What HHY LTD does

HHY LTD, legally Hsin Hung Yih Technology Co., Ltd. (鑫宏益), is a privately held Taiwan-based OEM/ODM and EMS contract manufacturer founded in 1998 and headquartered at No. 9, Aly. 4, Ln. 121, Longxiao St., Guishan Dist., Taoyuan City 333031. The company operates a vertically integrated turnkey manufacturing model that delivers end-to-end product realization — from concept, engineering, and prototyping through tooling design, plastic injection molding, metal parts fabrication (CNC machining, die casting, forging, metal injection molding, powder sintering), electronic manufacturing services (SMT and THT PCB assembly, box build, cable and wire harness assembly), secondary operations (surface finishing, heat treatment, laser engraving), and final assembly, packaging, warehousing, and logistics — all under one roof. Advanced testing capabilities include AOI, ICT, X-ray inspection, FEA, CFD, and thermal analysis, supporting quality control across the production lifecycle.

The company serves two primary customer segments: (1) startups and emerging companies launching new hardware products that lack in-house manufacturing infrastructure, and (2) established brands and OEMs seeking a reliable overseas turnkey partner with IP protection and vertical integration to reduce supplier complexity. Secondary use cases span consumer electronics, automotive electronics, medical devices, telecommunications, industrial/mechanical products, and plastics manufacturing.

HHY's business model is project-based, quote-driven contract manufacturing with no publicly disclosed tiered pricing or volume data. Customer acquisition is primarily direct: inbound quote requests via the hhycorp.com website, direct phone (Taiwan +886-987-659-996; US +1-814-207-2899), WhatsApp, and email ([email protected]), augmented by content marketing through a bilingual (English/Japanese) blog and LinkedIn/Instagram presence. The company claims active partnerships across 135+ countries and regions, with named enterprise customers in the United States (California, Texas) and Australia (Melbourne), though it is privately held with no disclosed revenue, headcount, funding rounds, certifications, patents, or management team information.

Revenue model

1. OEM/ODM Contract Manufacturing: End-to-end OEM (Original Equipment Manufacturing) and ODM (Original Design Manufacturing) services covering the entire product lifecycle from concept and design to prototyping, manufacturing, assembly, quality control, packaging and logistics. Revenue is generated through manufacturing fees for custom product runs, with pricing based on project complexity, volume, and material requirements.
2. Electronic Manufacturing Services (EMS): Full spectrum electronic manufacturing services including PCB assembly (PCBA), box build assembly, cable and wire harness assembly, supply chain management, and testing services. Revenue generated through assembly fees, component procurement margins, and testing charges.
3. Plastic and Metal Parts Manufacturing: Precision manufacturing of plastic parts (injection molding, blow molding, thermoforming, rotational molding) and metal parts (CNC machining, die casting, forging, metal extrusion, MIM, powder sintering). Revenue through per-unit manufacturing charges and tooling/fixture fees.
