Our Technologies

Metal Forming

To meet diverse customer needs, we have internalized a wide range of forming techniques and offer proposals for the most suitable processing methods.

Cold Press Processing

G-TEKT’s cold press technology is capable of handling a wide range of materials, from mild steel to ultra-high-tensile steel sheets.

As tensile strength increases, metal forming becomes more challenging; nevertheless, we have established advanced metal forming technologies for components made from 1.5 GPa-class ultra-high-strength steel (UHSS), enabling us to achieve lightweighting and enhanced crash safety while maintaining consistent quality.

Hot Stamping Technology

Hot stamping is a forming process in which heated steel is shaped and quenched simultaneously to produce high-strength components. Heating softens the steel, improving formability, while quenching significantly increases its strength. This process makes it possible to achieve the required strength with thinner materials, enabling the production of lightweight yet highly rigid vehicle bodies.

G-TEKT has developed hot stamping technology that joins materials of different thicknesses and properties. While low productivity had traditionally been a challenge, we have enhanced efficiency by applying various proprietary (patented) die structures and precisely controlling the cooling process.

Aluminum Forming

 

 

Aluminum is about one-third the weight of steel, but high-speed continuous press processing has traditionally been a challenge. Recognizing its potential early on, G-TEKT mastered aluminum forming technology and has achieved production at speeds comparable to steel processing, thereby meeting customer needs.

Precision Press Technology

G-TEKT’s precision press technology uses proprietary thickening and thread-rolling processes to achieve high-precision, complex shapes that were once difficult to form by pressing. It enables processing to within thousandths of a millimeter and mass production of parts that previously required machining. In particular, our proprietary oblique press forming—pressing with the workpiece held at an inclined angle—enables high-speed production on transfer presses, allowing efficient manufacture of components with complex tooth profiles.

Roll-Forming Technology

Roll-forming is a process in which material is gradually shaped by passing it between continuous upper and lower forming rolls. This method makes it possible to create cross-sectional shapes that are difficult to achieve with press forming.

We have achieved aluminum roll forming and continue to expand our technological capabilities.

Joining

We have extensive mass production experience centered on resistance spot welding. Selecting the optimal joining method requires careful consideration of material combinations and properties, as well as the required strength, reliability, and productivity.

G-TEKT meets the diverse needs of automobile OEMs through a wide range of joining technologies.

Looking ahead, we are advancing initiatives that go beyond conventional joining by introducing and expanding unmanned production lines.

Equipment Design

Our in‑house–designed welding lines can be built in a short lead time by leveraging advanced simulation technologies, and they flexibly adjust production volumes in sync with automakers’ production plans.
In addition, we propose proprietary robotic systems—developed by applying the expertise gained from our own equipment—to our customers.

Robot Systems Integration Business

As a robot systems integrator, we deliver robotic systems and assembly equipment—leveraging the know‑how and new technologies cultivated through our own mass‑production facilities—to customers across a wide range of industries, not limited to the automotive sector.
