What Thermolympic does

Thermolympic S.L. is a privately held Spanish plastic injection molding manufacturer founded in 1991 and headquartered in Utebo, Zaragoza. The company operates a 9,000m2 production facility equipped with 35+ injection molding machines ranging from 50 to 2,700 tons of clamping force, supported by 50 robots for automated assembly and quality control, and 14 grinding mills for in-house plastic recycling processing approximately 30,000 kg of material annually. Its service portfolio includes custom plastic injection molding, 2K/bi-material injection, mold design and maintenance (preventive, corrective, and predictive), automated assembly, and the proprietary SmarTh digitalization platform for real-time monitoring, anomaly detection, and predictive maintenance.

Thermolympic serves six B2B verticals — automotive, medical, home appliances, consumer goods, construction, and lifting/elevation — through a sales-led direct engagement model with custom project quoting and a stated 24-business-hour response commitment. The company holds IATF 16949 (automotive quality), ISO 14001 (environmental management), and ECOVADIS 2025 (ESG) certifications, qualifying it as a Tier-2/3 supplier for European OEMs and medical device producers. It serves clients in Europe, primarily Spain, with no disclosed international footprint outside the region.

The business model is project-based custom manufacturing with revenue generated per production run, augmented by mold maintenance services and recycled material sales. The company has invested heavily in sustainability infrastructure (779 solar panels / 441 kWp providing 15% of electricity and reducing 52,550 kg CO2/year; up to 100% material utilization through recycling) and in next-generation materials via the Wood4Plastic biopolymer R&D consortium. Recent strategic moves include the Engel Duo 2700 acquisition, the SmarTh software platform launch co-developed with the European FACTS4WORKERS project, and an internal reporting system established under Spain's Law 2/2023 on whistleblower protection.
