Report - Industrial Visit-

Industry number 1 (Bombay Rayon Fashion Ltd)-
The first industry we visited on our industrial visit was Bombay Rayon. This industry produced products such as fabrics and apparels. Rayon is one of the most peculiar fabrics in commercial use today. Rayon is a manufactured regenerated cellulose fiber. Because it is produced from naturally occurring polymers, it is neither a truly synthetic fiber nor a natural fiber; it is a semi-synthetic or artificial fiber. Rayon is known by the names viscose rayon and art silk in the textile industry. It usually has a high luster quality giving it a bright sheen. Coloured rayon is bought by the industry from its suppliers. Then workers at Bombay Rayon use a loom to weave the cloth. Firstly the thread is a fixed in a position. Two workers usually work on the thread placing process. This is a time consuming process which takes 7-8 hours. After the thread is set in place weaving takes place. It is done by intersecting the horizontally placed threads with the vertically placed threads. The pattern to be printed is decided by the designers who are placed in Mumbai and forwarded to the workers at the factory. A card shows the design and the length and breadth to be kept while stitching a cloth. Thus by this process the cloth becomes ready.

Industry number 2- (Neelkamal Plastics)
After Bombay Rayon the second industry we visited was Neelkamal plastics. Neelkamal plastics basically manufacture plastic chairs, tables and containers. The technique used in making plastic products is blow molding. There are various types of molding out of which injection blow molding is used by Neelkamal plastics. The process of injection blow molding is used for the production of hollow glass and plastic objects in large quantities. The molten plastic is injecten molded around a core inside a parison mold to form the hollow parison. When the parison mold opens, both the parison and core are transferred to the blow mold and securely clamped. The core then opens and allows pressurized air to inflate the parison.
There are four components used in the making of plastic. Masterbatch (Used for colouring plastic), plastic granules, material which holds the plastic together and the waste of every chair made is also added by cutting small pieces and adding it to the mixture.
There are quality checking techniques which include throwing the chair from a height, keeping weight on the chair, pushing the seat of the chair back etc. There are quality checking techniques for checking the quality of plastic boxes also which include throwing the box filled with bottles from a height, keeping bags filled with sand on the boxes etc. All these quality checking measures are applied to each and every batch and if a chair from the batch passes the check the batch is accepted for dispatchment.
The company comes up with new designs every year and the designs which are currently sold in the market are also sold along with the new designs.
This concluded day one of our industrial visit.

Visit at the rural market at Khanvel-
On the second day we visited the local market at Khanvel. We interviewed the vegetable and fruit seller, a lady selling fish as well as a person selling FMCG products.
The questions asked to them were basic, such as from where they purchased the vegetables, how much does it cost, what is their profit margin, what do they do with the stock left with them at the end of the day etc.

Industry number 3 (Sterling Generators)-
After the market visit we visited Sterling Generators. A small introductory video was shown to us before entering the industry). Shapoorji Pallonji & Co. Ltd. one of the largest Construction Groups in India, made a successful entry in the Power Generation industry in 2005 with its premier range of Diesel Generator Sets, being manufactured in one of Asia’s largest integrated Diesel Generator Sets Plant in Silvassa, under the Brand name Sterling Generators.
Sterling manufacturer generator sets from 250-3000 KVA (kilo volt ampere).
The process in making a generator is as follows:
1. Fabrication-
All sheet metal processing like cutting, bending, punching etc. are done on world-class high accuracy CNC Machines. The sheet metals are carried to the point of processing on wheeled trolleys from point of stacking. They source all sheet metals directly from the manufacturer so as to receive a quality product. After completion of the fabrication work, the processed sheet is transferred to the paint shop for further processes.

2.Painting Procedure-
Following painting process is adopted for sheet metal enclosure and all fabricated metallic part of the Panel.
Fourteen tank processes are used for pre-treatment of metal surface followed by Powder Coating, which is baked in an oven.

The pre-treatment consists of:
a.Knockout Degreasing

b.Degreasing
This is basically a metal cleaning process where removal of grease, oil, soils, lubricants, oxide films, heat treatment scales etc. are taking place before protective coating.

c.Rinsing
After degreasing a rinsing process is carried out to completely wash out the degreasing chemical from the metal surface.

d.De-rusting
This process is carried out to remove heavy rust and soil. It is carried out in the tank using mixed acid at room temperature for about 10-15 minutes. This solution is capable of arresting the fumes, while reducing the attack and removing the traces of oil. Once again rinsing is done.

e.Activation
After rinsing, the surface of the sheet metal is activated with proper Zn & Mn phosphate coating at ambient temperature.

f.Phosphating
Phosphating produces a smooth, compact, uniform zinc-nickel phosphate coating. It is a room temperature zinc phosphate process. The dip duration is around 20 minutes. Again rinsing is done.

g.Passivation
In order to obtain maximum corrosion resistance over phosphate coatings, it is necessary to apply a post treatment in order to seal the pores. This is a chromate rinse carried out at room temperature.

Dryer - 1
Components are dried in hot air chamber.
After the final process, metal is powder painted within 24 hours.

Dryer – 2

The last industry we visited was Voltas.
Voltas manufacturers cooling systems for various companies.

A chiller is a machine that removes heat from a liquid via a vapor-compression or absorption refrigeration cycle. This liquid can then be circulated through a heat exchanger to cool air or equipment as required. Heat exchanger is a piece of equipment built for efficient heat transfer from one medium to other. A gas compressor is a mechanical device that increases the pressure of a gas by reducing its volume. Compressors are similar to pumps: both increase the pressure on a fluid and both can transport the fluid through a pipe. As gases are compressible, the compressor also reduces the volume of a gas. Liquids are relatively incompressible; while some can be compressed, the main action of a pump is to pressurize and transport liquids.

This concluded day two of our industrial visit.

Conclusion -
Industrial visit provides the students a chance to see and experience how the industries work and function in reality and how that functioning of the industries be applied to the classroom learning. That is very useful in the program learning outcomes process. It enables educational institutions to build close ties with industrial experts and also to achieve the learning outcomes to students. Several broader leanings have emerged as a result of this visit.
More over students will gain the subject learning outcome by means of pre, after and post-industrial visit. This has resulted in enhanced visibility for the students among their learning outcomes and their portfolio.
