A product that is praised as Japan Quality is that each of the precision parts that make it up is of high quality. Even one non-conforming part should not be mixed into the parts delivered to the customer.

Since more than six years ago, we have focused on the importance of 100% inspection and developed and completed a Zero ppm inspection system that does not produce one non-conformity product per million. We interviewed Chairman Hara and President Oishi of NANO SEIMITSU CO., LTD.

The age has come that “Zero Defects” is normal. What is the need for a total number inspection machine!?

Most of the inspection machines handled by NANO SEIMITSU are made in China and Taiwan. Why is there no Japan made machine? Shouldn't Japanese-made be superior to Taiwanese or Chinese-made machines? President Oishi says that customers have often asked such questions. There was a reason for that. In Japan, there has always been an idea that quality control is completed by own-process management. He had absolute confidence in the manufacturing process that would not produce non-conformity parts.

On the other hand, it was Taiwan and China that had no domestic demand and exported the parts they made to Europe and the United States. The mixing of non-conformance parts in these shipments could lead to company bankruptcy. This must not be. It is very natural that inspection equipment has evolved compared to Japan, and it became more sophisticated.

It is not easy to inspect one million total pieces manually. Naturally, finding non-conformity items is nearly impossible. Even now, although the quality of manufacturing has improved dramatically, one or two non-conformities will be produced per one million. It is said that the reason is not a total number inspection but corresponding to the sampling inspection.

However, NANO SEIMITSU has been working on the total number of inspections for more than six years. Customers' requirements scatter widely including "We want to inspect the dimensions," "We want to examine the structure such as hardness," and "We want to automatically sort by appearance." NANO SEIMITSU responds to these demands with an extensive product line-up.
