Message from the president

In the post-Corona society, companies are being questioned what do companies exist for and what they do business for. Now, we are required to have the significance of a company’s existence that is conscious of its relevance to society that is not satisfied simply by raising sales and making profits and giving it back to society as a tax.

Significance of our company’s existence is “manufacturing” that only we can do, and we will help the clients to improve performance of the equipment which they desire.”

The equipment manufactured by our customers can evolve the final product in various fields, impress the user, and enrich the life.
While, this requires improved equipment performance, but many technical issues must be solved.

As one of the solutions to this issue, the vacuum chamber, water-cooled plate and heat sink which we supply are much useful and contribute to the above.

Based on the philosophy of “Jiri-Rita” (pursuing the interests and happiness of others makes our interest and happiness), we are confident that if the customer’s problems can be solved, the performance of the equipment will be improved and the customer’s customers will be satisfied finally and also at the same time our own processed parts and technologies will evolve and as a result, we will be able to bring happiness and benefits to all the parties concerned.
