Representative President, Hakaru Ichino
Consumer's taste has expanded, and the market now uniquely, demands high quality products. The market for automotive after-market products is growing within this background. In a market where drivers are starting to pursue the joy of driving, and motor culture is maturing uniquely, high quality goods are also needed in the automotive after-market sector. With an eye of the market, and global trends, we have continued to develop suspensions to meet the high demands of the customers. Our first step was OEM production based on our high reliability and engineering skills. In 1990, we went on to produce our own brand products. We believe that we have been able to establish a unique brand image, mainly through sports shock absorbers. Our goal is to become a "total suspension manufacturer who provides driving pleasure to all drivers", and we will continue to strive for higher quality, performance and precision. Our development process will be continuous.
We take pride in our manufacturing technology which does not allow for an inch of compromise. Not only are we set on maintaining our quality, but we have merged in product efficiency by utilizing the most advanced technology in order to deliver the performance that only TEIN can bring about. TEIN is a company specialized in suspension manufacturing, that brings out the best enjoyment out of driving.
The company name "TEIN" was named after a combination of the first two letters, "TE"CHNICAL "IN"NOVATION, as it has been our principle to provide the best products supported by our state of the art technology since we started our business.
All business units certified for ISO9001 International Standard for Quality Management. The certification was received on March 28,2002 from JIC Quality Assurance Ltd. after successful examination. Taking this opportunity,we will further improve quality to meet increasing customer requirements for quality.

Automatic piston rod cutter cuts rods to the specified numbers and lengths.

Transfer milling cutter (Fraser machine) carries out multiple processing milling tasks, such as drilling and grinding.

Automatic gun drill processing machine operates for processing the inner chamber which is indispensable for adjustable damping force shock absorbers.

Automatic pipe-cutter cuts pipes to the specified numbers and lengths.

CNC lathe with bar feeder can be automatically operated by feeding material in the stocker.

The APC equipped machining center initiates batch processing such as drilling and tap processing, per palette, through numerical controls.

Numerically controlled automatic welding robots can achieve uniform welding which assures air tightness and durability.

Shock absorbers are susceptible to dust and dirt. All inner parts are washed by ultrasonic washers.

Precise measurements are needed for shock absorbers and CAD-CAM-CAE systems enables verification from various angles for designing.

By putting the parts which have gone through forging, casting and pressing under tension and compression tests, quality improvement is achieved.

An efficient delivery procedures are achieved through the bar-code delivery verification system, which prevents misdeliver and allows for same day delivery.

All of TEIN production items are validated at the Engineering Department on actual cars, and only products which have passed the tests for ride height, lever ratio, corner weight and drivability are prepared for the mark.
