Benefits of PVC pipe manufacturing machine
The PVC pipe manufacturing machines possess the following benefits:
Can manufacture pipes of different lengths and thickness just by changing the mods and dies.
Increases the productivity level.
Ease of operation and maintenance
Elimination of wastage of raw material
Basic properties of PVC
PVC is a plastic with a chemical formula CH2=CHCI. The main properties of PVC are as follows:
PVC has a great chemical inertness
High glass transition temperature
It is a thermoplastic material
Possess immense heat resistance
High heat distortion temperature
PVC exhibits a good resistance to acids and bases
Great toughness and strength

2. Ease of blending, ease of processing
Flame resistant and fire prevention properties
Introduction:
Polyvinylchloride (PVC)[-(-CH2-CHCI-)n-] is one of the three most important polymers currently used
worldwide . This is because PVC is one of the cheapest to make and has a large range of properties so
can be used to make hundreds of products . PVC is formed by the polymerisation of vinyl (choroethane)
monomer units:
PVC consists of polar whish are attracted to each by dipole-dipole interactions due to electrostatic
attractions of a chlorine atom in one molecule to a hydrogen atom in another atom:

3. These considerable intermolecular attractions between polymer chains make PVC a fairly strong
material.
Uncompounded PVC is colourless and rigid and possesses poor stability towards heat and light.
However , the use of additives/stabilizers enables us to change the properties of the PVC to how we
desire.
Disposing Of PVC :
Once the PVC products have used been they can be disposed of safely by recycling, incineration or
burial methods.
Recycling can be carried out in two ways; either by sorting the waste plastic by hand or more
recently the polymer automatically , this is known as mechanical recycling.Alternatively the
polymer can be recovered and recycled. This second method is known as feedstock recycling.
Incineration reduces the amount of PVC waste going landfill . Burning of PVC does produce toxic
gases such as hydrogen chloride but none are any more toxic then carbon monoxide and PVC
produces no more deadly dioxins than say the burning of wood . However ,the incinerators are
equipped with pollution control equipment to minimize the release of emissions to the
environment.
Landfill is carried out for the PVC plastics that can nit be recycled. Controlled landfill does not
cause significant risk to the environment
To summarise:
PVC depletes fossil reserves, and releases toxic gases and dioxins when manufacture and incineration
processes . However ,PVC can be recycled , it is cheap , is nor very flammable and has many uses some
of which have helped save lives. These later for PVC plastic outweigh the few cons by far.
Manufacturing Reports:
The national association of manufauturers (NAN) is pleased to bring you several reports that highlight
manufacturer’ agenda for boosting growth and creating jobs. In these reports,you can find key facts and
information about manufacturing in the United States, as well as important data and statistics for
manufacturers. In addition, the NAM has published a manufacturing strategy for jobs and a competivive
America that lays out the policies manufacturers need to compete in the global markerplace.
History
It is said pve- that it was accidentally discovered on a couple of occasions in the 19th Century.

4. In the early 20th century a clever Russian chemist , and a forward thinking german company , attempted
to use PVC in commercial products, but unfortunately they were unable to stabilize a processing
methos…
…what they did do though ,is lay the foundation for another copany, (BF Goodrich),to develop a method
in 1926 blending PVC ,with some other additives. This caused the material to palsticize, and the result
was an easily processed material that very quickly achieved widespread use.
How about PVC now?
PVC ,(or polyvinyl Chloride), is one of the most widely used thermoplastic polymers.
In terms of revenue generated it is one of the chemical industries most valuable products.
Around the world the construction industry alone , uses around 50% of the total PVC
Thai plastwood PVC
All plastic’s today have been improved and refined over and over- their production has diversified to suit
many different applications.
With regard to construction plastics, there is very little that plastwood do not know about PVC.
Over almost two decades, we have enhanced our products chemical make up,and combined with
our state of the art German/Austrian made machinery. we are producing some of the very best
construction plastics available. Using the very best method, the Celuka method.
Thai palstwood specialize in the manufacture of pour it back into the pan like so. Now one smooth
continuous piece of PVC pipe. There you have it, a simple way to cut and bend PVC pipe into any shape
you want.
Description:
PVC is the de-facto standard in home waste line materials. It is a strong, chemical resistant rigid
that is heat resistance and easily and cut and fit. It is often used to repair sections of broken cast iron
waste pipe.
Prevalent Use:Use for sanitary waste lines, vent pipes and drain traps.
Cutting and fitting:
PVC pipe is easily cut with a hacksaw or tubing cutter. The sections are joined together mechanically
using plastic pressure fitting for later removal or permanently joined using special chemical solvent.

