Product Features
Excellent Corrosion Resistance Sipta's galvanised sheets possess excellent corrosion resistance which is achieved by applying a special coating of Zinc and Zinc alloys. This is further enhanced by giving a
special chemical treatment on the zinc-coated surface. This prevents the formation of white rust. Zinc Adherence
The zinc coating is so perfect that it does not peel off even under the most severe forming operations and this is achieved by using a special manufacturing process which is an integral part of the galvanising line.
Remarkable Surface Finish
Sipta's galvanised sheets have an excellent surface with lustrous spangles. This special feature is very useful for manufacturing articles which have aesthetic value.
Formability Sipta's galvanised sheets can be subjected to severe bending and forming while maintaining high strength. As the sheet is treated in a non-oxidising special furnace before coating, complate range of qualities are produced which have different hardness for different end-uses.
Quality Assurance
As a customer-oriented Company, the focus has been on incorporating
high standards of quality. Commitment to quality is deep rooted. It was
initiated at the planning stage, when investments They’re made in
sophisticated equipment and modern quality control systems, to ensure
and maintain exacting standards of quality.
9
Quality control starts at the beginning, when the main raw material, cold
rolled steel coils, are thoroughly inspected. A full - fledged laboratory
thoroughly tests the galvanised sheets, employing sophisticated
equipment such as CO analyser, hardness tester, lock forming machine,
electronic thickness gauge and chemical testing apparatus, The galvanised
steel coils emerging as a result of state-of-the-art technology with
computerised control and stringent quality checks, carry perfect zinc
coating with good formability and excellent surface finish, matching
various international and Indian standards.
Finally, to preserve high quality, the product is securely packed to prevent
and damage during handling, transit and storage.
Precautions
Handling Precautions

2. ABOUT PLASTIC BAGS:
Terms Used by Plastic Bag Suppliers:
17
Blocking: A condition that occurs when very flat or smooth surfaces placed against
each other will adhere together. Also called “cohesion.”
Die: A mold that produces a desired shape. In blown film extrusion, the die shape is
circular.
Extruder: A pump for very thick fluids. The extruder contains a rotating screw that
mixes and melts the material.
Frostline (or freezeline): The point where molten polyethylene solidifies into a film.
Gusset: Indentations in the sides of plastic bags that allow the bag to lay flat when
stored but expand when opened.
Layflat Form: Tubular poly film that’s been flattened for rolling and further
processing.
Nip Rolls: Two motorized rolling pins at the top of the cooling tower that pull the
poly film upward.
Polyethylene: A type of thermoplastic resin made by altering the molecules of
ethylene gas.
Plastic bags, also called “poly bags,” are one of those modern conveniences we take for granted. But 60 years ago, no one ever considered the question, “Paper or plastic?” Back then, people also managed to get by without Ziploc® bags or dry cleaner bags. This was because the technology for creating polyethylene film didn’t emerge until the 1940s during World War II. And the methods to create plastic bags from polyethylene film weren’t developed until the 1950s.
The most common way to produce poly bags is by blown film extrusion, also called the “tubular film process.” In a moment, you’ll see how it got this name. Plastic bags are made from polyethylene. During processing, the polyethylene might be treated with any number of additives, such as:
� Anti-block-Prevents the plastic layers from sticking together (blocking). � Slip-Helps the plastic bag open easier and allows items to slide in smoothly. � Ultraviolet Inhibitor (UVI)-Protects the plastic from ultraviolet radiation, which can weaken the plastic’s strength and fade its color. The polyethylene arrives at the plastic bag manufacturing facility in pellet form, referred to as resin.
18
The following drawing shows how plastic bags are created. The machine used to create the plastic bags is an extruder and die assembly.
3.MANUFACTURING OF PLASTIC BAGS: Blown Film Extrusion Process for Creating Plastic Bags:
1. The machine operator pours the polyethylene resin into the hopper.
2. The hopper feeds the resin into the extruder. 3. Heating elements and the turning of the extruder screw melts the resin into molten form and forces it through the extruder. 4. The molten poly flows evenly up and over the circular die.
19
5. As the molten poly emerges from the die, the machine operator: a. Grabs it wearing protective gloves. b. Pinches the molten poly together. c. Ties a rope to the top of the molten poly. The rope leads upward to a pulley system. d. Pulls the other end of the rope to move the molten poly upwards. At the same time, the air ring blows cool air upwards, which solidifies the molten poly. 6. As the tubular shape moves up, the machine operator inserts an air gun through the poly film to blow in additional air. This step is repeated until the diameter of the tubular poly film reaches the required bag size. 7. Along the length of the tower are guides to keep the tubular poly film from shifting. As the film reaches the top of the cooling tower, the guides gradually flatten it into a layflat form. If the plastic bag will have gussets, special frames (called “gusset boards”) indent the sides of the tube before it is flattened. 8. At the top of the cooling tower, motorized nip rollers grab the solidified poly film. The nip rollers now take over the job of moving the poly film up the cooling tower. Note: Extruder and die assembly towers can be 25 to 35 feet tall. This height is needed to cool the polyethylene film before the layers are flattened together. 9. The layflat film travels over a series of rollers. For simple bags, such as trash bags or industrial bags, the film is contained to a single, in-line process. In this case, the polyethylene film: − Travels through a bag machine that seals the bottom of the plastic bag and perforates it at the same time. The perforation allows the bags to be easily torn from the roll. − May also travel through a separator that breaks the perforations and stacks the poly bags on top of each other for bulk packaging in a box.
10.For poly bags with complex features (for example, multi-colored printing, Zip-Loc® closure, or door knob hang holes) the film is wound on a roll and then taken out of line for further processing at converting facility. A converting facility has a variety of specialized equipment to create the diverse features found in plastic bags today. The blown film extrusion process for creating poly bags hasn’t changed much over the years. But what has changed is how we use plastic bags in our daily lives – whether we carry home groceries in “T-shirt” plastic bags or seal an expensive cut of meat into an air-tight freezer bag. What was once a novelty is now an everyday convenience that makes our lives easier.

