At present, the domestic automobile transmission enterprises mostly use single-shaft transmissions as their mainstay, and Fast Group is the only company that is dominated by double countershaft transmissions and supplemented by single countershaft transmissions. The advantages of high-, medium-, and low-end heavy-duty transmissions Complementary development of enterprises, and to achieve a scientific product, diversification, serialization, all-round development. Fast double countershaft transmissions are praised by domestic and international markets for their stable quality, excellent performance, strong load-carrying capacity, high cost performance, and convenient service, and have become the standard for most domestic heavy-duty vehicles.

In the past three years, Fast launched new products with fully independent intellectual property rights for heavy-duty transmissions have reached more than 40 kinds. More than 20 kinds of transmission series new products have obtained national invention patents. These new products have a market positioning standard, high technology content, and high cost performance. They provide the latest optimized configuration for the upgrading of the heavy truck market, and are fully adapted to the development needs of the large tonnage heavy truck market. At present, the Fast transmission line has reached more than 20 series and hundreds of varieties. It has achieved full coverage in the 5 to 16-speed transmission field. Transmissions for each gear position can be equipped with synchronizers and are widely matched to the input. Various models with a torque ranging from 500 to 3,000 Nm and a load capacity of 5 to 50 tons are selected as fixed-point supporting products by more than 40 domestic OEMs and are widely exported to the United States, Australia, Eastern Europe, South America, Southeast Asia, and the Middle East. Multiple countries and regions. Among them, the 12-speed, 16-speed dual-shaft transmission series of new products developed by independent innovation are the most representative. The key technologies and core technologies have reached the international advanced level of creativity, not only filling the country's multi-range mechanical heavy-duty transmission. The production gaps have broken the intellectual property barriers created by multinational corporations and formed a competitive advantage for scale development.

The 12-speed, 16-speed dual countershaft transmission is a new generation of high-end products developed and developed by FAST for more than five years to meet the needs of the Chinese market. It has completely independent intellectual property rights, and all its fine-teeth and full-scale transmissions. Synchronizer's technical features, more advanced design, more convenient operation, stronger power, smoother transmission, lower fuel consumption and noise, represent the advanced level of domestic transmission manufacturing. At present, almost all the new models of the national triple-duty trucks introduced by domestic heavy truck companies are equipped with Fast 12-speed, 16-speed dual countershaft transmissions, which fully demonstrates the Fast brand effect.

As the Fast 12-speed, 16-speed double countershaft transmission is a very mature product, it is well adapted to the domestic and international heavy truck market development needs. In 2007, sales and sales volume of Fast 12-speed and 16-speed dual countershaft transmissions exceeded 50,000 units. Its customers include FAW, Dongfeng, China National Heavy Duty Truck, Shaanxi Auto, Sichuan Auto, Beiqi Foton, North Benz and Hualing Auto. Almost all heavy truck OEMs. The two products not only can support 320 horsepower, 420 horsepower, and 480 horsepower, but also provide a technical reserve for future 15-litre and 16-liter engines supporting 500 horsepower and 600 horsepower. At present, heavy-duty truck engines are developing at the national 3 and 4 levels, and the engine speed is reduced. This requires more gear to compensate. For example, the original 2200 rpm and 2300 rpm engines will reach the national 3 emission level. When it is reduced to 1900 rpm, it may be down to 1800 rpm at 4 o'clock. It is necessary to provide more transmission gears to meet the requirements of the maximum climbing grade and maximum speed of the vehicle. The Fast 12-speed, 16-speed dual countershaft transmission fully meets this requirement. In addition, with the increase in fuel prices, more and more gears are needed for mechanical transmissions. The more gears, the higher the power utilization rate will be, and the lower the fuel consumption of the vehicle, this is also FAST. 12-speed, 16-speed dual countershaft transmissions can lead the market.

Acryl Curing Agent

Acrylic curing agents are a type of crosslinking agent used in the production of high-performance coatings and adhesives. Acrylic curing agents are typically used to cure Epoxy Resins, improving their mechanical properties, chemical resistance, and thermal stability.


Acrylic curing agents react with the epoxy functional group to form a thermosetting coating or adhesive. This reaction is exothermic and can be accelerated by heat, making it ideal for high-temperature applications. Once cured, the acrylic modified epoxy resin offers excellent resistance to weathering, UV light, and chemicals.


Acrylic curing agents offer several advantages over other types of curing agents. They are low in viscosity, which makes them easy to handle and mix with epoxy resins. They also have excellent adhesion to a wide range of substrates, including metals, plastics, and composites.


Acrylic curing agents are available in a range of grades, each with its own unique properties and applications. Some grades offer improved toughness and flexibility, while others offer improved chemical resistance or high-temperature performance. The choice of acrylic Curing Agent depends on the specific application requirements, such as cure time, cure temperature, and final properties of the cured epoxy resin.


Acrylic curing agents are commonly used in applications where high-performance coatings or adhesives are required, such as automotive, aerospace, and marine applications. They are also used in the production of electrical and electronic components, where their excellent electrical properties make them an ideal choice.


In summary, acrylic curing agents are a type of crosslinking agent used to cure epoxy resins in the production of high-performance coatings and adhesives. They offer several advantages over other types of curing agents, including low viscosity and excellent adhesion to a wide range of substrates. The choice of acrylic curing agent depends on the specific application requirements, and they are commonly used in applications that require high-performance coatings or adhesives, such as automotive, aerospace, and marine applications.
