Maruyasu Quality Policy

Utilization of visualization technology
Activities to identify the root cause of problems
and make good products.
We use it to pursue better manufacturing methods by understanding what kind of changes are occurring
by processes and to identify the root cause when a problem occurs.
Utilization of eye camera
Creating a system that enable anyone to
make good things.
We have created a video manual using images taken with an eye camera so that anyone can understand the inspection process without omission.
In addition, we use an eye camera to analyze the movements and viewpoints of workers.
It helps us to check and improve workers’ understanding level.


Utilization of virtual images
Design a manufacturing line that can build quality
from the conceptual stage
We set up facilities virtually and designing optimal processes.
From the conception stage, we are thinking about how to reduce difficult work and make good products more efficiently.


Utilization of AI technology for product inspection
A system that assures good things with confidence.
By eliminating variations in inspections by workers,
we supply products with appropriate quality to post-processes.
