Taiwan-Based OEM/ODM Partner for Sensor Faucet & Flush Systems

Dear Sir or Madam,

We are Duo Liang Enterprise Co., Ltd., a Taiwan-based manufacturer specializing in sensor faucets and automatic flush systems.

For over a decade, we have focused on OEM and ODM production for international brands, with an emphasis on product consistency, supply stability, and long-term cooperation.

Taiwan has long been a trusted manufacturing base for Japanese companies, particularly in precision components and sanitary ware products.

In response to the growing importance of supply chain resilience and BCP (Business Continuity Planning), we would like to introduce Duo Liang as a potential second-source manufacturing partner based entirely in Taiwan.

Our strengths include:

• Taiwan-based manufacturing (non-China origin)

• OEM / ODM experience in sensor faucets and automatic flush systems

• Capability for small-lot prototyping and mass production

• Flexible engineering support aligned with Japanese development processes

• Strict confidentiality and quality control management

We believe that Taiwan manufacturing can complement existing supply structures by enhancing supply stability while maintaining quality standards expected by Japanese brands.

We would welcome the opportunity to introduce our products and technical capabilities in more detail, should this align with your current or future sourcing strategy.

Thank you very much for your time and consideration.

Kind regards,

Kean Tsai

Duo Liang Enterprise Co., Ltd.
