Industry Status
The scale expansion of shock absorber companies reflects the rapid development of this market. Domestic shock absorber products, especially car shock absorbers, have a relatively high level of production.
Han Ding analysis believes that the domestic vibration damper manufacturing level has been greatly improved, the main engine plant supporting a large proportion, in the middle and low-grade cars, the basic is the country made shock absorbers. In addition, the technical level of shock absorbers has gradually increased, and the gap with the international advanced level is narrowing. High-end products also have R&D, although the number is still relatively small.
With the increase in the level of production and after-sales service, the domestic exports of shock absorbers are also increasing year by year.
Commercial vehicle shock absorber market is "revealing"
At present, the red fire in the shock absorber market is mostly manifested in the field of cars, and the development level of commercial vehicle shock absorbers is worse. Han Ding believes that the slower development of shock absorbers for commercial vehicles is mainly due to the smaller market. The main function of the shock absorber is to improve the comfort of the vehicle, while commercial vehicles have long been regarded as production materials, and there is insufficient attention to comfort. Bus shock absorbers are now widely deployed, but many trucks do not use shock absorbers. Trucks in mines, mines, and other areas are overloaded with shock absorbers that are factory-installed.
The shock absorber market for commercial vehicles has developed rapidly in the past two years. In general, sedan cars are equipped with four shock absorbers, and the newly released high-end trucks are now equipped with six shock absorbers. As the market matures, the production level of shock absorbers for commercial vehicles will certainly continue to increase.
The technology gap remains obvious
Although the market for shock absorbers in China is growing at a faster pace, Han Ding indicated that the gap between the technology level of domestic shock absorbers and international advanced products remains significant.
Han Ding believes that the technical difficulties of shock absorbers are mainly in the vehicle matching. Because many parts of the car's tires, engines, and transmissions can become vibration sources, how to eliminate the impact of the vibration source during the running of the vehicle is the most important work in the shock absorber R&D process. The gap between domestic shock absorber companies in this area is still relatively large.
In addition, the technical level of the shock absorber related industries are uneven, often due to the lack of quality rubber parts, oil, etc., resulting in failure of the shock absorber.
The McPherson-type suspension shock absorbers used in large-scale domestic high-end cars have a certain gap in reliability. The air spring dampers equipped on high-end passenger cars basically rely on imports. In addition, the internationally advanced shock absorber has been developed into an electromagnetically adjustable type, and the human and the vehicle are properly matched, and the microcomputer is actively controlled by the microcomputer, so that the comfort is very good. However, domestic high-end products are only highly adjustable and are relatively low-level passive adjustments.
Forged Crane Wheel offers uniformity of composition and structure. Forging results in metallurgical recrystalisation and grain refinement as a result of the thermal cycle and deformation process. This strengthens the resulting steel product part particularly in terms of impact and shear strength. Forged steel is generally stronger and more reliable than castings and plate steel due to the fact that the grain flows of the steel are altered, conforming to the shape of the part. Advantages of forged crane wheel:
· Generally tougher than alternatives.
· Will handle impact better than castings.
· The nature of forging excludes the occurence of porosity, shrinkage, cavities and cold pour issues.
· The tight grain structure offers great wear resistance without the need to make products"superhard" We have found that, on a blank HRC3842 forged grinder insert wear/wash is about the same as a high alloy HRC46-50 grinder insert.
