Focusing on the pain points of heavy-duty impact conditions in the connection of engineering machinery blade plates, we have completed the technical optimization and process upgrade of Blade Bolt products. Through the full chain technology polishing of material formula, heat treatment process, and structural design, we have significantly improved the product's impact resistance, fatigue resistance, and anti loosening performance, providing more reliable connection guarantees for the assembly of blade plates in heavy-duty equipment such as bulldozers.

Yiteng Machinery has been deeply involved in the field of specialized fasteners for many years, and blade bolts are one of its core specialized bolt categories. They are mainly used in key force bearing parts such as bulldozer blade assembly and blade angle mechanism connection, directly affecting the stability of blade operation and the reliability of equipment operation.

In response to the operational characteristics of blade bolts that are subjected to strong impact loads, alternating stresses, and outdoor abrasive erosion for a long time, the company has carried out targeted optimization at the core technology level. High strength alloy structural steel is selected as the material, and the mechanical properties of the material are controlled through precise quenching and tempering heat treatment process, so that the product has both high tensile strength and excellent impact toughness, and can withstand the continuous impact load of the blade during heavy-duty operation without easy fracture; Optimize thread profile design and precision machining process, improve thread engagement tightness, enhance anti loosening performance, and effectively reduce the risk of loosening and slipPing under long-term vibration conditions; At the same time, it can be matched with various surface anti-corrosion and wear-resistant treatment processes to enhance the product's corrosion resistance and wear resistance, and adapt to complex outdoor working environments such as sand, dust, salt and alkali.

At present, the company's blade bolt products have fully covered the four mainstream standard systems of national standard, German standard, Japanese standard, and American standard, and can provide full strength grade products of 8.8, 10.9, and 12.9, which can be adapted to global mainstream construction machinery brands such as Caterpillar, Komatsu, Volvo, Daewoo, Shengang, Hyundai, and Liebherr. At the same time, corresponding specifications of Nuts are supplied to meet customers' one-stop procurement needs. In addition to standard specifications, the company also has the ability to customize non-standard technical specifications, and can customize product parameters according to customers' special machine models and working conditions.

In terms of quality control, the entire series of blade bolts are strictly produced in accordance with the ISO9001-2000 quality management system standard, and a full process quality traceability mechanism covering raw material verification, production process control, and finished product performance testing is established. Key indicators such as dimensional accuracy, mechanical properties, and surface quality are strictly verified batch by batch to ensure stable and consistent product performance before leaving the factory. With self operated import and export rights, the company's blade bolt products have been exported to dozens of countries and regions such as Europe, the United States, Canada, Australia, etc., and have been widely recognized by customers at home and abroad for their stable and reliable technical performance.

Ningbo Yiteng Engineering Machinery Co., Ltd. has always adhered to the business principle of "quality first, customer first, reasonable price, and reputation first", and continuously cultivated the core technology of specialized fasteners. In the future, the company will continue to promote the technological upgrading of core products such as blade bolts, continuously expand product application scenarios and global market territory, steadily move towards modern management, enterprise scale, and brand internationalization, and provide more valuable connection technology solutions for the global construction machinery industry.
