leadership works on the system "

trust through experience




Siam Castech always tries harder to be a leader in steel casting industry. Not only the system we underlined, but also the people that we lay emphasis on continuous improvement.

On November, 2015, Siam Castech successfully completed the audit to the quality management system, ISO9001:2008 certified by Tuv Nord (Thailand) Ltd.

Earlier, 2015, we had a great opportunity to join the most famous government support scheme called “Manufacturing Development to Improve Competitiveness Program – MDICP” by the department of Industrial Promotion, Ministry of industry Thailand. This project focused on fundamental aspects (system, production, people etc.) which really enhance our organization as a whole.

Wantana Group has been honoured to become a committee of “The Federation of Thai Industries - Foundry industry”, promising that we will maintain and protect the interests and stability of the industry to be competitive and sustainable, and leverage Thai foundry to meet international standards.
