Graindorge Traitement de surfaces

What Graindorge Traitement de surfaces does

Graindorge Traitement de surfaces is a French industrial subcontractor founded in 1928 by Louis Graindorge and headquartered in Sens, Bourgogne-Franche-Comté, approximately 100 km from Paris. The company operates a ~10,000 m² single-site production facility described as a unique flagship in Europe, employing 14 people and running 16 automated production lines with daily capacity of 2,000 m² of treated surface and 150,000–250,000 pieces. Its core activity is electrolytic surface treatment (galvanoplasty) — the electrodeposition of metal coatings including Chrome III, Nickel, Bronze White and various Gold (2N, Champagne, Rose) finishes onto plastic (~90% of treated materials) and metal parts (brass, zamak) for the luxury cosmetics, perfume and spirits packaging industry.

Graindorge's technology combines decades-old chemical expertise with selective robotic automation. Since 2009 the firm has been a sector pioneer in robotization, and through its partnership with SILEANE it has deployed adaptive robots for depalletizing and handling on galvanization lines. Quality control is described as substantially manual, with expert operators handling sorting, fixture mounting, bath-sampling and final inspection. The company emphasizes rare-in-Europe chemical-substitution programs aligned with tightening plating-chemical regulation, and positions "Made in France" craftsmanship as part of its value proposition.

The business model is contract-based B2B enterprise sales to luxury houses. Graindorge sells custom electrolytic finishing services rather than licensed products; pricing is quote-based on volume, complexity and metal type and is not publicly disclosed. End customers include Hermès, Dior, Montblanc, Paco Rabanne, Calvin Klein, Amouage, Cacharel, Katy Perry and Courvoisier. Since 2022 the firm has been a wholly-owned subsidiary of ÉPHIE Industries, a French industrial group founded by Patrick Chouvet that also owns EAC (metal ornaments) and Bouvier (high-end signage), positioning Graindorge within a roll-up targeting the luxury-goods supply chain.
