Who we are

We’re a family-owned business founded by a Taiwanese entrepreneur in the 1980s. What began as a humble workshop in Taipei has grown into a trusted ODM/OEM manufacturing partner, with a solid presence in Shenzhen, Hong Kong, and Taipei.

 

Specializing in niche imaging products, we design and manufacture innovative yet affordable solutions for business clients around the world. Our mission has always been simple: to make technology accessible without compromising quality.

 

While our main production base is in Shenzhen, we also offer the option to manufacture in Taiwan for clients seeking alternative sourcing, added flexibility, or region-specific requirements.

 

In addition to our standard product lineup, we also offer custom ODM/OEM services. Get in touch—we’d love to explore how we can support your business.
