Features:

Through the special processing technology, the microcrystallization of intercrystalline structure, lattice dislocation distortion, the density of structure increases, causes the wear resistance of metal material improved several times.

1.The nodular cast iron plungertip treated with microcrystallization has 5 times more service life than the untreated.

2.Proper selection of the tolerance range of plunger tip is the prerequisite to guarantee the service life of the plunger tip.
