Our quality control procedures

What is the purpose of control procedures?

Our quality department ensures the control and conformity of all the parts we produce, regardless of the production process used. We have strict control procedures to ensure that the parts meet your specifications. By ensuring that your parts meet your expectations, we help you to reduce your costs by reducing the number of iterations. 

A QC environment according to an international standard

Our quality control (QC) department ensures that the standards in force are respected, for example a temperature of between 18°C and 22°C and a controlled humidity, in order to guarantee the accuracy of the dimensional measurements carried out.

Our dimensional inspections

We attach great importance to the quality and conformity of the parts we produce. This is why we have put in place a rigorous control procedure in two inspection phases:


  • During the manufacture of your parts: our CNC machines are equipped with RENISHAW probes which detect shape and dimensional errors during manufacture and thus save time and improves precision. This allows us to react more quickly to errors and to take corrective action as soon as possible in order to guarantee the quality of our parts in ever shorter time frames.


  • Before the parts are shipped: our QC department uses the latest generation of dimensional inspection machines, with for example CMMs or profile projectors. These machines are regularly serviced and calibrated to ensure that the parts meet the required specifications and quality standards.

Our latest quality generation and dimensional inspection machines:

  • CMM machine (HEXAGON Inspector Classic 08.10.06)
  • Optical projector (optique EASSON C3020)
  • Rockwell hardness tester
  • Brinell hardness tester
  • ...

Our material analyses

To guarantee the use of the requested materials, we are equipped with the latest generation of metal and plastic analysis machines.

  • We check the plastic and metal blocks when they arrive at our production site. This allows us to provide you with a certificate of material analysis when necessary.


  • This check ensures that we receive and use the correct materials ordered, giving you the assurance that the parts produced meet your requirements and that your specifications are met.

Our material analysis machines:

  • Plastic material analyzer (ThermoFisher Nicolet iS5)
  • Metal material analyzer (Spectrotest TXC35)

Our roughness and surface treatment inspections

In order to guarantee that the parts produced comply with your requirements in terms of surface quality and treatment, our quality control department focuses on:

  • The surface condition of your parts using our roughness testers (roughness meters) to ensure the required roughness (Ra) compliance


  • The thickness of surface treatments using our coating thickness testers to ensure your requirements are met


Our machinery & tools:

  • Roughness tester
  • Coating thickness tester

Our compliance guarantees

We attach great importance to the conformity of your parts and make it a point of honour to carry out rigorous checks at various stages of production. This allows us to quickly identify any non-conformities and correct them before your parts are shipped. As a result of these checks, we are able to issue certificates of conformity (CCPU 2.1; 2.2 and 3.1) for low-volume production.
