江崎工業 Company Profile

Ezaki Industrial Co., Ltd. will be exhibiting at the "6th Automotive Parts & Processing EXPO" held at Tokyo Big Sight (West Exhibition Hall). We will showcase various combinations of "pipe diameter" and "number of corrugations," including widely adopted "expansion joints (bellows)" for stress mitigation in applications such as EGR pipes and oil return pipes. [Booth Number: W27-26] We sincerely look forward to your visit.

This is a product of pipe expansion and contraction using a punching process. We have achieved a longer processing distance than conventional methods without using hydraulic forming. While hydraulic forming is a method that does not cause molding defects for long-distance pipe expansion and contraction, it requires specialized molding equipment, resulting in high production costs, and necessitates sealing liquid or gas inside the pipe during the forming process. Our pipe expansion and contraction processing using the punching method eliminates these issues and allows for processing at a lower cost. Of course, bending after processing is also possible.

Ezaki Industrial Co., Ltd. will be exhibiting at the 2nd [Nagoya] Automotive World - Advanced Automotive Technology Exhibition - held at Port Messe Nagoya. A total of 400 companies with technologies related to advanced themes in the automotive industry, such as autonomous driving, EV/HEV, car electronics, connected cars, and lightweighting, will be exhibiting together. We sincerely look forward to your visit.
