Objective:

It is the well-known that work experience is an essential part of

every professional course. In the same manner practical training

in any organization is a must for each and every individual

engineering course. The objective behind visiting the URIL-

Dawalance and preparing the Project Report is to study the

electrical overview, mechanical overview, processes of

manufacturing and details of control and instrumentation required

in URIL-Dawalance.

We have carried out this training under well experienced and

qualified engineers and technician from various department like.

Electrical, Electronics, Mechanical, Chemical. We have taken the

opportunity to explore the Electronics Department, its use,

necessity in Dawalance industry and maintenance Processes of

Manufacturing.

We have tried our best to cover all aspects of URIL-Dawalance

and their brief detailing in this project report. All the above

mentioned topic will presented in the following pages of this

report. The main aim to carry out training is to familiarize

ourselves with the real industrial scenario, so that we can relate

with our engineering studies.

If Someone Wastes 10 Minutes Of your Time, 8 Minutes Is Your Fault….

Summary

According to our study, we were interested in manufacturing industry of

engineering specially refrigerator Industry. It was great opportunity for us

to do an internship at URIL-Dawalance. The internship concentrated on

ELECTRONICS Field and ELECTRICAL Field.

At the beginning we all set our goals. During several times visit

different Production plants and being involved in different activities, we

tried to achieve our learning goals. The objective was to study all

instrumentation and electrical part thoroughly and to know the reasons of

failure of Production Plant. Supervisor helped us a lot in making good

relation with workers over there.

At last this internship has given us new insights and motivation to

prepare ourselves for our future career, so as we can on our own skills.

After this we are feeling some motivation in our selves.

Introduction

United Refrigeration Industries Limited Dawlance also known as URIL-

Dawlance. It is one of the major manufacture Plant of our country. In this

factory the main focus on D-freezer and Refrigerator. It is located in

S.I.T.E area, Hali Road district Hyderabad

URIL-Dawlance has normal capacity of production per hour is

120 peace. It consist of main four major Production Plant which given

below:

1) Production-1 (Plastic Moulding Shop)

2) Production-2 (Shearing Sheet Metal & Welding)

3) Production-3 (The painting Shops)

4) Production-4 (Pre-Forming & Forming)

5) Quality Control Department (Q.C.D)

Pg. 4 Conclusion:

PRODUCTION-1 (Plastic Moulding Shop)

As the name suggest plastic molding the production is said to manufacture all plastic type of equipment that can be used in refrigerator manufacturing. There are 6 section in molding each have its own task to with they can act these are as follows.

1) Compounding section2) Injection section 3) Hot stepping section 4) Steam print section 5) Extrudes section 6) Cable section

Compounding section The raw material of various plastic material in the form of huge grain is received in compound portion through store room.• PS• ABS• PC• NYLONE & PP

Injection section:It is heart of moulding section here all plain parts are been manufacture through injection mould melena.The highly automated machine CLF-INJECTION MOULDING MACHINE use in this section.

Hot stepping section: It is little section in which chosen stepping is to be done over the freezer door pocket that desirable the various sign.

Extruades section: It is the of section actually injection moulding process and it is also ised to make the profile that has been mould plastic material and give the shape of profile.

Pg. 5 Conclusion:

Cabel section:

The refrigerator wire conntection from the electric reqired a plug and

cable so in the there things are to manufactured.

Once the wire cables to be purchased that first of on this cable are to

cutted the required size and then the folly steps are to be taken.

1) Core stepping

2) Wire stepping

3) Pinch foulding

4) Princh moulfing machine

Pg. 6 Conclusion:

PRODUCTION-2 (Shearing Sheet Metal & Welding)

Shearing means to shear off the requires size of sheet is called a

shearing process.

Sheet metal means the various process that has been perform ever the

metal sheet stop that give is the requires shape os to be vallled a sheet

metal.

Welding: a process of permant fastening important type used the most

important type used in dawlance is tug welding.

There are two mwthod for welding process

1. With help of co2 2. With the help of electricity

Raw- Material of Production-2 is in sheet form given below:

1) Metal steel

2) Galvanized iron

3) Vinyl coated material (VCM)

4) Alumimum

Pg. 7 Conclusion:

PRODUCTION-3 (The Painting Shops)

It is basically the painting section used to paint the various iron so that it

could be transfer into the final assembly shop.

It includes the:

1) CABENT painting shop

2) EVAPORATER painting shop

3) CONDENSOR paonting shop

4) DIP-COATING (shelf painting shop)

Pg. 8 Conclusion:

PRODUCTION-4 (Pre-Forming & Forming)

PRE-FPRMING SECTION

As the name suggest it is the pre of the forming that is it the place where

the various operation is to carry before it is to be placed to formed.

At the pre-forming the necessary item such as the liner, freezer and anti-

moisture tube, evaporator are to be inserted into the actual body cabinet.

The actual process of pre-forming is starts when the painted cabinets

from the cabinet painting shop are comes to the pre-forming zones.

FORMING SECTION

The forming section is a place when the pre-formed cabinet is to formed

by the automated machine.

The foam which is to be inserted within the pre-formed foam than it is

solidifying within a few minutes.

The foam is basically made of two different type of chemicals.

1) Polyoal 3) Iso-cynate

2) R141B (a gas which is used as a catalyst)

Basically the mixing of chemicals as to chemicals as to form the foam is

to be as:

100% polyoal , 1260% of iso-cyanides , 16% of R141B

Pg. 9 Conclusion:
