2 ways to create a tank head
There are 2 possibilities to create a tank head :
- Flanging and dishing: DVAI can manufacture tank heads by flanging, following the steps outlined in the diagram below. Flanging has the advantage of achieving any dimension freely.
- Spinning and dishing: The manufacture by spinning imposes the constraint of working against a tool. All dimensions are not possible due to lack of tools or require a new particular tool, consequently this point can strongly influence the cost of each spun piece.
