For 25 years since the launch, we strived to continue developing our straightening and black oxide coating expertise. Hence, our quality and precision has been highly appreciated by many of our clients. To respond to borderless manufacturing, we have reinforced the application to international industrial standards (such as DIN and MIL). We are also thorough in quality assurance, such as ISO9001, to meet our client’s stringent requirements. We promise to constantly improve our technology so that we can further increase our customer’s satisfaction.
