Plunger is mainly used for aluminum, magnesium alloy die-casting, is the main wearing parts for horizontal cold chamber die casting machine.
The advantage:(1) Good wear resistance and long service life. (2) Not sticking with steel pressure chamber, Not damaging the pressure chamber. (3) Full beryllium copper material, with the whole solution, aging treatment, so the hardness is the same inside and outside. (4) Cobalt beryllium copper does not react with the magnesium alloy, is the uniquely suited punch for magnesium alloy die casting machine;
The advantages of our products:Our companya s beryllium copper punch, have a better hardness, density and wear resistance than peers. Guaranteed the hardness of HRC40 degrees above, I 100mm below generally have the availability around 10,000 die times, I 100mm above generally are available from 3000 to 5000 die times, with more than 30% of the higher life time than other manufacturersa similar products.
