The average delivery time is 7-20 days, the company has a number of models in stock all year round, and individual models can be shipped quickly.The company has passed ISO9001/ISO14001/ISO45001/SGS certification, and the company’s products have also passed the national testing.
1. Overview of the manufacturing system
DABANG factory has built a complete vertical manufacturing system for fasteners, equipped with eight intelligent production lines, covering the entire process from raw material processing to finished product delivery. The core production area adopts a modular layout, and each fastener production line is equipped with a multi-station cold heading forming unit imported from Germany, and cooperates with a servo motor closed-loop control system to achieve ±0.01mm dimensional accuracy control of standard parts with nominal diameters of M6-M24. The production line integrates an online annealing device and a surface phosphating pretreatment module, and realizes automatic adjustment of process parameters through a PLC control system. The material utilization rate reaches 98.2%, and the unit energy consumption is reduced by 37% compared with traditional processes.
2. Surface treatment process matrix
Five fully automatic surface treatment lines form a complementary process matrix: Line 1 adopts zinc phosphating process with a film thickness of 8-12μm; Line 2 is equipped with a Dacromet coating system, and the salt spray test exceeds 1000 hours; Line 3 is an environmentally friendly hot-dip galvanizing production line equipped with a vibration zinc nodule removal device; Lines 4-5 adopt differentiated designs, respectively for electrophoretic coating and DACROMET chromium-free treatment processes. The treatment line is equipped with a three-stage countercurrent rinsing system and a wastewater recovery device, which complies with the GB8978-2002 sewage discharge standard, with an annual processing capacity of 15,000 tons.
3. Quality inspection system
The 200㎡ standardized inspection room is equipped with 32 sets of inspection equipment such as a spectrometer, Rockwell hardness tester and a microcomputer-controlled universal testing machine. Implement ISO/IEC17025 management system, key indicator detection capabilities include:
1. Mechanical properties: tensile strength (up to 12.9 grade), guaranteed load, wedge load
2. Metallographic analysis: decarburization layer depth (≤0.02mm), microstructure
3. Environmental tolerance: neutral salt spray test (ASTM B117), cyclic corrosion test
Implement full-size detection + statistical process control (SPC) dual-track mechanism, process capability index Cpk≥1.67.
4. Intelligent packaging system
In order to optimize the production process and achieve efficient packaging, the DABANG factory is equipped with five high-precision bagging machines that can process 500-800 bags of materials per hour. It is also equipped with three automatic cable tie automatic packaging machines. The fastening force of the cable tie is uniform and stable, which effectively ensures the integrity of the product packaging and transportation safety.
5. Warehousing and logistics configuration
The 7,000㎡ stereoscopic warehouse adopts the WMS warehouse management system, sets up a 12-meter-high shelf system, and is equipped with 5 aisle stackers and 8 AGV transporters. The inventory turnover rate is controlled within 18 days, supporting the JIT delivery mode. The temperature and humidity control system maintains a storage environment of 30%RH±5% to prevent the risk of hydrogen embrittlement of fasteners.
Through intelligent equipment upgrades and process innovations, the DABANG factory has built a manufacturing system covering the entire life cycle of fasteners, reaching industry-leading levels in process control accuracy, quality stability and delivery efficiency, fully reflecting the development direction of modern manufacturing enterprises towards intelligence and greenness.
