First , we should know about moulding. What is moulding?A hollow container used to give shape to molten or hot liquid material

when it cools and hardens. It is called moulding.

At Dawlance, In moulding department, it has 52 machines which are

converting the raw material of plastic to usable material of plastic. Itsharpens the raw material of plastic named as PP stands for POLYPROPYLENE. At the stage of raw material PP(poly propylene)shapes like crystals somewhat or like small crystals of sugar. Themoulding machines have large thermal injectors which melts the rawplastic and then it goes through the moving coupling plates.

There are 2 types of plates

Static plates which grips the plastic.

Moving plates who give the shape to the molten material by moving.

In steel metal department, we observe there is nothing for us.All the machines there were working mechanically . therewas nothing special to electronics. But let us tell you aboutthe process being perform there by the machines. Heavy

metal sheets were cutting, organizing in proper shapes andthen forwarded to welding and shearing section where theorganized sheets combine to form a proper metal body.This body then forwarded to coloring department. All the

process there were mechanical only in welding departmentthere was a PLC fixed which is controlling the heavywelding machine. PLC is a programmable logicalcontroller used for electromechanical work.

CNC stands for computerized numeric controller . It is heavilyused in many industries for cutting, bending and to take otherwork like it. It is controlled through a digital computer in whichprogramming is fixed by the vendor ( company from where

CNC is made). This programming may be changed or may notbe changed. It depends on the type of company policy and ourrequirements and our real case scenarios. The computer withthe CNC machine is not a general purpose computer. Its aspecial purpose computer only used for controlling the CNC

machine. Like other big industries dawlance also has a CNCused for 3D cutting of aluminium metal to make hooks to clipin the refrigerator outside to close and open the door.

P INTING SHOPAt painting shop, we saw the coloring of metal sheets in a large

furnace. It is a very big process. Firstly, the metal sheets inorganized shapes come through conveyor belt and then it gothrough the furnace. In furnace, first of all a chemical namedmeta phosphate strikes on the body through small guns and

then water strikes on it ahead to clean the metal sheet ormetal body. The metal used is aluminium. Then a personcleans the body and then it directed towards color section.Small color guns are fitted there for coloring and a personwere also there to check whether the coloring performed by

the automatic machines is doing its work properly. Aftercolor, this body forwarded to dry place where thetemperature is almost from 150to 200 where the colordried and transforms to a shiny surface as like a crystal.

After the process of coloring, the metallic body forwarded toliner department where the workers fixes the liners to the

metallic body manually. The body placed on the conveyor

and the conveyor is moving very slowly at the speed of

1m/s after a very short delay. The workers work very fastly

as they miss somewhere the entire production gets

interrupted. Liner is a plastic body fixed inside the

refrigerator outfit. Mostly, it is white in color due to

pigmentation.

HANGER 1In hanger 1, there was only the fixing of cooling lines inside

the refrigerator. These cooling lines look alike copper tubes

but in real they are not made up of copper . These tubes

composed of another material which transfers the coldness

of freezer of fridge to the lower part of it. This work also

performed by the workers manually.

HANGER2Hanger 2 is the next part and area of hanger 1. In

hanger 2, the process of foaming is performed withthe help of heavy electrical and mechanicalmachinery. It is a hazardous area and workers kepttheir selves aware of any mishap .

As from the name assembly, a image come through our mindthat what the meaning of assemble ? Hmm.. Its means to

collect the fragmented components . Like its mean it is

quite similar to its process. At assembly line, all the

fragmented components of a fridge/refrigerator align to fix

here like compressor and gates of fridge etc. and here the

entire process of refrigeration completed and the fridge is

ready to send to other distributions and other traders.
