Technical expertise in various product and process areas.

Under the skin of each vehicle is the core structure of the vehicle, including the frame longitudinal beam, floor, upper body column and body side rails. By using innovative and high strength materials and manufacturing processes, CTT is constantly developing body structures that meet or exceed our customers' requirements for lightweight and crash performance.

CTT is a market leader in the field of chassis. We use a variety of innovative metal forming processes to meet the specific requirements of our customers, including hydroforming, roll forming, casting, stamping and bending. Integral engine frames and subframes are one of the core products provided by CTT. We use advanced coating technology to develop modular and flexible designs for different regions and products, improving corrosion resistance.

The use of high-strength stainless steel in the passenger car frame instead of carbon steel components, weight reduction of 34%, tooling investment decreased by 30-40%, and corrosion resistance. The technology is mainly used for the sub-frame, but can also be applied to a variety of bodies and chassis to reduce weight.

Cost reduction: minimize material and manufacturing costs Durability: long service life, low life cycle cost Impact resistance: with high strength and high impact resistance Lightweight: minimize the weight of the structure

Product design and development plays an important role in market success.

With a perfect research and development system and efficient transformation of innovative technology production mode, with strong research and development design ability, and strictly control the development process of each link, to ensure the quality and reliability of products.

In terms of the body, we offer integrated development services ranging from preliminary body analysis and body index assessment to body design. As for the chassis, our expertise extends from system integration and digital design to chassis dynamics analysis modules. We are dedicated to providing tailored solutions by thoroughly understanding our customers' market landscape and technical objectives. We are committed to providing quality products and services to meet the needs of customers and future development.

We offer everything from custom designs and fixtures to fully automated fixtures and robotic units, from overall positioning and clamping concepts to CAD design, assembly, measurement and adjustment. Our virtual feasibility testing, reusable standard fixtures and offline and online systems for robot programming can help you save time and costs.

To ensure successful volume production, we manufacture prototypes with the highest quality. We have a wide range of joint technologies available for steel and lightweight joints used in existing automated units, including laser welding, self-piercing riveting, riveting, friction element welding, flow drilling and tightening, flow push, etc.We also offer custom manual processes and automation for prototype and small volume production.

We ensure that all parts are in the right place at the right time, and that the required parts are readily available at every stage of operation. Quality checks, detailed documentation and comprehensive records are maintained at every step of the process to ensure that everything fits together seamlessly.

Parts testing included static warping and torsion, door subsidence, angular stiffness and anti-concave stiffness tests. We developed test procedures, conducted road and off-road tests, performed misuse tests and recorded results.
