Dongguan Yyi Technology Co., Ltd. Company Profile

At the core of YYI Tech’s operations lies a fully integrated production line designed for speed, precision, and scalability. Their self‑owned factory is outfitted with over 300 sets of advanced equipment, including 220 plastic 3D printers (SLS, SLA, MJF, FDM, PolyJet), 10 metal SLM printers, 50 injection‑molding machines, and 40 CNC machining centers, all supported by dedicated post‑processing and quality‑inspection departments. This multi‑modal setup allows seamless transitions from rapid prototyping to small‑batch production, ensuring that parts can move swiftly through additive manufacturing, tooling, molding, machining, finishing, and inspection without ever leaving the premises. Since earning ISO 9001:2015 certification in 2019, YYI Tech has refined its workflows to embrace lean principles, minimizing lead times (some parts in as fast as one day) and maintaining tight tolerances across a broad spectrum of plastics and metals

YYI Tech offers both Original Design Manufacturing (ODM) and Original Equipment Manufacturing (OEM) services, accommodating projects ranging from concept sketches to turnkey production. In an OEM capacity, they produce customer‑provided designs and specifications, handling everything from mold fabrication and injection molding to final assembly and packaging. As an ODM partner, their in‑house engineering team collaborates from the ground up—developing 3D CAD models, optimizing designs for manufacturability, selecting materials, and iterating prototypes until the product is market‑ready. Their one‑stop approach means clients can consolidate multiple vendors into a single point of contact, reducing overhead and accelerating time‑to‑market without compromising on confidentiality—YYI Tech will even sign NDAs to protect proprietary IP

Backed by a 20‑plus member engineering department with two decades of industry experience, YYI Tech’s R&D capabilities stand out for their depth and versatility. The team employs a suite of software tools (CAD, CAM, FEA) to conduct structural simulations, material analyses, and process optimizations before ever touching a machine. Whether it’s developing new composite formulations for vacuum‑cast resins, refining support‑structure algorithms for metal 3D printing, or engineering custom fixtures for CNC setups, their researchers continually push the boundaries of rapid manufacturing technologies. This commitment to innovation ensures that each project benefits from the latest advancements in additive and subtractive processes, delivering parts that not only meet but often exceed performance and cost targets
