Assembly line is a process in manufacturing for production of goods where smaller products are assembled at different steps in a sequence to produce the final product. Assembly line production is an important mechanism to have increased productivity and maximize efficiency of the product being manufactured.

2. What is Assembly Line?
● Assembly line is a process in manufacturing for production of goods where
smaller products are assembled at different steps in a sequence to produce the
final product.
● In assembly line production, the main product moves from stage one to the end
stage in a defined sequence.
● In most cases, an assembly line is a partial automated process, and at each stage
there might be a human intervention.

3. Importance Of Assembly Line
● Manufacturing of goods or products is a lengthy process as it requires several smaller
parts to be assembled together.
● Smaller parts when attached or assembled in a particular sequence of stages leads to
formation of the finished product.
● Assembly line production ensures that there are multiple stages defined in the
manufacturing process, and at each stage a smaller part is attached.
● Once all stages are completed, the finished product or the assembled product is
created.
● The workers at every stage at stationary and are experts at assembling their small part.
● The line or the conveyor belt is used to take the product to the next stage.

5. • Assembly line production is an important
mechanism to have increased productivity and
maximize efficiency of the product being
manufactured.
• A streamlined manufacturing process enables
workers to work in tandem at their respective
stage. Use of a conveyor belt or line ensures that
the product is taken to every subsequent stage
for assembly of the next smaller part.

6. Types of Assembly Line Methods
This process involves having parallel
assembly lines producing multiple
smaller products simultaneously.
At the end of each assembly line, all
lines or smaller products are merged to
produce the finished final product.
Modular Process Cell Manufacturing
This method of assembly line
uses machines which can
perform multiple tasks at a
single stage, rather than
having a separate stage for
every step required.
Team Production
This method involved
teams to participate at
different stages & final
quality check stages to
ensure that the finished
product is of high quality.
U- Shaped
Assembly Line
In this method, instead of a straight line of production,
there is a U shaped or curved line, where workers stand
between the curves. This ensures better communication
between adjacent stages of production.

Depending upon the arrangement, design, stages, production need etc., there are
different ways to have assembly line production processes. Some of them are:

7. Advantages of Assembly Line
● Time to manufacture goods have reduced.
● Higher efficiency of output as each stage is driven by an expert worker.
● Assembly line enhanced by concepts like JIT or just in time ensure a streamlined,
smooth & continuous flow of production.
● People management has become easier as each worker has their role clearly defined
and is unique from other workers working at different stages of production.

8. Example
• A very common and well known example is car manufacturing
where a lot of parts are assembled one by one to create the final
automobile. The process can start from engine fitting and then
the car moves to chassis assembly. From there it is moved to a
stage where the overall car body is assembled through various
operations including doors, windows etc.
• Then next step can be painting and coating the car with required
color before it moves to installation of seats and other interior
instrumentation. After that other final things can be assembled
and completed before the car can go in testing stage.
