, simulating the part vehicle environment and controlling its deformation by Go/No Go gauges and dial indicator.

Spoiler

Checking spoilers is very complex: these parts are highly deformable and composed of a huge number of clips, cross-shaped pins and fixation holes. Consequently, to produce a spoiler checking fixture that will be able to control properly this part, we must take into account all its specificities when designing, manufacturing and adjusting it.

Exhaust line

As any part made of welded and bent components, it is essential to control the following features on exhaust line assemblies: position of the components welded to the main structure, location of holes, deformation of critical areas and position of bent sections. All these controls can be done either by Go/No Go or by dial indicator.

Scuttle grille

Scuttle grilles may consist of a single part assembly, or of two non-symetrical parts. Checking fixtures for scuttle grilles may control the fixations of the part, their fitting in the car environment and their fitting against the windshield.

Wheel arch

Most of the car parts are controlled in their vehicle position. Yet, we usually recommend to control wheel arches upside down, thus making sure that they will not be deformed during their control.

Lateral grille

As lateral grilles only have an ornamental function on the front panel, their shape can vary strongly from one version of car to the other. This also means that their specificities and fixations will also be affected by their aesthetic design. All these considerations must be taken into account when producing checking fixtures for lateral grilles.

Catalytic converter

As for any part composed of welded components, it is important to control the position of all the holes and components forming the catalytic converter. We can propose you a wide range of solutions, from checking fixtures with simple Go/No Go controls, to automated checking fixtures connected to a data acquisition system and enabling to measure 100% of the production.
