Form the beginning, we do concern about product quality. For this reason we keep developing and designing quality control techniques which are met with the trends in product technology development, starting from making quality system plan, process design, material inspection, until the final test of finished good.

This is what we do continuously to ensure that our products conform to the specific requirements of our customers. We have laboratory to run static test, such as: pressure distribution test using Fuji Prescale Film, thickness on tightening test using Lead Pellet, and water leakage test using Micro Check. We also conduct X-ray test to ensure that the product meets standard specification.
