Company History
1996
Relocated to Taichung Industrial Park
Driven by strong demand and the desire to expand into larger markets, we chose to set up a factory in the Taichung Industrial Park. The following year, we purchased injection molding machines and expanded our scale to establish a Plastic Molding Department. By learning plastic injection, we continuously refined our mold manufacturing capabilities and began delivering small-batch production orders.
2005
Established Plant II
With the continuous growth and expansion of the Injection Molding Department, we established Plant II on 38th Road in the industrial park to serve a more diverse customer base and meet greater demands. The Injection Molding Department was relocated to Plant II. In 2006, we completed our corporate identity (CI) and purchased more injection molding machines to embrace future challenges.
2009
Obtained ISO 9001 Third-Party Certification
Progress never stops. In 2009, to promote large-scale corporate development, we successfully passed the ISO 9001 third-party certification, laying the foundation for future quality and efficiency through standardized management.
2021
Obtained Medical Device Manufacturing License
Facing environmental challenges, the company resolutely stepped into the medical device field in 2015 for a strategic transformation. In 2021, by virtue of our outstanding capabilities, we were awarded a manufacturing license by the Ministry of Health and Welfare, achieving an important milestone in our transformation.
2023
Obtained ISO 13485 Third-Party Certification
Continuing the transformation blueprint initiated in 2015, we successfully achieved ISO 13485 third-party certification in 2023. We comprehensively perfected our medical quality management system, deepened our roots in the medical device manufacturing sector, and built a solid industry moat.
2026
Implemented Medical Device Quality Management System (QMS)
In 2025, we launched a branding strategy centered on swallowing care, moving towards brand management in 2026. We ventured into the swallowing care market, implemented the QMS management system, successfully launched our proprietary self-developed products, and completed the layout of our medical device industry chain.
Present
Looking Forward and Going Global
Looking ahead to the global market to continue our chapter of growth. The company will leverage its profound technological background to continuously introduce high-quality medical products, fulfill corporate responsibility through innovation, and co-create a healthy and sustainable social environment.
