What THY Hong Yang Precision Industry Co., Ltd. does

THY Hong Yang Precision Industry Co., Ltd., operating as THY Precision, is a Taiwan-based privately held contract development and manufacturing organization (CDMO) specializing in precision plastic injection molding for medical devices, optical components, and microelectronics. Founded in 1985, the company operates from a single integrated facility in Erlin Township, Changhua County, Taiwan, and holds ISO 13485 (medical device QMS), ISO 9001 (general QMS), and ISO 14644-1 (cleanroom) certifications. Its primary customer segment is medical device OEMs manufacturing Class I, II, and III devices, with secondary exposure to optics manufacturers (silicone hydrogel contact lenses, dental optical devices) and microelectronics producers.

The company's technology stack is centered on 80+ electric injection molding machines (30–300 ton clamping force) operating in 50,000 sq.ft ISO 8 and 5,000 sq.ft ISO 7 cleanrooms, achieving injection tolerances of ±0.0001 mm and production rates of millions of units per month. Capabilities include micro injection molding, thin-wall molding, Liquid Silicone Rubber (LSR) molding, optical injection molding, in-house mold design and tooling, automated assembly with real-time quality monitoring, and EO/Gamma sterilization coordination. Product offerings span the full CDMO value chain: design and engineering, in-house tooling, custom plastic moldings, automated manufacturing, and cleanroom assembly and packaging. Technical differentiators include vertically integrated production (design through packaging under one roof) and direct serving of regulated Class III device production.

THY Precision operates a B2B enterprise sales model, acquiring customers through direct outreach, website quote requests, multilingual content marketing (English, German, Japanese), and SEO targeting medical device engineers and procurement teams across the US, EU, and Asia-Pacific. Revenue is generated on a project-based, custom-quote model tied to manufacturing volumes under long-term OEM/ODM contracts; pricing is not publicly disclosed and depends on design complexity, material, volume, regulatory class, and cleanroom requirements. The company is privately held with no disclosed institutional or venture capital backing, no M&A activity, no subsidiaries, and no publicly reported revenue or headcount trend.
