How is the graphite packing ring made?
The graphite packing ring is made of hydraulic press and die. We make the sealing equipment and gasket
Said first want to know the filler diameter (MM) mold, should pay attention to the diameter smaller than the actual size of 0.02-0.03mm, inner diameter of 0.01-0.02MM is larger than the actual size, if the amount is relatively large, can do simple die, live fast, die has the advantages of simple process, cheap price, generally in about 1 dollars per millimeter the disadvantage is not easy to grasp, thickness, the number of small mold thickness can do, easy to master, but the price is high, heavy, hydraulic loading trouble, do not need too much, generally 25 tons --50 tons can do 400 of the diameter of the packing ring plane, 500*500, about 5000 of simple hydraulic machine, flat machine liquefied 13000---15000,
The graphite packing ring is made of a certain density graphite coil, which is mechanically cut into the mold and is made by cold pressing. It has the characteristics of corrosion resistance, high temperature resistance and self lubrication,
