    Description:


    High quality shock absorber piston, used in various cars and trucks


    Properties of banding ring can be tested in our company, we have the following test equipment:


    Tensile strength testing machine, friction & abrasion testing machine, density balance, coefficient of linear


    expansion testing machine and so on.


    We also design and manufacture non-standard testing machine which can do blow-off test after banding.


    Adhesion test: ring must be tested in shock absorber according to characteristics below:


    Piston must have a minimum diameter of groove.


    ---pressure tube must have maximum internal diameter


    ---traction force from 4700 to 5390 N and speed=1.5m/s according to condition below


    ---course =50mm


    ---frequency =574RPM


    ---moment must be applied at the end of piston rod = 3Nm


    ---temperature = 130/160℃


    Ring withstand 10min without deformation on adhesion test.


    Properties of the banding ring:


    Density = 2.03-2.110g/cm3


    Hardness = 57-61 shore “D”


    Tensile strength = 16Mpa minimum


    Elongation = 300% minimum


    Advantage of powder metallurgy:


    Unique chemical composition and mechanical physical properties


    Facility involved for material Q&C


    Chemical composition:


    Ø OBLF Spectrometer with 29 channels in bi-metal of AL+FE


    Mechanical Property


    Ø Hardness test


    Ø Mechanical property inspection


    Ø Impact inspection


    Microstructure:


    Ø Microscope Metallographic Analysis as per AQL based on heating number


    Structure tightness


    Ø Destruction test


    Ø Weight test


    Applications:


    Car or motorbike shock absorbers


    Competitive Advantage:


    1.Professional manufacturer


    2.Close tolerance and high density


    3.Uniform heat treatment and steam treatment


    4.Precise metal-working finishing


    5.Higher mechanical performance


    6. Tooling designed by XIAYI can assure the delivery date


    7. A whole set of testing equipment
