About Baoming Optical

Zhejiang Baoming Optical Materials Co., Ltd. is a PC and PMMA optical extrusion manufacturer founded in 2008. We make custom lighting profiles, LED lenses, diffusers and light covers for luminaire brands and OEM/ODM manufacturers in more than 30 countries.

Who we are

Baoming Optical was founded in 2008 in Deqing County, Huzhou, Zhejiang, and has extruded polycarbonate (PC) and PMMA optical profiles ever since. Our sections go into linear luminaires, troffers, LED strips, signage and architectural lighting – and into automotive and building products where an optical plastic part has to hold its dimension and its colour.

The company behind the profiles is Zhejiang Baoming Optical Materials Co., Ltd. We run our own tooling shop and 20+ extrusion and co-extrusion lines, so die design, trial extrusion, adjustment and volume production all happen in one place. That is what keeps development short: a new section moves from drawing to first-off part without waiting on outside suppliers.

We describe what we run. If a requirement falls outside optical extrusion – injection moulded end caps, for example – we say so early and help you source it rather than promising something we do not make.
