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.
