ABOUT POLYSHINEHK
About Polyshine
Founded in 1998, Polyshine Holdings Limited established its principal manufacturing base in Dongguan in 1999. We focus on precision electronic components, connecting product development and tooling with volume production.
Engineering attention to every detail
Polyshine Holdings Limited was founded in 1998. The following year, we invested in Favor Electronics (Dongguan) Co., Ltd. in Dongguan, China, establishing our principal manufacturing base. PolyshineHK is the name used on this site to make our product families and ordering specifications easier to explore.
Our work spans the development and manufacture of electronic components for a range of industrial control and consumer-electronics applications. To us, a component is more than a part number: well-defined specifications, consistent processes and constructive technical dialogue all matter to a successful project.
From early product selection through P/N confirmation, sampling and production planning, we aim to make complex options easier to understand. If a standard specification does not fit your application, our team can discuss customization and assess what is feasible for your project.
