There is no general oily lubricant pollution
It does not affect the materials negatively for painting or coating
As usual crucible normal service life is more than 6 months;if the environment and mainnentance is good;crucible service life will be longer
Adopt Mircro alloy principle to adjust the iron components,which could improve plunger head abrasion resistance and service life
Its inner hole has been ground and measured by three coordination measuring apparatus,which can guarantee the high precision in dimension.
Made of high temperature and corrosion resistance casting iron;the normal service life is longer
Gooseneck:it is made of special alloy material so that the compactness and strength can be enhanced greatly for the purpose of durability and long time.
Made of high quality electric heating wire with resonable power distribution,which can ensure the gooseneck heated evenly with stable temperature.
Made of high quality electric heating wire with reasonable power distribution,which can ensure nozzle body heating evenly with stable temperature.
Made of high quality hot working steel,quenched under high pressure in vacuum to ensure even hardness and long working time
Made of good quality material and quenched in vacuum to esnure even hardness and high corrosion resistance
