INTRODUCTION

This report gives information on topic about manufacturing of MCB boards. A MCB has

three parts.

1. Inner part

2. Outer part

3. Box

In this report we will study about the manufacturing of inner part only. Various

manufacturing operations like cutting, bending, blanking is done on power press machines to

produce the inner part. After cutting and bending some labor work should also be done on the

inner part to improve its accuracy and remove or minimize the discrepancy. There are various

types of power press available to produce the desired part. The power presses available in the

manufacturing unit are as follows.

1. Power press (PP1) it is of 5 tons.

2. Power press (PP2, PP3, PP4, PP5) They all are of 10 tons.

3. Power press (PP7) it is of 20 tons.

4. Power press (PP8) 30 tons.

5. Power press (PP9) 50 tons.

Here the aim of the work is to study about the processes occurring in the manufacturing unit,

time consumed in their manufacturing, the material required and how to improve the

production.

The work presented in this report will give us a picture of production unit of the industry and

will highlight the problems which have a serious impact on the production.

PRESENT INVESTIGATION REPORT (15 DAYS)

In this 15 days report we are going to learn about the manufacturing of inner part of MCB

board only.

First step in the process is import of raw material i.e. Galvanized iron sheet of uniform

thickness of 1mm, which are of specific lengths and breadths.

Thin sheet which is used as raw material.

Stack of raw material.

Second step is cutting and punching of sheets to form the appropriate shapes.

Third step is the bending of sides of the sheets to form the inner portion of boards. The sheets

are bend with the help of power press machines. Mostly 10 tons power press machines are

used to bend the sheets into desired shape. The sheets are bend at an angle of 90 degrees from

all the four sides. After bending some manual operations are performed on them to remove

the discrepancies in them.

The final product after performing all operations like cutting, punching, bending looks like in

the figure below.

After the extraction of finished product some operations are done manually with hammer to

remove the spaces between the two plates.

After doing manual operations on inner part its void spaces are covered and then it looks like

in the figure below.

RESULTS AND DISCUSSIONS

The inner part is produced by various power press machines mainly by 10 tons machine

which are capable of cutting, bending and punching. The sheet metal of particular sizes is

imported from local owners for the production of inner part of MCB board. It goes through

operations like:

1. Cutting

2. Punching

3. Bending

4. Removing void spaces

These are the processes which took place in manufacturing of inner part of MCB.

SUMMARY AND CONCLUSIONS

In this section we have learnt about the manufacturing of inner part of MCB board. We have

learnt about the various processes that are required in production of inner part in MCB board.

In the upcoming reports we would learn and study about the various parts of MCB boards

such as outer part, the MCB box, finishing, painting etc.
