Technology Used For Hydroformed Bellows Manufacturing In India

We are Manufacturer, Supplier, Exporter of Hydroformed Bellows and Our set up is situated in Pune, Maharashtra, India.

• The hydroforming machine is designed by US Designers and has been manufactured to international quality standards. 
• Hydroformed Bellows by hydroforming process are uniform in structure with adequate dimensional accuracy.
• In a single step, corrugations are formed on an entire metal bellow, which increases the productivity considerably.
• The properties achieved by the hydroforming process are far superior as compared to mechanically drawn bellows.
• Metal bellows can be manufactured with a single ply or multiple plies with excellent flexibility, pressure tightness, and little wall thickness 
  reduction.

Technical Specification:

1. Diameter Range          mm          15 - 600
2. Ply Thickness              mm          0.2-  4
3. Tube Length                mm          up to 1000
4. Internal Pressure         mm          up to 340
5. Total Power                 HP           25
6. Forming Time             Sec           <60

MECHANICAL EXPANDER

• Metal bellows with diameters ranging from 90 mm to 1500 mm (New Machine is in development for bellows up to 6000 mm) can be processed on our Mechanical punch forming machine (also known as Mechanical Expander) which is also designed by US Designers.
• Single corrugation on the bellow is being formed mechanically.
• It’s a two-step forming process, the first step is to form the tube into convoluted shape and the second step is the re-rolling process.
• The convolutions are punched individually thus eliminating thinning of bellow material.
• Metal bellows can be manufactured with a single ply or multiple plies. Internal and external diameters can be aligned as per customer’s requirement.

Technical Specification:

1. Diameter Range          mm          90 - 1500
2. Ply Thickness              mm          <3 (Single Ply), 5 Plies (1mm/ply)
3. Tube Length                mm           <1500
4. Total Power                 HP             7.5
5. Forming Time             sec             <60
6. /convolution

TESTING CAN BE CARRIED OUT LIKE:

• Radiography test.
• Fatigue test
