Technical data

Product development/quality standardsProduct development/Quality standard

The TOZEN Group has the in-house infrastructure to conduct thorough evaluation testing to ensure that products have the required durability and displacement absorption performance.
We conduct demanding tests to demonstrate that products satisfy customer needs.

Performance evaluation

Repeated pressure fluctuation testing

Product durability and safety is evaluated while bearing in mind pressure differences due to pumps switching on and off.

繰返し圧力変動試験01

Repeated displacement testing

Product performance and safety is evaluated while bearing in mind displacement caused by ground subsidence, mechanical vibrations, etc.

Repeated negative pressure testing

Product durability and safety is evaluated while bearing in mind not only temporary negative pressure, but also repeatedly-generated negative pressure.

繰返し負圧試験

Plant equipment Yoshikawa Headquarters Annex

Plant equipment for which a wide range of evaluation is possible, bearing in mind piping installed on the site. Reproducing cavitation and water hammer is also possible.

プラント設備

Exposure testing

We analyze the effect on our products of exposure to direct sunlight through regular data collection.

暴露試験

Vibration-isolating performance testing Vibration generators and vibration measurement devices

We evaluate the vibration-isolating performance of vibration-isolating materials and flexible joints in order to provide extensive vibration isolation.

防振性能試験

Three-dimensional measurement device

We aim for design and development paying close attention to even small details in order to achieve safety and peace of mind.

三次元測定機1

Optical microscope

We collate data from surface inspections of non-conforming products, working to determine the causes of issues from many perspectives.
