Today we provide every solution for these controls that are available:

  • Dimensional control by camera
  • Aspect control by camera
  • Dimensional control by sensor


Our metrological control equipment includes :

  • Three-dimensional measuring machine CMM
  • Roughness measurement
  • Cylindrical roundness and form defect bench (roundtest)
  • Profile control by camera
  • Profilometer
  • Traditional metrology equipment

SPC Controls

The SPC control is automated and completely integrated into the process of manufacturing.

Each machine is directly linked to the ERP with allows continual information feedback as well as the piloting of specific measurements.

We have operated at a rate of 10ppm (parts by millions) for over 10 years.

APQP Method

The APQP, or Advanced Product Quality Planning has become an essential element for the management of our projects. This structured method enables us to encompass all the actions to be performed during the phases of development and project planning in order to guarantee our customers with a perfect product. The purpose of this planning allows the project team to anticipate and avoid any errors rather than undergoing corrections during the phases of the series. All project and product data is thus planned, managed and monitored on a daily basis.

MRP software

This tool allows us to efficiently plan all the resources in the company.

It generates, among other things, an operational planning of production based on the forecast of customer requirements, and enables the regulation of material supplies according to the production progress.

As a result we can optimise our inventory level and internal resources with extreme precision.


All the criteria concerning washing and particular cleanliness are guaranteed by two very modern washing machines.

These machines provide optimal degreasing and excellent results of cleanliness. We use A3 hydrocarbon solvents and modified chlorine free alcohol to meet all the requirements of degreasing whilst respecting and protecting the environment.


We have reached an overall service level of 99% for 30 million parts delivered per year. Customer satisfaction has become our main priority.

Thanks to the use of an ERP and an efficient traceability system, DJC identifies and certifies the entire supervision of proceedings from manufacturing to the reception of materials at delivery.
