SEIRIN Co., Ltd. uses vertically integrated production systems and advanced nanotechnology to develop acupuncture needles trusted by medical professionals world-wide.
In line with Japanese Industrial Standards, our high-quality stainless-steel wires are produced from the best raw materials under the company’s strict selection standards.
Manufacturing of all SEIRIN needles is conducted using high quality stainless steel that is manufactured in Japan to our rigorous quality standards.
Our Straightening technology allows us to control the precision of many aspects of manufacturing including exactness of needle diameter and straightness. This technology helps to ensure our quality and consistency.
We value the cleaning process as it will directly affect the sensation of treated patients if any foreign matters remain on the needles. We clean the needles using specific solutions in a controlled environment.
Using SEIRIN’s original needle tip processing technology, it is possible to achieve a uniform rounded and smooth needle tip shape that minimizes pain. After the needle processing is completed, an in-process inspection is carried out on a batch basis, and the shape of the needle point and the dimensional accuracy of the needle length is strictly screened.
Throughout our history, our company has been researching, innovating, and perfecting our needle tip designs. It is through the fusion of passion, engineering craftsmanship and technology that we are able to continuously improve our products and produce the highest quality needles in the world.
It is very important to thoroughly clean a needle to remove any foreign substances left over from manufacturing. Our cleaning process is very involved using acid, alkaline, ultrasonic and distilled water baths in extremely regulated environments.
Through many years of experience and technological improvements, we are able to securely connect the needle shaft to the exact center of the needle handle. This helps facilitate steady needle insertion and result in less damage of the tissue as the needle is twisted to stimulate the acupuncture point.
We guarantee the sterility of our products using EOG (ethylene oxide gas) sterilization processes. Furthermore, we have achieved a sterility assurance level (SAL) of 10-6, demonstrating that our sterilization process meets extremely high sterility standards.
