Using for guide stem

 

When spring without using guide stem ,according to the condition of mold spring ,there will be no stability and bending ,Using inner guide stem is the best choice.

 

>.When using inner guide stem,

Guide stem diameter should less 0.1mm than inner diameter for mold spring

 

>.When using outer guide stem

Guide stem inner diameter should increase 1.5mm than mold spring outer spring

 

>.When using one guide stem

Guide stem diameter should more than 0.15mm than spring outer diameter

 

>.In practice,guide stem should more than pedestal

Guide stem height shoulg higher a half than free length of mold spring .It can increase service life.

 

>.Mold spring only use for compression ,except extension ,torsion , or will be bending .transforamtion and scrap ,etc.
