Molded Components for Modern Mobility Systems
Plastiques Gagnon develops injection-molded components for road vehicle manufacturers, electrification platforms, thermal systems, interior modules, and mechanical subassemblies.
Our solutions meet the precision, reliability, and performance requirements specific to transportation and automotive applications.





For several decades, Plastiques Gagnon has supported the automotive and transportation industries in the development and manufacturing of injection-molded components meeting high technical requirements.
Our expertise has been built over time through close collaboration with manufacturers and OEMs seeking reliability, repeatability, and strong industrial control.
Over the years, we have developed components for critical and functional systems: thermal modules, reservoirs, technical housings, parts integrating metal inserts, as well as visible components requiring a high level of aesthetic control.
This diversity of components has enabled us to master the mechanical, thermal, chemical, and visual constraints specific to automotive environments.
The evolution of mobility platforms—electrification, electronic integration, lightweighting, and sub-system optimization—has strengthened our role as a technical partner rather than simply a supplier.
We are involved from the early stages to optimize part design, material selection, and injection processes, ensuring stable industrialization and compliance with industry standards.
Our components are found in:
Our two facilities — Saint-Jean-Port-Joli and Levis — include:
This infrastructure enables:
Our robotic cells ensure:
The repeatability achieved fully meets the requirements of the transportation and mobility sectors.
Our quality system includes:
These processes ensure continuous technical consistency, essential for modern mobility programs.
