We have 50-years of experience and technology in manufacturing clutch doors used for power-savings to close manhole covers of pressure vessels as well as high pressure sterilization machines. These doors are also used on vulcanizing tanks, various high pressure gas tanks, reaction cans, large size high pressure tanks such as medicine cans for wood, one touch closing mechanisms for vacuum vessels or automatic closing mechanisms. Our tank manufacturing capability is up to 2,600 mm in diameter and about 14,000 L in length. We construct on site if the tank length is more than 20 m. SS, SUS and AL are available as tank materials.

For a better understanding of the clutch door's usability, we created an aluminum model. The model is usually carried by our sales staff and used in presentations, but we also lend the models if you consider using a clutch door.

Our proposal to small -to-medium-sized pressure vessel manufacturers
We can sell door parts only with our clutch door type closing mechanism. We established our market position as a tank manufacturer and continue to increase our value with our experience in clutch door manufacturing.
In our market, every SMC offers its own added value. However, proximity to end-users causes various cost additions and inconveniences for them. We can offer a better value by sharing sales information and maintenance support. We are always looking for a chance to enter into a business alliance and exchange information.
For details, please contact us by E-mail.
We invite you to submit your ideas about our clutch door. We might miss some opportunities to develop new products. Sources of innovation exist everywhere. So please share your ideas with us about closures, gaskets or a flap's spring balance mechanism. Any small idea is welcome. Any style of proposal is acceptable.
If you are interested, please contact us by E-mail.
