latest company case about Shenzhen Huayuanxing Precision Hardware Co., Ltd. Certifications

Empowering electronic terminal accessories, precision screws support product quality.

In the smart phone and accessories industry, the precision, corrosion resistance and adaptability of micro fasteners directly affect the product assembly yield and service life. When a well-known electronic accessories manufacturer developed the matching fasteners for the new wireless headset charging box, it encountered the core bottleneck: it was necessary to customize the CM precision electronic screws with an outer diameter of 1mm and a length of 3mm, to adapt to the ABS plastic shell of the charging box, to be lightweight and have good insulation, and to complete the supply of 300,000 pieces within 10 days, and to support small-sized packaging to avoid screw loss during transportation. By word-of-mouth recommendation, the manufacturer established a cooperative relationship with Huayuanxing.
After receiving the demand, Huayuanxing's eight senior engineers and technicians quickly docked, combined with the lightweight and insulation requirements of electronic accessories, and accurately selected nylon plastic as the screw base material. Compared with traditional metal materials, it not only met the insulation safety requirements of charging boxes, but also effectively reduced the weight of accessories. At the same time, based on 20 years of precision machining experience, the thread density and head structure of CM type screws are optimized to ensure accurate occlusion with plastic shell and avoid the problems of thread slipping and loosening during assembly. At the production end, with the help of the exclusive production line composed of more than 250 precision production equipment, the core processes such as threading and thread rolling are quickly started, and the order production is efficiently promoted by relying on the daily production capacity reserve of 20 million pieces.
In the quality control link, Huayuanxing accurately calibrates the outer diameter, length and thread accuracy of each batch of screws through a secondary detector to ensure that the error is controlled within the industry standard; At the same time, according to the characteristics of nylon material, the temperature resistance and wear resistance tests are carried out to ensure that the screws can adapt to the daily use scene of the charging box. According to the customer's customized packaging requirements, the team designed independent sealed small packages, repackaged according to the specifications of 300 pieces per box, marked the product model and adaptation scenarios, effectively reduced the loss during transportation and storage, and adapted to the needs of customers' automated assembly lines.
With the flexible deployment of more than 3,000 tons of spot inventory and mature production links, Huayuanxing completed the production, testing and delivery of 300,000 nylon CM precision screws in just 8 days, 2 days ahead of the customer's expectation. In the follow-up batch cooperation, the product was tested by the customer's million-level assembly, and the assembly yield reached 99.8%. None of the accessories were repaired due to screw quality problems. At the same time, the direct supply mode of the source factory saved the customer 20% procurement cost. At present, the cooperation between the two parties has extended to the supply of fasteners for a full range of accessories such as chargers and data cables, and Huayuanxing has become the exclusive fastener partner of this manufacturer.
In the intelligent electrical robot industry, the fastening accuracy and stability of the core components directly determine the operation efficiency and service life of the equipment. A domestic head intelligent robot manufacturer once faced a core problem: its new small cooperative robot has a compact body, which needs to be fitted with miniature precision screws with an outer diameter of 1.2mm and a length of 4mm, which requires both high-strength fastening and corrosion resistance, and needs to complete the first batch of 500,000 pieces in 15 days, and at the same time, it needs customized packaging to facilitate automatic assembly. After multi-party screening, the company finally chose to reach a cooperation with Huayuanxing.
After receiving the demand, eight senior engineers and technicians from Huayuanxing quickly stepped in. With 20 years of industry accumulation, combined with the material (aluminum alloy) of the robot body, 304 stainless steel was accurately selected as the base material to match the core parameters of PA miniature precision screws, and at the same time, the thread structure was optimized to improve the fastening bite force. At the production end, relying on the full-process production line composed of more than 250 precision production equipment, we quickly start the processes such as heading, cold pier and thread rolling, strictly control the dimensional error of each process, and stably output the strength of 20 million pieces per day to ensure the efficient promotion of the first batch of orders.
In the quality control link, Huayuanxing inspected the outer diameter, length and thread accuracy of screws batch by batch through the secondary detector, and completed the 72-hour corrosion test by using the salt spray tester to ensure that the products adapt to the complex operating environment of the robot and eliminate the hidden dangers of corrosion and looseness. According to the customer's customized packaging requirements, the team simultaneously provides packaging solutions in boxes, packaging according to the specifications of 500 pieces per box, marking the product model and material, and adapting to the feeding needs of customers' automated assembly lines.
With the flexible deployment and large-scale production capacity of more than 3,000 tons of spot inventory, Huayuanxing completed the production, testing and delivery of the first batch of 500,000 PA micro screws in just 12 days, 3 days ahead of the customer's expectation. In the follow-up batch cooperation, the products have been tested by customers for a long time. After 100,000 times of continuous operation, the performance of the products is zero failure, and the qualified rate of dimensional accuracy remains 100%, which not only solves the urgent supply and quality problems of customers, but also saves 15% of the middleman procurement cost for customers by virtue of the advantage of direct supply from the source factory. At present, Huayuanxing has become the core fastener supplier of the enterprise, and its cooperation scope extends to a full range of accessories such as screw bars and locknuts.
Multi-field deep empowerment, creating a new paradigm of direct supply from the source
Similar to the above-mentioned cases, relying on precise technology, more than 14,000 product specifications, diversified material selection and stable quality, Huayuanxing products have widely penetrated into many production fields, such as computers, communication equipment, intelligent appliances and robots, watches, glasses, instruments and meters, auto parts, LED lamps, small household appliances, medical devices, toys, furniture, architecture and so on, providing reliable fastener support for industrial upgrading and product assembly in various industries.
As the source factory, Huayuanxing adheres to the factory direct supply wholesale mode, saves the price difference between middlemen and provides customers with cost-effective solutions. At the same time, with a perfect service system, we provide professional support from product selection, customization and adaptation to after-sales response, and truly realize "one-stop procurement and all-round guarantee" to help downstream enterprises reduce costs and increase efficiency.
In the future, with the transformation of manufacturing industry to precision and intelligence, the fastener industry will usher in new development opportunities. Huayuanxing will continue to uphold the ingenuity of 20 years, deepen the field of precision fasteners, continuously optimize the production capacity structure, expand product categories, and improve the service level, so as to empower more industries to develop with high quality with the strength of the whole chain, and demonstrate the hard strength of the original factory in China.
