About quality management

We will implement thorough quality control to ensure that you can use our products with confidence.

In the product inspection area where quality control is conducted, high-power air purifiers are installed as equipment to prevent the intrusion of foreign substances and dust. The inspection room is carefully partitioned with clear curtains, and if the customer has specific standards, inspections can be conducted based on those criteria. ● Fabric Inspection In the clean room where product inspections are conducted, air purified by HEPA filters is continuously ventilated from above, allowing inspections to be carried out in an environment that removes over 99.99% of dirt particles measuring 0.3μm. Fabric inspection is the first stage of inspection, where containers before processing, such as printing and hot stamping, are examined. Various inspections are conducted for dirt, scratches, deformation, foreign matter contamination, and more. This is an important inspection that helps reduce the defect rate by avoiding unnecessary processing of defective fabrics. ● Finished Product Inspection Containers after decoration, such as printing and hot stamping, are inspected. This is the final inspection before shipping products to customers. Inspections are conducted for misalignment of decoration, peeling, color tone, dirt, and other factors. ● Various Inspections Suitability inspections of containers and their accessories are conducted using vacuum tests and torque meters. In-house operations include inserting seals into caps and adjusting the length of dispenser pipes.
