1.Effective lubrication,the cost of lubrication is half that of other lubrication methods.

 

　　2.Less lubricant,low gas evolution,effectively reduce the inner porosity of casting(especially hydrogen stomata)

 

　　3.The residues in the solution cup can be blown away,improve the inner quality of casting.

 

　　4.Drop volume can be adjustable,no spot on the casting's surface,improve casting coating performance.

 

　　5.Fixed-point and quantitative dripping lubrication,improve the environment around the workshop.

 

　　6.Using the?xed-point spray lubrication,uniform coat and e?ective lubricating,the service life of the plunger tip is multiplied.
