SEIRIN is determined to manufacture needles that are reliable and will offer you and your patients peace of mind.

 
SEIRIN controls every aspect of needle manufacturing in-house so we are confident to ensure the quality of every needle we produce.

Needles are made with SEIRIN’s unique stainless steel wire

Manufacturing of all SEIRIN needles is conducted using high quality stainless steel that is manufactured in Japan to our rigorous quality standards.

Straightening technology controllable by 0.001 mm unit

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.

Grinding/Polishing-uniformity technology

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.

Cleaning process

Precise injection molding technology 

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.

Sterility Guarantee

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.

Traceability

A record of the manufacturing details of each needle including information about the shipment, sterilization history and stainless steel wire information can be traced by the lot number and expiration date. These are printed during the packaging process on the backside of the blister pack of each needle. Products lacking clear lot traceability will not be permitted to enter circulation or distribution even if the product passes our shipment inspection.
