Due to the R&D capabilities, manufacturing levels, differences in test conditions and blind configuration comparison of various oversized ceiling fan manufacturers, there is a tendency to compete to improve the marking of aluminum alloy profiles.
As a product that is closely related to safety, ensuring safe use is an undoubted prerequisite!
The question is, is the higher the aluminum alloy designation, the safer?
Taking the most common blade accidental fall in the daily use of the oversized ceiling fan and the blade being hit by external force as an example, higher aluminum alloy material marking means higher strength and hardness, in the event of external force collision, the blade may not fall or damage because of thickening, equipped with stiffeners or high-grade material, but this means that the energy generated by the collision is rigidly transmitted to the hub, motor, and even the roof load-bearing beam, and the resulting hidden dangers are clear at a glance compared with the blade damage.
The blades of Hengzhengtong's oversized ceiling fan are stamped from aluminum magnesium alloy sheet of type 5052. Due to the unique shape of the blade and the shape of the inner cavity, sufficient support strength can still be formed without additional thickness of the blade material or built-in stiffeners to ensure that the tip of the blade will not sag and bend. In the event of external impact, the blades are deformed because of the relatively soft material, which effectively absorbs the collision energy, and combined with Hengzhengtong's unique wheel hub vibration isolation rubber sleeve, it effectively protects the motor and building structure.
Hengzhengtong hub parts, petiole parts are made of 6061-T6 material, in order to confirm the safety and reliability of material and component design, according to the short board theory, the weakest special-shaped slip hole parts and blade thin plates are selected, and sent to the Metrology Research Institute under Shenzhen Bureau of Technical Supervision for destructive tensile testing, and the results prove that the safety of component materials and designs far exceeds the safety limits of general mechanical products.