5. PVC pipe machine or poly vinyl chloride manufacturing machines are specially designed to produce
superior quality PVC pipes which are used for various applications in almost all industries. These
machines incorporate a die, an extruder, cutting saw, stacker and a corrogator. Almost all the plastic
pipe machinery is fully automatic that is a relief to the PVC pipe manufacturers. These PVC pipe
manufacturing machines are capable of operating in high temperature and pressure and resistant to
corrosion and abrasion. For these features, the material quality used to make polyvinyl chloride pipe
machines is of standard.
Constituents of PVC pipe machines
These PVC pipe machine use PVC resin along with certain satbilizers and modifiers, and combine
them in pre-determined proportions, heated, pressed and fed into the extruding unit. Then, the mixed
PVC resin is poured in corrugated molds, cooled and cut into pipes. An automated sensor is used to cut
them into pipes of desired length and later stacked.
Special Features of plastis pipe meachinery:
PVC pipe making machine possess all the positive points of the original models perfectly blend with
innovative technology. These machines enjoy many different advantages including smoother operation,
reasonable structure, more compact appearance, high efficiency, easy operation and minimum
maintence. Possessing wide adaptability, these PVC pipe making machine are ideal for heavy
production. Almost all the polyvinyl chloride pipe machines are automatic and completes the work
within no time.
Different kinds of PVC pipe machime

have great air induslating property.
Plain socketing machines

6. Plain socketing machine are the PVC pipe manufacturing machines that is used for cutting PVC
pipes. This PVC pipe machine has oven with infrared or tubular heaters and to avoid thickness
reduction it is given with push and blow mechanism.
High quality rigid foam sheets and products which have many applications which include-Construction,
Signage and art and craft industries.
We manufacture our product into preformed items such as cladding, flooring, doors windows etc, as
well rigid foam PVC sheet’s.
PVC is increasingly taking the place of wood based products in the construction industry today.
Here are some PVC characteristics that you may not have previously known, as well as some that I am
sure you will:
Produced from natural substances.
It has very good heat and sound insulation properties.
Fire resistance ,(in fact will self extinguish within 5 seconds, if the source of fire is removed).
Resistant to most corrosive substances, Acid’s Alkali and hydraulic oil etc.
Can be sanded filled , printed ,laminated or painted.
Colours can be applied during the manufacture.
Resistant to insect, and fungal attack.
It can glued, jointed or welded.
It can be moulded into shapes or profile using heat.
PVC sheet has extended re-use ration in such applications of formwork/shuttering.
Does not absorb water.
100% recyclable into similar products

7. Health Issues
In recent years there has been some speculation that certain plasticizers used in PVC manufacture are
able to leach out, and there have also been health issues raised.
These plasticizers are additives used to make PVC flexible. Because Thai plastwood produce rigid foam
materials and products, these additives are required.
Recycling
One very good reason that PVC is not often recycled is because of its lifespan, once it is installed it will
last for many years.
But it can be recycled, and there are an increasing number of facilities that do just that, (we recycle all of
our waste materials).
Because PVC is a thermoplastic, meaning when subjected to heat it softens, and can be reformed to
make many usefull products.
It is a common practice to compound PVC in a twin screw extruder, than pellatize the PVC and use those
pellets in a secondary extrusion opperation to make finished goods.
