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
