Valve Guide which guides the motion of valves should endure rapid friction with valves requiring high wear resistance and greatly improved machinability and cost.
Although casting valve guides were in general use in the past, it became changed into sintered valve guides so that it can be designed by various alloy with the tendency of large and high speed output of engine which requires high wear resistance. With the change of the material, the sintered valve guides are applied to most of the passenger cars with cost efficiency.

Valve Guide Technology

  • 1.Reliability and Quality target
    • Scuff resistance
    • Applicable to chrome & nitrided valve stem.
    • Improvement in machinability Cost efficiency
    • Quality control in measurements, segregation,
      micro-structure of material and density.
