KYOTO PLATEC

What KYOTO PLATEC does

KYOTO PLATEC (株式会社京都プラテック) is a privately held Japanese contract manufacturer founded in 1982, headquartered in Kumiyama Town, Kyoto Prefecture. The company operates an integrated one-stop manufacturing system spanning seven functional departments — design (3D CAD, mechanism/circuit/PCB design), mold fabrication, injection molding (18t-650t presses, including 2-color and insert molding), plastic secondary processing (painting, silk/pad printing, hot stamping, laser marking, IMD), PCB assembly (SMT/DIP), and finished product assembly including cleanroom operations. This vertical integration is the foundation of its value proposition for customers seeking single-vendor accountability from prototype through mass production.

The company serves seven end-market verticals: automotive (battery module holders, ECU cases, DC-DC converter bases, EV high-voltage service plugs, IATF 16949 / ISO/TS 16949 certified), home appliances and OA equipment (intercoms, beauty devices, washing machine filters, remote controls), medical devices (blood glucose meters, nasal aspirators, ISO 13485 with Japanese medical device manufacturing registration), amusement equipment, LED lighting, industrial equipment, and self-developed sensor products. Named customers include Pigeon Co., Ltd. for medical devices; other customers are anonymous major Japanese automotive OEMs and home appliance manufacturers. Revenue is generated through OEM/EMS/ODM contracts, with pricing based on product specification, tooling, volume, and complexity under a quotation-based B2B model.

KYOTO PLATEC operates a multi-country production network through wholly-owned subsidiaries: K-TECH Industrial in Dongguan, China (~905 employees, since 1995); Thailand (Rayong, ~200 employees, since 2010); Mexico (Silao, since 2017); and Hong Kong (procurement and trade coordination). Total global headcount is approximately 1,300-1,400 across all sites. The company is founder-led by Representative Director Ide Toshiaki, with no external equity investors, no public listing, and no disclosed revenue. Forward signals include continued investment in Mexico for North American automotive nearshoring and a new headquarters building scheduled for 2028 completion.
