  • Q Q7: Why did I choose you? What advantages do you have?

    A Company has introduced the world’s most advanced production technology of forged of aluminum magnesium alloy wheel. and all the equipment are purchased from the international first class industry manufacturers: The CNC spinning machine of Germany LEIFELD and SBS company, the CNC machining center of Italy IMT, and the polishing machine of Spain AUTOPULIT company, and  the robot of Switzerland ABB company, as well as the automatic detection equipment of BII company of the United States, and has introduced 5 high automation production line, equipped with more than 120 sets of advanced equipment, the robot is more than 50 units, the annual output is 3 million pieces.
  • Q Q8: What are the advantages of your aluminum wheels?

    A
    1.Lighter
    Compared with regular steel wheel with inner tube, the weight aluminum magnesium alloy rim of GKZG is reduced nearly 50%.
    Compared with regular steel wheel with inner tube,the weight aluminum magnesium alloy rim of GKZG is reduced 25kg each set.
     
    2.Stronger
    Compared with the pressure needed to make the wheels happening 5cm deformation Aluminum magnesium alloy rim of GKZG-71200kg Regular steel wheel-13600kg
     
    3.More heat dissipation
    The heat conduction coefficient pf the aluminum magnesium alloy is 3 times of steel, addition,the structural feature of the aluminum and magnesium alloy wheel is easily disperse 
    the heat generated from the tire and base plate to the air
    (1) Make the car keeping the proper temperature to lower the rate of puncture
    (2) Obviously prolong the service mileage of tire
    (3) Greatly reduce the maintenance cost of the braking systems
     
    4. More beautiful
    The wheel of forged aluminum magnesium alloy wheel of GKZG is an integral forming.The surface is smooth and is handled easily.The surface has aluminum alloy metal texture. The polishing technology makes products having noble style and quality.

    5.More smoothly
    The aluminum magnesium alloy wheel of GKZG is forged by an integral forming. The roundness is less than 0.1 mm,but the roundness error of steel wheels of is in more than 1 mm; When it is full load: The average deformation volume of the forged aluminum magnesium alloy wheel of GKZG is 0.52 mm, but the average deformation volume of steel wheel is 2.24mm. The rolling resistance of the forged aluminum mangnesium alloy wheel of GKZG is small, and tire wear is also uniform, and the driving is more smooth and safe.
     
    6. More economic
    It is assumed that a car driving 300000 km, the consumed diesel oil is 126000 liters.After using the forged aluminum magnesium alloy wheel of GKZG, the oil consumption of the vehicle can be saved 6300 liters a year, that is the fuel consumption of the vehicle is saved 41139 Yuan, and the tire cost of vehicle is saved 9900 Yuan, and the additional income of more carrying cargo is 14400 Yuan, and the total saving for a single car is 65439 Yuan. 
    Note: The tire life is extended life by 15%, and tire life is fixed for the time being is 200000 kilometers.
    (the specific data shall be based on the actual measurement)
     
    7.More environmentally friendly
    Under the normal situation, when the car reduces every 100kg in weight, the CO2 emissions can be reduced 5g/km; and when the car reduces every 10% in weight, the fuel consumption can be reduced by 6%-8%. The lightweight design has become an urgent need to reduce the emissions of the transportation vehicle.
