TMK has the latest technology to operate the three main lines of operation: design, assembly and maintenance. We constantly incorporate new equipment to improve our industrial park in order to better meet the needs of our customers, tackle new challenges and conquer new frontiers.

We create partnerships with several suppliers, expanding our ability to provide diversified products and striving to maintain a healthy policy with them.

We manufacture parts of different sizes and formats, using high precision machinery, through CAD applications, laser cutters and computerized bending machines.

Currently, among other services, we supply parts and carry out the assembly and maintenance of rolling stock used at the Yamanote, Keio, Tobu and Tokyu lines. It is a great pleasure to be able to participate in the expansion of an efficient and modern transportation system.

Our long experience in following up qualifies us to carry out the most different works. All this with a lot of respect for the customer and commitment to quality, these two points being the main pillars that guide the decision making in our company.
