The manufacturing chain

## How it is made, in 6 steps.

The sequence Indian factories follow, from raw material to an approved part ready to ship.

  1. **Tube sourcing** ERW or seamless, steel, stainless or aluminium
  2. **CNC bending** Mandrel bending to CLR on multi-stack benders
  3. **End forming & notching**Flaring, swaging and laser notching
  4. **Jig welding** TIG on fixtures for repeatable geometry
  5. **Finish** Powder coat, chrome or passivation
  6. **Check fixture inspection** Go/no-go fixture plus CMM on first articles

Key facts

Tube bending & TIG-welded frames questions

## Straight answers.

Anything else, ask us directly. A principal replies, not a bot.

[anirudh@sourcesquid.co](mailto:anirudh@sourcesquid.co)

### Can Indian suppliers bend and weld aluminium tube?

Yes. Many bend and weld 6061 and 6063 tube, with heat treatment after welding where needed.

### Who pays for welding fixtures?

The buyer usually pays a one-time fixture cost, which gives repeatable geometry across batches.

### What finishes are available?

Powder coating, e-coating, chrome plating, and passivation for stainless steel.
