Synoxis

What Synoxis does

Synoxis is a French industrial subcontractor specializing in custom plastic material transformation, founded in 1981 and headquartered in Le Cellier, Loire-Atlantique (near Nantes). The company operates as a SAS (Société par Actions Simplifiée) with 25 employees and is structured around six in-house production capabilities: CNC machining (including large-format work up to 7,100 x 2,100 mm), thermoforming and blowing, hot and cold bending, plastic welding and bonding (solvent, UV, ultrasonic, hot air), surface finishing (deburring, polishing, laser engraving, screen printing), and complex multi-material assembly. It works from semi-finished plastic products (plates, tubes, rods) in materials such as PMMA, PVC, PE, PEHD, PP, PC, ABS, PET/PETG, and Dibond, and offers expertise in recycled, recyclable, biodegradable, and biobased plastics.

The company serves enterprise B2B clients through a direct, consultative sales model — business developers (chargés d'affaires) engage with customers from material selection through final quality control. Customers span at least six verticals: nautical (Beneteau), research (IMV), appliances (Electrolux), urban mobility (Bluebus), vehicles (Gruau), healthcare (BioMérieux), security (Idemia), and urban furniture (Jolas Agorespace). Pricing is project-based and quote-driven, with no recurring contracts disclosed; production ranges from single prototypes to small, medium, and large series.

Commercially, Synoxis positions itself as a local Loire-Atlantique partner with nationwide French delivery, supported by a website portfolio, LinkedIn presence, and direct contact funnels. The company has received EcoVadis 2026 RSE certification, reflecting an explicit focus on environmental and social responsibility. Its competitive positioning rests on offering comprehensive multi-process plastic transformation under one roof, large-format machining capacity that exceeds typical regional subcontractor limits, proprietary nesting optimization software to reduce waste, and a 43-year track record with enterprise customers across diverse industries.

Core offering

Synoxis is an industrial subcontractor that transforms semi-finished plastic materials (sheets, tubes, rods in PMMA, PVC, PE, PEHD, PP, PC, ABS, PET/PETG, and Dibond) into custom finished or semi-finished parts. The company provides six integrated capabilities under one roof: CNC machining, thermoforming and blowing, hot and cold bending, gluing and welding, surface finishing, and complex assembly, serving industrial clients from prototypes through large series.

Product overview

Synoxis is a plastic transformation company (plasturgiste) offering custom manufacturing services since 1982. Their core service portfolio includes six main production capabilities: Usinage (CNC machining), Formage et Soufflage (forming and blowing), Pliage (bending), Collage et Soudure (gluing and welding), Finition (finishing), and Assemblage (assembly). These services work together to transform semi-finished plastic materials (sheets, tubes, rods) into finished or semi-finished parts. The company machines materials including PMMA, PVC, PE, PEHD, PP, PC, ABS, PET/PETG, and Dibond, serving industries such as nautical, research, urban furniture, industry, security, and fitting. Delivery is available throughout France with quality control at each production stage.

Functional benefit

Products and services

• Usinage (CNC Machining) CNC machining of plastic materials including cutting, drilling, milling, and engraving for small, medium, and large series as well as prototyping. Capabilities include machining of large dimensions up to 7 meters with multiple machining centers and a laser machining center, intended for industrial clients needing custom plastic parts.
• Formage et Soufflage (Forming and Blowing) Hot forming and blowing of plastic materials to create custom shapes, hollow or domed parts. Forming uses heated plastic plates molded on tools; blowing uses air injection to create hollow or domed shapes including custom plastic bubbles, for industrial clients needing bespoke plastic geometries.
• Pliage (Bending) Hot and cold bending of plastic sheets to create precise angles and shapes such as covers, housings, or display stands. Equipment supports large-format bending up to 3 meters with 45mm radius and 25mm thickness, for industrial customers requiring formed plastic components.
• Collage et Soudure (Gluing and Welding) Gluing and welding of plastic parts using multiple techniques: solvent bonding (PMMA, PVC, ABS, PS), two-component bonding, UV bonding, hot air welding, mirror polyfusion, and ultrasonic welding. Equipment includes 3-meter polyfuse, tube polyfuse, UV bonding benches, extruders, and torches, intended for industrial assembly of plastic components.
• Finition (Finishing) Surface finishing services including manual and mechanical deburring, polishing (glossy, satin, or matte finishes), laser engraving, screen printing, and tampography for applications in design, architecture, industry, and medical sectors.
• Assemblage et ensembles complexes (Assembly) Assembly of simple or complex plastic parts including multi-material assemblies with wiring, electrification, screen mounting, and other equipment. Includes mounting of accessories (hinges, handles, inserts, rivets, screws) and complementary component bonding (films, supports, seals), for industrial customers needing integrated plastic sub-assemblies.
• Matières plastiques (Semi-finished plastic materials) Supply and transformation of semi-finished plastic products (sheets, tubes, and rods) in various materials including PMMA, PVC, PE, PEHD, PP, PC, ABS, PET/PETG, and Dibond, providing the raw substrate for the company's custom manufacturing services.
