SUB-ALLIANCE

What SUB-ALLIANCE does

SUB-ALLIANCE is a privately held Belgian industrial manufacturing alliance headquartered in Mouscron, Belgium, that consolidates four specialty manufacturing divisions under a single brand to deliver advanced technical parts in polymers, composites, metals, and transmission elements. The alliance comprises FERONYL (injection moulding of polymers, composites, and multi-materials), GRIMONPREZ GEARS & GEARBOXES (engineering and manufacture of gears, transmission parts and gearboxes in small and medium series), DEDECKER PRECISION MECHANICS (bar turning, milling, grinding, honing, heat treatment, super finishing), and TECNOLON WORKS (tooling for the plastics industry and machining of technical parts in plastic, polymer, metal, copper, brass, aluminium, and titanium). Operations span six production sites in Belgium, with the alliance formed in 2012 atop the legacy operations of the four divisions, which collectively claim 75 years of combined manufacturing expertise.

The company operates a B2B custom manufacturing model, executing projects from research and prototyping through full-scale production, surface treatment, assembly, and packaging for enterprise customers across eight regulated verticals: aerospace, defense, medical, bank, energy, filtration, civil engineering, and transport and engineering. Quality positioning is anchored by ISO9001 and EN9100 certifications, the latter enabling aerospace and defense supply. GTM is enterprise field sales with quote-based, project-driven pricing, supported by a multilingual corporate website (English, French, Dutch), direct phone/email contact, and a newsletter channel. The flagship demonstrator project, the ATOM 9 pneumatic differential developed with D&G Tuning, illustrates full-lifecycle capability including chrome plating, heat treatment, and tight-tolerance machining.

The firm is privately held with no disclosed external investors, funding rounds, or M&A activity. Headcount is reported at 11–50 employees and revenue is not publicly disclosed. No AI/ML capabilities, patents, or third-party technology integrations are evidenced in the input data, positioning SUB-ALLIANCE as a traditional precision contract manufacturer whose competitive proposition rests on certified quality, integrated multi-discipline capacity, and process know-how rather than software-enabled differentiation.
