PROFIT DAY's Origins
Profit day Holding Limited was established in 1995, and the Dong Fu factory began production in 1996. From the outset, PROFIT DAY has built close, long-term relationships with Japanese customers, accumulating manufacturing experience through ongoing communication, technical exchange and continuous quality improvement.

Long-Term Partnership Through Continuous Improvement
We believe long-term cooperation depends on more than product delivery — it comes from stable management, continuous quality improvement and a deep understanding of customer requirements. Over many years, PROFIT DAY has continued to refine production and quality management to meet our customers' practical expectations.

A Dynamic Balance of Quality, Cost and Delivery
PROFIT DAY's operating philosophy is to achieve a practical, sustained balance between quality, cost and lead time. Our goal is not merely to fulfil orders, but to build lasting win-win-win relationships among customers, end users and PROFIT DAY.

A More Stable, More Sustainable Production Model
In line with developments in China's labour and environmental policies, PROFIT DAY continues to improve production processes and pursue safer, more stable and more sustainable manufacturing. Technical support and professional expertise from long-term customers also drive ongoing improvements at the Dong Fu factory.

A Complete and Coordinated Supply Chain
In supplier selection, PROFIT DAY values quality consistency, delivery capability and the foundation for long-term partnership. Many core suppliers have been verified or approved by customers. Through close collaboration among suppliers, production teams and customers, we have built a supply chain with greater flexibility and responsiveness.

From the Japanese Market to New Possibilities
Since 2014, the Dong Fu factory has expanded domestic purchasing and sales in China, bringing PROFIT DAY greater flexibility and new opportunities for growth. While we value our long-term partnerships with Japanese customers, we also welcome reliable, practical and sustainable cooperation with new customers worldwide.
