Mechanical sub-assembly integration

Industrial performance through precision assembly

Calip Group, an expert in high-precision mechanical assembly, supports its clients in delivering technical sub-assemblies ready to integrate into complex systems.


With advanced integration expertise, full production chain know-how, and an agile organisation based on lean manufacturing principles, we guarantee reliable, traceable solutions that meet the most stringent industrial requirements. 

Custom mechanical integration solutions

We integrate and assemble components from machining, sheet metal, aluminium profiles, technical plastics and electronics.


Our teams are involved from the design stage to develop tailor-made integration solutions, all the way through to the delivery of complete assemblies ready to be integrated into our clients’ systems.

We master a wide range of industrial assembly processes:

  • screwing
  • crimping
  • bonding
  • adhesive tape assembly
  • shrink-fitting (with oven or liquid nitrogen)


Integration also relies on a robotic adhesive dispensing system, ensuring precise, repeatable applications within tight tolerances.

Cleanroom integration for sensitive parts

Calip Group operates a 250 m² cleanroom specifically designed for the integration of sensitive or high-value mechanical sub-assemblies, including for cleanroom-grade applications.

This controlled atmosphere environment meets the requirements of the aerospace, defense, nuclear, robotics and medical sectors, with a rigorously organised lean workflow and separated entry/exit circuits to ensure full traceability, efficiency and quality compliance.

Our in-house design office and prototyping workshops provide agile, responsive support, particularly for small or medium production runs involving complex projects.

Full integration through to industrialisation

Integration and assembly are just one part of a fully controlled production chain at Calip Group. From complex part machining and surface treatment to painting, dimensional inspection and logistics, we ensure a coherent, end-to-end industrial approach.

Thanks to integrated project management, we oversee every step while optimising lead times, costs and quality. Our scope includes:

  • component sourcing
  • final assembly
  • logistics
  • dimensional quality control

Operating in critical sectors such as aerospace, defense, robotics and medical, we provide agile and reliable support from design to industrialisation.
