History and Relationship with the Automotive Industry

 

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.
