Hands-on lab where you can learn about our products

「Want to know how the products I process are actually used」
In response to the exploration of these employees, a training room was created in 2019.

Our philosophy is to engage in manufacturing with an understanding of “products” and ”technology”, and in the training room, students are able to ”assemble and disassemble” actual products. In the training room, students can learn about the true meaning of products, such as why this type of processing is necessasry and why the accuracy of this surface is important.

We also invite ouside lectureswho have actally been involved in the manufacture of our products to give lectures on the difficuluties encoutered during development.

03Senei Sunazuka / Manager, Quality control department, Karuigawa plant

Joined the company in March 2015
What do you usually do ?
In the quality control department, for which I am responsible, I am in charge of finishing, inspection, shipping and packaging, and quality control. Finishing includes deburring and cleaning, while inspection includes dimensional measurement, gauge check, and appearance check,
In quality control, dimensional data is graphed and feedback to the machining department, and advice for improvement is simultaneously sent out to subcontractors in addition to pointing out defects in order to reduce defects.
As a manager, I consider my role to be to implement the PDCA cycle to improve quality. Specifically, I try to create an environment in which the members of the department can work efficiently by considering the causes of defects based on defect data, working on countermeasures, and creating system through discussions with machining and production control departments.
What do you find most rewarding abour your job?
This is where we fell, we are contributing to society. The Karuigawa plant manufactures pump parts mainly for dialysis machines. I am proud that our products are used to protect the lives of people suffering from illnesses. If we inadvertently shipped a defective product ad it had a faulty seal, for example, in the worst-case scenario, the patient’s blood could leak out. This should never happen.
We will continue to make further improvements, realizing that preventing the outflow of defects through quality control is beneficial not only to the company and its suppliers, but also to society.
Senei Sunazuka / Manager, Quality Cntrol Department,Karuigawa plant
What do you find attractive about the company since you joined?
I used to be a sale in food industry, and I simply find it interesting to see how a lump of metal is processed by a machine, polished to shine, and turned into a product.
The Karuigawa plant excels in 24 hours operation with robots and in the machining of complex screw shapes using 5-axis milling machines, a technology that no other company can imitate.
In addition, we have a culture in which young workers actively take on challenges, and they bring us things like, “We have tried to improve our machining, so please inspect it for us. Even if they are busy with other work, they feel like,” okay I’ll have taken a look at it for you. The good atmosphere is another attraction of the company.
What are your goals for the future?
Employees who knew the Yasuda plant when it was built (about 20 years ago) say, it’s hard to imagine what it looked like back then. I have only been with the company for six and a half years, but even in that short time. The company organization has grown rapidly.
To make the next 20 years an unimaginably great leap forward from now, I want to improve quality, meet deadlines, and become an even more trusted presence for our customers.
Finally, to the new workers and mid-career hires who will become my future colleagues.
I mentioned earlier that I was previously a salesman in the food industry, but in fact, when I joined the company,
I was stating form completely blank slate whom it come to metal machining… Even so, thanks to the guidance of my(younger) boss and the careful instruction of my (younger) seniors, I gradually deepened my understanding and now I am entrusted with work as a support of them.
Please do not give up because you have no experience, but take the first step Ans say, “Let’s try it first”.
We look forward to meeting with you and your colleagues who can take on new challenges together.
