A Leader in Production
STM clearly understands that to produce the highest quality engines, we must have the finest production facilities. This is why both plants have been installed with the most advanced machinery. Furthermore, we are afforded the full cooperation of our parent companies in Thailand and Japan who assist us by providing the latest breakthroughs in technology and methods to keep our manufacturing and products at the industry forefront.
Layout of the factory is based on the idea of a "Smooth Flow" and production system is designed to maintain the most efficient movement of materials to the production and assembly processes. Attention is also paid to providing the most comfortable working environment so operators can work with least amount of strain.
At all time, attention is still focused on producing the highest quality products efficiently. In our factory, the basis is TPS (to eliminate "muda") with the idea of "High quality" is built-in and ensured in each process. In 1994, the company introduced "Total Quality Management" for further upgrading of all employees and development of even more effective management.
Quality For A Better World
The highest quality production will produce the highest quality products. By continually introducing the latest innovations in technology and methods, manufacturing and assembly can be constantly upgraded so that STM can produce still finer, top standard engines and at increased capacity to meet growing market demands.
