Tianjin International Tiegong Welding Equipment Co., Ltd. is a Sino foreign joint venture established through joint investment from China, Japan, and Taiwan. After restructuring and expansion, it specializes in the development and manufacturing of automotive welding and assembly equipment, as well as intelligent equipment.
Established on November 24, 1994, the registered capital increased from 600000 US dollars to 1.5 million US dollars. In 2004, the company purchased land to build a new factory, equipped with large CNC machining equipment, testing equipment, and multiple portable three coordinate machines. The factory covers an area of 4600 square meters and has a total of 60 employees. After more than 20 years of development, Tianjin International Railway Engineering Co., Ltd. has gained full recognition from the industry for its technological level and comprehensive strength. In addition to independently undertaking various projects, Tianjin International Railway Engineering Co., Ltd. also collaborates with Japan International Railway Engineering Co., Ltd. and other partners in different combinations to undertake projects with different requirements from users. With the continuous expansion of business, new fields of tooling equipment such as intelligent equipment, engineering machinery, and agricultural machinery have been opened up, and the business volume is constantly expanding. We obtained ISO9001 (2000 version) quality system certification in November 2002 and ISO14001 environmental system certification in October 2012. In December 2015, it passed the National High tech Enterprise Certification, and in December 2022, it obtained the Tianjin Innovative Small and Medium sized Enterprise Certificate.

Mechanical designers, electrical control most of the designers have 5 years of work experience.With planning and design ability to undertake independent single clamp, hanger, common automatic transmission device of various levels of complexity.In the Japan international iron or set in Taiwan under the guidance of (according to project requirements can be sent as a support) planning and design work can undertake complex production line.
Using INVENTOR (MDT), CATIA, PRO/E, UG as the leading software 3D entity design, and developed on the basis of professional application software and dynamic simulation software.The internal network management, to facilitate the sharing of resources, improve the planning and design work efficiency.
Design standards established a comprehensive system, constantly improve the design level and at the same time, strengthen the schedule management of design project, the corresponding ability improvement.
Since the agency has material welding, car, milling, drilling and other common processing equipment more than 20 Taiwan, CNC machining center, CNC milling machine, CNC cutting machine such as multiple (see list of major equipment).
Outside plant equipment has a good cooperative relationship with:
Large CNC milling machine, machining range: 10000 x 3500;
Import processing center, processing range: 4000 x 2000;
Imported linear cutting machine, accuracy of ± 0.02mm, ± 30 degrees can be cut angle;
Big table of common processing equipment to taiwan.
After years of cooperation (including Japan international iron sent technology plays in the field outside the plant, processing technology, and the main guide) cooperative factory has formed a relationship of mutual trust, interdependence, regardless of quality or delivery is guaranteed.

The large three coordinate measuring machine in Tokyo Trading Co. Ltd. (3000 * 6000), accuracy of ± 0.05;
The large three coordinate measuring machine Beijing nanhanglike of (2000 * 4000), accuracy of ± 0.05;
A Japanese Tokyo trading three portable coordinate measuring machine, accuracy of ± 0.01,
A method such as the United States of America (FARO) portable three coordinate measuring machine, accuracy of ± 0.04,
Multiple digital height gage (Japan, 300 - 1000).
Four sets of three coordinate measuring machines are equipped with dedicated computer software, can automatically read the 3 dimensional data.

After years of development, the comprehensive strength has been continuously improved.In the quality, price, delivery time and the after sale service can provide products to meet customer requirements is our eternal goal.