Bag Cleaning Machine
43
All the bags (e.g., FIBCs etc.) supplied for applications involving direct contact with articles of
food/pharmaceuticals should be free from any contamination. There should not be any
loose threads or other foreign particles in the bags. But the nature of manufacturing of
these bags is such that loose contamination cannot be fully avoided. It becomes imperative
to pass the finished bags through an automated cleaning process. Automatic bag cleaning
machine ensures efficient removal of loose particles. The draft of pre filtered air is blown
into the bag so that all the dust and foreign particles settled in the bag should come off the
bag surface. The foreign particles are sucked and collected in the dust collection box. Easy
access to the dust collection box provides periodic inspection and emptying of the dust
collection box itself. The machine is suitable for cleaning bags in height range of 1000 mm to
2500 mm

5. CONTROL PANEL
Control panel is a cabinet which contains electrical components to control the motors and equipments. Control panels are used in virtually all manufacturing environments and are an integral part of any automation or process control system. With the use of programmable logic controllers (PLCs) and network communications, components such as variable frequency drives and other input/output (I/O) devices can be distributed instead of being centrally located in a single control panel. Network cabling and distributed controls help simplify panel design and can result in reduced panel space and operational costs. Because of the demand for interoperability, and the need to share data and monitor systems more thoroughly, industrial Ethernet is becoming more common in industrial automation and process controls. The ability to control, monitor, and troubleshoot the process directly through a terminal or an Internet browser, from any location, can provide significant cost savings and improved manageability.
45
CABLES : Cables are used for the interconnection. Two types of cables are used:
Power cables (which is used to connect the motor to panel component and
panel to main supply)
Control cables (which is used to connect the control circuits)
BUS BAR : Incoming supply is connected to bus bar and distributed from bus bar. It is
normally made by Aluminium.
46
MCB (Miniature Circuit Breakers): MCB is a protecting device. It is used before the
feeder. This should be selected according to the capacity of the feeder
MCCB (Mould Case Circuit Breaker): In most of the cases the MCCB used as
an incomer for higher capacity feeders for better protection
47
ELCB (Earth Leakage Circuit Breaker): The ELCB is also known as RCCB. The
device used for the protection against the earth leakage current and residual
current. It should be fixed before the incomer
INCOMER: The basic supply will connected to this incomer. It also called as
SFU(Switch Fuse Unit). It contains one handle with fuse unit. Once it is turned ON
the supply will pass to the next stage through fuse if any major fault occurs in side
panel board, it will trip and it isolate supply.
SELECTOR SWITCH: Selector is switch is used for ON/OFF purpose and for
selecting the mode of operation like auto/manual.
48
STARTERS: Starters are used for starting the motors safely. Mainly two types of
starters are there. DOL starters and Start to delta. Dol starter is enough for the
motors with power less than 10 hp.
OVER LOAD RELAY: Over load relay is for the protection of motor from the over
load. It senses the load current and trips if it exceeds the limit. Current limit has to
be set manually. It should be 80% of the full load current.
49
TIMER: Operation of timer is similar to relay. But a delay is there for actuation. We
can set the time delay manually according to our requirement. It is very much
essential for start to delta conversion.
CONTACTOR: Contactor is an essential component in the control panel. It actuates
when the signal from the controller (PLC, Relay logic) comes. It is similar to relay. It
is costlier than relay. It is used for a higher load.
