Corporate Philosophy

  1. We will deliver high-quality products unrivaled by any other company to customers on exact delivery dates. Thereby increasing the customers’ satisfaction to the utmost limit. As a result, we will acquire an overwhelming market share.
  2. We will shift the emphasis to enhancing the plant and equipment and reinvestment in excellent human resources by utilizing the profits earned. This should lead to further growth. We will contribute profits earned in Thailand back to Thailand as much as possible.
  3. We will maintain good relationships with the local community. We have actively promoted CS and will focus even more on contributing to local activities in which all the employees participate. We will reduce the noise and wastewater levels and improve the plant’s aesthetics to even higher standards.
  4. We will further improve the treatment of the employees. There is no growth potential for a company where the employees do not feel happy. However, the company’s demands against its employees will also increase in such cases. We will treat the employees who achieve good results appropriately. Furthermore, we will enhance the current high level of employee benefits.

CSR initiatives

Our philosophy is “to continue to be a trusted company in Thailand and to work to live up to that trust.” We will continue to support the development of Thailand and environmental protection through the concerted efforts of all our employees, including those in our home province of Pathum Thani.
