What is our commitment to quality?

One of the most important elements in manufacturing is a reliable quality control system.We have built a thorough quality control system based on a strong sense of mission that "we cannot tolerate even one defective product in a million."

For this reason, we continue to focus on product precision and strive to provide products that are trusted by customers both at home and abroad.
We will introduce the specific initiatives in our quality control system and our precision measurement technologies.

Reason for high quality ①: Equipped with a wide range of precise and ultra-high-precision measuring instruments

We have introduced the latest high-precision measuring instruments.We have a system in place that allows us to measure outer diameters with a resolution of 0.00001 mm (1/10 mm).

We are equipped with a wide range of measuring instruments, including image measuring machines, roundness testers, surface roughness testers, and hardness testers. By leveraging the unique capabilities of each device, we ensure accurate and reliable measurements.

This wide range of measurement capabilities and high level of precision are something that only a few companies can achieve, and it is an important foundation for our quality control.This measuring instrument also enables us to fulfill orders in the ultra-high precision range.

Measurements in a thoroughly temperature-controlled environment

On the other hand, high-precision measurements cannot be achieved simply by having the necessary measuring equipment.

Temperature control during measurement is also very important.Because,This is because temperature changes can have subtle effects on materials and can cause significant deviations in measurement results.

Metal products in particular expand and contract due to temperature, and simply holding the product for a few seconds can cause a fluctuation of as much as 0.3 μm (10,000/3 of a millimeter).That's why we control the quality through strict temperature control.

By performing measurements in a temperature-controlled room, we are able to verify the true dimensional accuracy of our products. We believe that this temperature-controlled environment is important for stabilizing product quality, and we are extremely particular about it.

Reason for high quality ②: Carefully designed in-house training and management system to improve professionalism and skills

To maintain a high level of quality, the skills of our workers are also extremely important.

We believe that quality cannot be completely controlled simply by having measuring equipment and the correct environment.In our company,All staff members must have a high level of quality awareness and skills.We have established an in-house training system aimed at

New employees and employees being transferred to other departments are given a training period of 1.5 to 2 months during which they receive thorough instruction on quality control and measurement techniques.In this training, an error of ±0.02 μm is acceptable.We support people in acquiring the skills to repeatedly measure with the same accuracy.

Periodic inspection and management of measuring instruments

To guarantee high quality, it is necessary to maintain the precision of measuring instruments.For this reason, the equipment itself is subject to very strict management.

In order to maintain the high accuracy of our measuring instruments,We employ a dual management system that combines precise calibration by an external organization with regular in-house inspections.External inspections are carried out in consultation with the manufacturer to confirm accuracy from a third-party perspective.

We also insist on regular internal inspections.Our in-house inspection and management team is responsible for carrying out in-house inspections and checking the daily usage conditions, especially to prevent errors caused by wear.This management system ensures that accurate measurements and high quality control are always maintained.

Our quality control system consists of a wide range of initiatives, including thorough measurement accuracy, strict environmental management, advanced in-house training, and inspection of measuring instruments.This system allows us to maintain our commitment to quality, with "not even one defective product in a million" being tolerated, and we are able to consistently deliver reliable products to our customers.
