What Coniex does

Coniex S.A. is a privately held Spanish industrial company founded in 1985 and headquartered in Palau-Solità i Plegamans (Barcelona region), operating for approximately 39 years in surface treatment and centrifugal casting technology. The company supplies industrial manufacturers with a vertically integrated portfolio organized across five product families: surface treatment equipment (vibratory finishing, sandblasting, shot blasting, washing/degreasing, wastewater treatment centrifuges rated at up to 300 liters/hour, and chip treatment systems) plus associated abrasive consumables; centrifugal casting systems including proprietary silicone and rubber molds (SILCODISC, ZAMAKDISC, CASTEX), pewter and zamak alloys meeting DIN 1774, and the C3S PRO automated casting machine with robotic metal feeding and PLC Siemens control capable of up to 6 casts per minute; epoxy enamel systems under the ESMALTEX brand offering BPA-free, two-component formulations in over 60 colors with Ultra Glass and DOMINGFLEX variants; technical silicone and masterbatch products under EVC and SILCOLORS for demanding applications including medical, food-contact, and military; and laboratory presses from 22 to 100 tons with optional Industry 4.0/5.0 connectivity.

The company serves four primary customer verticals: jewelry, costume jewelry, and fashion accessories (the explicitly flagged primary segment); industrial manufacturing including automotive, aerospace, energy, and polymer-chemical components; enameling and coating applications for buttons, badges, and promotional items; and additive manufacturing post-processing through the ABRAST alliance. Go-to-market is direct technical-consulting sales to enterprise industrial buyers, with engineering advisory, laboratory testing, maintenance, and the Coniex Academy training program functioning as both service revenue streams and customer lock-in mechanisms. Pricing is quote-based with no publicly disclosed price lists. Distribution is direct with wholly-owned subsidiaries in Mexico and Portugal supplementing the Iberian headquarters.

Coniex's commercial differentiation rests on proprietary in-house chemical formulations, branded equipment IP, regulatory documentation for regulated end-markets (BPA-free, FDA, REACH, RoHS, EN71-3, military specs), and strategic ecosystem positioning as a founding member of IAM3DHUB alongside HP, BASF, Materialise, and Leitat in the Barcelona additive manufacturing cluster. Revenue, funding, and detailed financial metrics are not publicly disclosed.
