порошковая металлургия поршня

XiaYi auto parts company was established in 2005. Wehave more than five years of experience to produce powder metallurgy piston. We began to research and develop such products at the beginning of the year 2000. Ourproducts can be widely used in many kinds of shock absorbersof automobiles and motorcycles. The middle part is the powder metallurgy and the outside is the PTFE material, which has the advantage of low friction coefficient, good wear resistance and so on. These kinds of products canbe usedin high temperature without any problem. Ourproducts have passed the Test center, Shang hai Plastic Research Institute and as soon as we have new samples, we will send them to Shanghai to have a test, to check the mechanical properties is ok or not. We have a complete set of machines such as full-automatic compression machines, gas shield sintering equipments, precision CNC wire-electrode cutting machines, 3D CNC electric spark machines and so on. We can design and produce the powder metallurgy pistons according to the customer's demand. Here is the physical properties: Tensile strength≥23N/mm2Carrying capacity≥15N/mm3Working temp.-80°C to 260°CFriction coefficient(dry)≤0.16μFriction coefficient(oil)≤0.05μ Lip design: No LipSingle LipDouble LipYou can choose one kind of lipabove todesign the pistons.
