Good seal steam treatment D30 multi-lip TFM banding Shock Piston with material of Hoganas powder


We are engaged in developing and manufacturing different kinds of shock absorber pistons powder


metallurgy based, with PTFE or TFM material banding outside, they have advantages of low friction, good


seal properties etc.


As a modern company orientated towards organic growth it is in our interest that there is a team-spirit,


that everyone is reliable and that we are all following the same targets. Our highly motivated and


competent team can be depended upon to pursue the utmost aim of the company which is "customer


satisfaction" at a consistently high quality.


We have different testing machines such as abrasion testing machine, tensile strength testing machine,


density tester, hardness testing machine and so on. We also design and develop a special testing


machine which test blow-off of banding piston.


The products have passed the Test center, Shang hai Plastic Research Institute. We have set up good


cooperative relationship with some big shock absorber factories home and abroad. Our mass production


piston types are: Φ20, Φ25, Φ27, Φ30, Φ31, Φ32, Φ35, Φ36, Φ40, Φ45, Φ50.


SPEC: D30.05XD8X11.5
