Handan Haixun: Forging Core Competitiveness of Fasteners with Focused R&D

Handan Haixun Fastener Co., Ltd. has always regarded R&D and innovation as the core strategy for rooting itself in the global market. It deeply cultivates the fastener technology field, focuses on the high-end, green and scenario-based R&D directions, and leads industry upgrading through technological breakthroughs.

The company has set up a professional R&D team and built an industry-university-research innovation platform in cooperation with universities and research institutions. Keeping a close eye on the stringent requirements of new energy, aerospace, high-end equipment and other fields, it focuses on three core technologies: material modification, green coating and precision forming. In terms of material innovation, it prioritizes the R&D of high-end fasteners made of high-strength low-alloy, titanium alloy and other premium materials. Through cryogenic treatment and multi-stage tempering processes, the fatigue life of its products has been increased by more than 50% compared with conventional products. In green technology, it has upgraded eco-friendly processes such as ceramic-based composite coating and chromium-free passivation, with the salt spray test duration exceeding 1,000 hours and energy consumption reduced by 30% compared with traditional processes. In structural optimization, it has developed patented products such as self-adaptive anti-loosening and precision customized fasteners, meeting the high reliability requirements of extreme working conditions such as wind power and nuclear power.

Relying on continuous R&D investment, the company adds more than ten
