PUSHPAK ERW / CDW Precision Tubes are produced at our state- of- the- art manufacturing plant that has the capabilities to produce high quality tubes at low cost and with short lead times.


Our CDW Tubes are suitable for a wide variety of applications since they have several special characteristics such as:

PUSHPAK offering ERW/CDW Precision Tubes, which are widely used in making shock absorber, gas spring applications,
  • High precision dimensional tolerances.
  • Higher strength.
  • Controlled uniform mechanical properties.
  • Smooth surface finish - 0.2 Ra for cylinder bore quality.
  • Uniform sectional thickness.

Various steps in the manufacturing process accord our CDW tubes all the desired characteristics:
  • Annealing and Surface treatment of ERW tubes.
  • Cold swaging/push pointing operations for preparing pointed ends.
  • High precision close machined die to control outer diameter.
  • Plug placed coaxial with outer die to control inner diameter.
  • Annealing, straightening, 100 % eddy current testing ensure quality and fitness for required application.
