1. Forward-looking Layout, Building a Core Technological R&D Barrier
Yongjing Precision firmly believes that only by mastering core technologies can we have a voice in the market. We are not content with merely meeting standards; we strive to define and surpass them.
The company has established an advanced technology R&D center led by senior engineers and industry experts. This center is not only the cradle for incubating new products and processes but also the frontline for addressing industry pain points. Targeting the challenge of "early fastener failure" commonly faced by the high-end equipment manufacturing industry—especially key performance bottlenecks such as stress corrosion cracking, insufficient fatigue strength, and high-temperature creep—our R&D team has conducted in-depth tackling. Through material microstructure analysis, surface treatment process optimization, and simulation testing, we have successfully developed multiple series of high-performance specialty fasteners. For instance, our "Stress Corrosion Resistant Duplex Stainless Steel Fasteners" significantly enhance corrosion resistance in chloride ion environments by adjusting alloy composition and adopting special solution treatment technology. Their lifespan is several times longer than that of ordinary austenitic stainless steel fasteners, and they are already widely used in harsh working conditions such as marine engineering, chemical equipment, and new energy vehicle battery packs. Furthermore, our R&D system features a high degree of customization and rapid response capability. A customer's concept or even a rough sketch can be transformed into a mature and reliable product solution in our R&D center. From material selection, structural design, and process planning to sample trial production, we have formed an efficient and smooth closed-loop process, ensuring that personalized customer needs are met in the shortest time possible, making us a trustworthy partner in our clients' new product development journey.
2. Striving for Perfection, Establishing a Full-Process Quality Assurance System
Excellent product quality stems from precise control over every manufacturing link. Yongjing Precision has built a full-process, traceable quality assurance system covering raw materials, in-process production, and finished goods.
In the raw material control stage, we have established strategic partnerships with renowned domestic and international steel mills to ensure the stability and reliability of the material source. All raw materials entering the warehouse must undergo a strict "physical examination" by our testing laboratory, including spectral composition analysis, mechanical property testing, and metallographic structure observation, eliminating unqualified products from entering the production line at the source.
During the manufacturing process, we have introduced advanced quality management tools such as Statistical Process Control (SPC) to conduct real-time monitoring and data analysis of key processes like cold heading, thread rolling, heat treatment, and surface treatment, ensuring the stability and control of process parameters. Our heat treatment production line adopts intelligent controlled atmosphere protection technology, effectively preventing oxidation and decarburization of products during high-temperature processing, and guaranteeing the high consistency and reliability of the fasteners' core mechanical properties (such as strength, hardness, and toughness).
3. Authoritative Certification, Building World-Class Testing Capabilities
Testing capability is the "eyes" of quality management. Yongjing Precision has invested heavily in building a national-level standard laboratory accredited by CNAS (China National Accreditation Service for Conformity Assessment). This accreditation signifies that our testing equipment, environment, personnel skills, and management system have all reached international standards, and the test reports issued carry global credibility.
Our laboratory possesses comprehensive fastener performance testing capabilities, including but not limited to:
-
Mechanical Property Testing: Tensile strength, yield strength, hardness, proof load, wedge load, etc.
-
Fatigue Performance Testing: Life assessment under simulated high-frequency alternating stress.
-
Environmental Reliability Testing: Salt spray tests, constant temperature and humidity tests, sulfur dioxide corrosion tests, etc.
-
Metallographic and Physical/Chemical Analysis: Material structure evaluation, surface coating thickness measurement, hydrogen embrittlement testing, etc.
This complete testing system not only provides a solid "certificate of conformity" for outgoing products but also offers precise data support during the product development stage, accelerating R&D iteration. By moving quality control checkpoints forward, we have truly achieved a qualitative leap from "post-event inspection" to "pre-event prevention." Our ultimate goal is to deliver "zero-defect" products to our customers, giving them complete peace of mind.
