What Stiplast does

Stiplast is a French family-owned contract manufacturer specializing in custom plastic injection molding, founded in 1986 and operating from a 5,000+ m² production facility in Halluin, Nord department, near Lille. The company serves B2B industrial clients with end-to-end services spanning 3D plan analysis and feasibility studies, mold tooling coordination through a partner network, in-house 3D prototyping, plastic injection production across small and large series, finishing (screen printing, hot stamping), and logistics delivery. Its technical platform is anchored by 14 injection presses ranging from 50 to 650 tonnes - including Sumitomo-Demag Intellect 2 electric presses and Sepro S5-25 robots for automated extraction - supported by 5 networked PC workstations for production management (GPAO) and expertise across PP, PE, PS, ABS, Nylon (PA), Polycarbonate (PC), and PMMA materials.

The company's customer base spans automotive (Fiat 500X door handles), pneumatics (Serto, Emerson/ASCO/Aventics, Airtac), industrial automation (Weforma, Coval), logistics (Stransky), biotech (porcine insemination cannula under 1 gram), cosmetics packaging (clipable wipe dispensers), and large retail (55L hot-stamped baskets). Notable customer outcomes include reducing waste from 20% to 2% on an automotive part through design optimization. The business model is project-based, quote-driven B2B manufacturing with one-time fees per production run; pricing is not publicly disclosed and is determined by part complexity, material, and volume.

Stiplast is entirely self-financed and family-held, with no external funding rounds, parent company, or subsidiaries. The original founders (DEMANGHON, ALVAREZ, DECLERCQ) have transitioned ownership to the next generation, with DECLERCQ's shares repurchased in 2025. The company holds a MORE circular economy certification (2020) for integrating recycled plastics, operates exclusively via direct sales engagement, and is geographically concentrated in France with explicit restrictions on non-EU countries.
