Wholesale Agricultural Trailers Solid Tyre Manufacturers

What are the manufacturing processes of agricultural trailers solid tyre

Raw material preparation and formula design
Jiangsu Topower Tyre Co., Ltd. knows that raw materials are the cornerstone of product quality, so it adopts strict screening standards in the selection of raw materials. We focus on the selection of key raw materials such as rubber and fiber materials to ensure that they meet international high quality standards. The company has brought together a professional R&D team and has established in-depth industry-university-research cooperation with many universities such as Yangzhou University, Qingdao University of Science and Technology and Xuzhou Industrial Vocational and Technical College. In view of the complex working conditions of agricultural operations, we have carefully designed a variety of rubber formulas. By adjusting different types of rubber and ingredients, we optimize the grip of dry and wet land and reduce the rolling resistance coefficient, so that the tire can show excellent performance under various terrain and climatic conditions.
Mixed and calendering process
Mixed process is a crucial part of the tire manufacturing process. Jiangsu Topower Tyre Co., Ltd. uses a large internal mixer to fully mix rubber, ingredients and additives under high temperature and high pressure. The internal mixing process is divided into two stages, and the temperature and time are strictly controlled to avoid damage to the additives and ensure the high quality of the rubber compound. The calendering process combines the rubber mixture with the cord or steel wire to form a high-strength cord layer and belt layer. Our company is equipped with advanced calendering equipment, which uses three or more counter-rotating chrome-plated steel rollers. Through precise temperature and pressure control, the rubber and the cord or steel wire form a good bond, providing strong structural support for the tire.
Manufacturing of tread, sidewall and airtight layer
The tread is the key part of the tire in contact with the ground, and its performance directly affects the agricultural trailers solid tyre's grip and wear resistance. Jiangsu Topower Tire Co., Ltd. uses advanced extrusion technology to extrude three different formulas of rubber mixtures through different extruders at the same time and merge them into a common extruder head to form a tread with excellent performance. The manufacturing process of the sidewall and airtight layer is similar, but different rubber compounds and manufacturing methods are used according to their functions and structural characteristics. The airtight layer uses butyl rubber or chlorobutyl rubber to ensure that the tire has low permeability, thereby effectively maintaining the stability of air pressure.
Assembly and vulcanization process
During the assembly process, Jiangsu Topower Tyre Co., Ltd. precisely combines all tire components to build a complete tire structure. We use a two-stage assembly process to ensure the close fit and stable performance between the components. Vulcanization is the last key process in agricultural trailers solid tyre manufacturing. It cross-links the rubber molecules through high temperature and high pressure, thus giving the tire elasticity, strength and wear resistance.

What are the causes of damage to the carcass structure of agricultural trailers solid tyre?

The relationship between air pressure management and solid tire performance
During the use of agricultural machinery, air pressure management is an important factor affecting the performance of agricultural trailers solid tires. Insufficient air pressure will trigger a series of chain reactions, resulting in carcass damage. When the tire pressure of a solid tire is lower than the standard value, the sidewall will be excessively deformed. This deformation will cause the cord layer to be continuously stretched, thereby accelerating the failure of the bond between the rubber and the cord. Research data from the laboratory of Jiangsu Topower Tyre Co., Ltd. shows that the risk of fatigue fracture of the carcass cord increases by more than three times when running at low air pressure for a long time. For example, during a spring operation on a farm, the solid tire sidewalls developed stepped cracks due to the failure to replenish air pressure in time, which is a typical case of damage caused by insufficient air pressure.
On the other hand, air pressure overload can also cause serious damage. When the tire pressure exceeds the standard value, the middle of the tire crown will be over-pressurized, and the tensile stress of the cord layer will exceed the design threshold. The intelligent tire pressure monitoring system developed by the company recorded an extreme case: a certain agricultural machinery operated at 120% of the standard air pressure in a high temperature environment, resulting in delamination of the tire crown rubber and partial melting of the cord layer, which seriously affected the service life and safety of the tire.
The impact of overload operation on tire body materials
In agricultural operations, trailers often need to carry cargo that exceeds the design load capacity, especially in complex road conditions such as mud, sand and gravel, and agricultural trailers solid tires need to withstand additional shear forces. Through finite element analysis, Jiangsu Topower Tire Co., Ltd. found that when the overload reaches 20%, the temperature of the stress concentration area inside the tire body will rise by 15°C, which will accelerate the aging of the rubber and the breakage of the cord.
In addition, when agricultural machinery is frequently started, stopped and turned, the dynamic load on the solid tire far exceeds its static load-bearing capacity. The fatigue testing machine developed by the company verified the conclusion that overload operation shortened the fatigue life of the tire material by 40% when simulating field operation conditions. This finding emphasizes the importance of reasonable load and operation methods.
Manufacturing process defects and structural hidden dangers
During the manufacturing process, if there are defects in the bonding process between the cord and the rubber, it will easily form delamination during long-term use. Jiangsu Topower Tyre Co., Ltd. uses nano-level adhesives and dynamic vulcanization technology to increase the peel strength between the cord and the rubber to 1.8 times the industry standard, effectively avoiding such risks. In addition, improper temperature and time control of the vulcanization process may also cause uneven cross-linking of the rubber molecular chain, forming local weak points. The intelligent vulcanization production line introduced by the company controls the vulcanization uniformity error within ±2% through an online monitoring system, significantly reducing the probability of structural damage.
External environment erosion of agricultural trailers solid tires
In agricultural environments, chemicals such as pesticides and fertilizers are corrosive to rubber, posing a threat to agricultural trailers solid tires. To meet this challenge, Jiangsu Topower Tire Co., Ltd. added anti-aging agents and corrosion-resistant additives to the formula, so that agricultural trailers solid tires can still maintain stable performance in an environment with a pH value of 3-11.
At the same time, extreme temperatures are also a big test for agricultural trailers solid tires. Low temperatures will cause rubber to harden, while high temperatures will accelerate the aging of rubber. To this end, the company has developed a cold-resistant and heat-resistant formula that allows the tire to maintain excellent flexibility and strength in a temperature range of -40℃ to 80℃, thereby effectively coping with various extreme climate conditions.
