The document discusses the best way to manufacture a car exhaust by describing the tube bending process. It introduces that an exhaust removes carbon monoxide from the engine and its main function. The tube bending process involves pulling the tube over a fixed mandrel to support the inner radius of the bend as the tube is formed into the bend die, preventing kinks or wrinkles. This process provides advantages as a simple, straightforward way to bend tubes for car exhausts without flattening or need for further finishing of the bent product.

Advantages and Performance

2. Introduction
 Exhaust is an essential part of a car.
 Its main function is to get rid of carbon
monoxide and other wasted gases that is
produced by the engine.

3. Tube Bending Process
Tube being
pulled over a
mandrel held
in a fixed
position.
The pipe is
bent.
The force
acting on the
mandrel tip
supports the
inner radius
of the bend,
holding it
firmly into the
bend die.

4. Advantages and Performance
 Simple and straight-forward process.
 Prevents the tube from flattening.
 Allows a bend to be made without wrinkles or
kinks.
 Less or none finishing process is required for
the finished product.
