II. Stable Euro-style Wheel Design for Easy Mobility
The aviation case is equipped with 3.5-inch Euro-style wheels, which are designed with full consideration of mobility and stability. The 3.5-inch wheel diameter ensures sufficient load-bearing capacity while easily handling various types of flooring, whether it be smooth floors or slightly uneven surfaces, allowing the case to move smoothly. The Euro-style wheels have a well-designed structure, offering excellent wear resistance and pressure resistance, capable of withstanding the weight of the aviation case and its internal equipment. They will not be damaged or deformed even after long-term use. Additionally, the Euro-style wheels have flexible steering, enabling users to easily move the aviation case to the desired location, greatly improving efficiency and making equipment transportation much more effortless.

III. Robust and Durable Thick Aluminum Panels with Superior ProtectionThe main body of the aviation case is constructed from thickened aluminum panels, which are not only of high strength and good toughness but also possess excellent corrosion resistance. These thickened aluminum panels can effectively withstand external impacts and pressures, ensuring the structural integrity of the aviation case even in harsh transportation conditions. Compared to ordinary materials, the thickened aluminum panels offer superior protective performance, providing better protection for the equipment inside the case against accidental damage from collisions and compressions. Additionally, the lightweight nature of aluminum panels ensures that the aviation case remains easy to carry and transport without adding excessive weight, while maintaining its robustness. IV. Refined Plywood Design for Meticulous Equipment ProtectionThe internal plywood design of the aviation case is extremely refined, with thicknesses of 9mm for line array equipment and 12mm for subwoofers. This differentiated thickness design takes into account the specific fixing requirements of different types of equipment, providing stable support and protection for various devices. The 9mm-thick plywood is suitable for line array equipment, ensuring that it does not shake or shift during transportation, thus preventing damage caused by equipment collisions. The 12mm-thick plywood is specifically designed for large equipment such as subwoofers, with its higher strength and stability better able to support the weight of the subwoofers and provide more reliable fixation. Moreover, the material and manufacturing process of the plywood have been carefully selected and treated, with a smooth surface that will not scratch or wear the equipment, further enhancing the protective effect on the devices.

V. Reinforcement of the Bottom Plywood for Enhanced Stability
The thickness of the bottom plywood of the aviation case reaches 15mm, which further enhances the overall stability and load-bearing capacity of the aviation case. The 15mm-thick plywood has good strength and toughness, effectively distributing the weight of the aviation case and its internal equipment, making the case more stable during placement and movement. The reinforcement of the bottom plywood not only extends the service life of the aviation case but also provides a more reliable foundation for equipment storage and transportation. During transportation, even if there are bumps or vibrations, the bottom plywood can effectively absorb the impact force, reducing the impact on the equipment inside the case and ensuring the safety and integrity of the equipment.
