powder metallurgy piston

Our company has more than five years of experience to produce powder metallurgy pistons. The pistons 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. Our company has advanced manufacturing equipments and precision test apparatus. The products have passed the Test center, Shang hai Plastic Research Institute. As soon as we get the new samples, we will send them to shanghai to have a test. If the test result is not as good as we anticipation, our technic team will have a meeting and discuss together, until we solve the problem. So we always tell ourselves "don't stop learning!" The annual production capacity can reach 10 million piece. The spec of our current pistons are: D20 /D25 /D27 /D30 /D31 /D32 /D35 /D36 /D40 /D45 etc. We can design and produce the powder metallurgy pistons according to the customer's demand. Here is the physical properties of our products: Tensile strength≥23N/mm2Carrying capacity≥15N/mm3Working temp.-80°C to 260°CFriction coefficient(dry)≤0.16μFriction coefficient(oil)≤0.05μ Materials: PTFE+BRONZEPTFE+BRONZE+ACID TREATMENTPTFE+CARBON FIBERPTFE+GLASS FIBER+INTENSIFIEROTHER FILLERSYou can choose the material above to design your products.
