The Aluminum tubes are made by extrusion as illustrated below

The extrusion is a hot process where : |
|
|
|
- Dimensions variation is large
- Less than 1mm thickness is difficult and commercially not affordable
- Surface finish is not good
- Need artificial ageing to achieve desire strength for non-heat treatable alloy
|
|
|
|
To overcome these extrusion process limitations, SIDDHI GROUP has developed cold drawing process which gives :
|
|
|
|
- Excellent surface finish
- Very close dimensions tolerances
- Small diameter and thinned wall tube
- Added mechanical properties
|
|
|
|
Small diameter and thinned wall tubes are used for : |
|
|
|
- Mopping Equipment Handle
- Luggage Strolley Handle - Telescopic
- Button casting rod
- Heat exchanger
- Exhibition display system
- Blood bag sealing ring
- Precision turned components
