TechTrans was co-founded in April 2011 by fifteen PhD- and master's-level researchers as a specialty non-ferrous metal surface treatment company headquartered in Gyeongsan, North Gyeongsang Province, and listed on the KONEX market in July 2018.
Its core proprietary technology is the TAC (Techtrans Al-oxide Coating) process, which uses low-voltage plasma discharge to form a dense oxide film on aluminum, magnesium, and titanium substrates within five minutes—described as a world-first capability.
The process employs alkaline electrolyte formulations that exclude the six major environmentally hazardous substances, and has earned RoHS certification and an 'Excellent Green Biz A' rating, establishing meaningful regulatory compliance competitiveness.
The business model consists of three pillars: (1) TAC-based surface treatment processing and component supply, (2) design and sale of dedicated low-voltage plasma TAC equipment, and (3) supply of eco-friendly electrolyte solutions—with the equipment-plus-electrolyte model designed to generate recurring revenue streams.
Key customers include Hwashin, HL Mando, Ceragem, and Samsung Electronics, with technical sales targeting automotive parts, defense, health appliances, and IT/mobile end markets.
The company is expanding into high-value applications such as EV battery case insulation enhancement, defense robotic arm components for HL Mando, and biomedical titanium alloy surface treatment.
Its vertically integrated model spanning equipment, processing, and electrolyte supply seeks to differentiate TechTrans from simple subcontract processors, though the multi-tier subcontracting structure of Korea's foundational manufacturing sector structurally constrains pricing power and margins.
A third-party rights offering in 2023 reflects ongoing reliance on external capital, and while a long-term goal of transferring to KOSDAQ has been publicly stated, the current financial situation renders that pathway highly uncertain.
