We began the development of the material after receiving a request from customers to suppress the engine noise on construction machinery out of consideration for the people nearby. We conducted research into high performance materials and structures that could replace the urethane and glass wool used previously. The result was the birth of the “QonPET”® high performance sound absorbing material made from non-woven polyester fabric. We searched for the optimal level of fiber density and the product was finally completed after the evaluation of dozens of prototypes. The durability has been improved and also the weather resistance is improved from that of urethane and the workability is improved from that of glass wool.

A certain railroad company had been attempting to perform damping for a highly sensitive sensor by installing cushion rubber, but had not been able to suppress the vibration. By utilizing our sophisticated rubber technology in our research and development, we were able to obtain a sufficient effect with an original rubber vibration isolator for light loads that we developed ourselves. We succeeded in preventing the damage to the sensor instrument.

We proposed original dampers to solve the problem of noise and vibration in the engine room of an automobile. This was selected after comparing multiple manufacturers, for high level damping due to the high specific gravity and excellent workability. In addition to the customers being pleased with the high damping effect, we were also able to promote the appeal of its cost merits.

Filters are used for various roles depending on the size of the dust particles to be removed. We choose from a large range of materials manufacturers to propose the materials and profile necessary to fit the order from the customer within the limitations of the cost.

We received an inquiry from a customer about the waterproofing of an electrical transmission box that was placed outdoors. We therefore interviewed the customer about the installation location and the shape of the fit. We considered what level of waterproofing would be necessary for the sealing material in the environment of the installation and selected materials. Before making the request, the customer had been using low compression urethane sponge material. However, on consideration of the environment for use outdoors, we managed to stop the water with a high compression EPDM rubber foam material with closed cell foam.
