Application Areas
The Manufacturing Field of Polyurethane Heavy-duty Industrial Tires
It is core-adapted to the pouring production of various polyurethane heavy-duty tires for trucks, engineering machinery, special operation vehicles and other equipment, and can complete the precise mixing and high-pressure pouring of key parts such as tread, sidewall and reinforcement layer, meeting the use requirements of heavy-duty tires under complex and severe working conditions. At the same time, it is suitable for the customized production of heavy-duty tires with different diameters of 600-1500mm and different thicknesses of 12-50mm.
Technical Highlights
Original Asymmetric Flow Channel Reconstruction Design for Maximized Mixing Uniformity
Adopt an original asymmetric flow channel separation and reorganization structure, composed of mixing units alternately formed by circular curved tubes and rectangular straight tubes, with a cyclic cross layout to form intense chaotic convection in the chamber. After diversion at the feed inlet, the raw materials accelerate to form a high-speed jet in the tapered tube and collide violently with the fluid in the straight tube, increasing the raw material contact area by more than 40% compared with the traditional structure and fundamentally solving the problem of uneven mixing of multi-component raw materials, with a mixing uniformity of ≥98%.
Three-component Synchronous Metering Technology for Precise and Controllable Dynamic Proportioning
The alloy steel mixing head is matched with a high-torque metering pump to realize the dynamic synchronous proportioning of A/B/C three-component polyurethane raw materials, ensuring the precision of raw material mixing ratio from the source. Combined with the closed-cell foaming process, the tire density and hardness error are ≤1.5%, the finished product wear resistance is increased by 25%, the tear resistance is enhanced by 30%, and the service life breaks through industry standards.
39-channel Alloy Steel Mixing Head with High Pressure Resistance and Strong Adaptability
The integrated 39-channel alloy steel mixing head is designed with a pressure resistance grade of ≥25MPa, which can meet the high-pressure pouring process requirements of heavy-duty tires. The alloy steel material has both wear and corrosion resistance, adapting to industrial-grade continuous production. Meanwhile, the multi-channel design realizes uniform flow distribution of raw materials and is suitable for the pouring of 12-50mm thick-walled parts.
Constant Temperature High-efficiency Curing Process for Dual Advantages of Energy Saving and Efficiency Improvement
Perfectly adapt to the aluminum alloy mold + water circulation heating process. The rapid heat conduction characteristic of the aluminum alloy mold shortens the tire curing time by 20%; matched with a pneumatic mold clamping frame, it ensures uniform mold clamping force, effectively avoiding molding defects. At the same time, the comprehensive energy consumption is reduced by 15% compared with the traditional heating method, taking into account both production efficiency and energy saving.
Customized Cleaning Interface Design for Significantly Reduced Downtime
Equipped with an exclusive customized cleaning interface, it can flexibly formulate cleaning agent formulas according to polyurethane raw materials of different hardness, adapting to the cavity cleaning needs of various raw materials. The raw material switching efficiency is increased by 40%, and the equipment downtime for cleaning is reduced by 60%, adapting to the flexible production needs of various specifications of heavy-duty tires.
