Manufacturing Vision & Scale
Leading Heat Sink Manufacturer with Vertically Integrated Production
Operating a 30,000㎡ state-of-the-art facility, Lineng Tech provides a complete manufacturing ecosystem. As a professional Heat Sink Manufacturer, we ensure every process—from raw material extrusion to final assembly—meets the most stringent global industrial standards
R&D & Thermal Simulation
The Foundation of a Top Heat Sink Manufacturer
Our R&D team consists of 30+ senior thermal engineers. Before mass production, we conduct rigorous CFD (Computational Fluid Dynamics) analysis using Flotherm and Icepak. This simulation-driven approach allows us to optimize fin density, airflow, and liquid velocity, significantly reducing the “Time-to-Market” for our clients’ most complex thermal challenges.
