Are you considering purchasing a plastic extrusion line? If so, then you are probably curious about this style of manufacturing and what it entails. Here are some answers to frequently asked questions about plastic extrusion lines.


7 Faqs about Plastic Extrusion Lines

What is the main raw material for the plastic extrusion lines?

There are many varieties of plastic extrusion lines, but they all have one thing in common: the raw materials used. Plastic extrusion lines are used to make pipes and profiles. The plastic is heated to a liquid state and then pressed through an extruder to form a shape. The extruder is essentially a large screw that turns the liquid plastic into a solid object.

The most common materials for plastic extrusion lines are polyethylene (PE), polyurethane (PU), and polypropylene (PP). Polyethylene is a popular choice because it is inexpensive, lightweight, and durable. It is also easy to mold, cut, and weld. However, PE has poor resistance to chemicals, acids, and oils.

Polyurethane is stronger than PE but has poor weathering resistance. This makes it a good choice for indoor applications such as furniture or window frames. Polypropylene has excellent resistance to acids and alkalis and is highly resistant to heat degradation. It also has good chemical resistance and can be used for outdoor applications such as garden hoses or building construction.


What kind of materials can be used in a plastic extruding line?

This question is not easily answered because there are so many different kinds of materials.

The most commonly used plastic is Polyethylene, but that too comes in many grades and types. Some are very flexible while others are rigid. Some melt at very low temperatures while others melt at very high temperatures.

Some plastics are transparent while others are opaque. Some plastics can be colored (and pigments added) to make them whatever color you wish to have. Other plastics can not be colored and it's impossible to add pigments or dyes to them.

I've worked with many kinds of plastics over the years and in my opinion, the best plastics to extrude are Polyvinyl Chloride (PVC), Polystyrene (PS), Acrylonitrile Butadiene Styrene (ABS), Polyethylene Terephthalate (PET), Polypropylene (PP), HIPS (High Impact PS), Polycarbonate (PC).


How does a plastic extrusion line work?

The plastic extrusion process is the most common method for producing plastic parts, and it's probably best understood at this point. I have seen a lot of people seeking advice on how to start with a project or having difficulties because they don't really understand what they need to know to begin.

So here is a simple explanation of the plastic extrusion line:

The process of making plastic products from melted materials is called plastic extrusion. It is by far the most common way to make plastic products. The extruder is simply an electric motor that rotates and drives a screw inside a barrel. The screw pushes the raw material into the barrel and melts it as it moves forward, under the action of heaters around the barrel.

At the end of this screw, you will find a die: Think of it like a mold that shapes your product's cross-section. Molten polymer comes out of the die, forming your product in its final shape. A cooling system is used to harden and solidify the product during its exit from the die.

Most of these processes use vacuum systems when necessary to remove air bubbles, which will eventually result in defects in finished products.

Anyway, a plastic extrusion line is a machine used to process plastic materials and then turn them into various useful products.

It usually consists of a single screw extruder, an extrusion die, and a vacuum calibration tank.

The extruder drives the plastic material through the nozzle to form different shapes of plastic products.

What are the main applications for plastic extrusion lines?

Plastic extrusion line is a continuous production process of melting plastic and extruding solid, hollow, and foamed products by different forming molds. In general, the plastic extrusion lines are composed of a single screw extruder or twin-screw extruder, die head, calibration unit, haul-off unit, cutting machine and stacker, etc.


There are mainly 4 applications of plastic extrusion lines:

Pipe Extrusion Line: to produce various types of pipes like water supply pipe, sewerage pipe and gas pipe, etc.

Sheet Extrusion Line: to produce thin sheets that can be used as packaging materials in the food and medical industries.

Profile Extrusion Line: to produce PVC profiles for doors and windows with different molds.

Wood Plastic Composite Profile Extrusion Line: to produce composite materials usually used in outdoor decking.


What Are The Most Commonly Used Plastic Extrusion Lines?

The commonly used extrusion lines are the following:

Single screw extruder, conical twin-screw extruder, parallel twin-screw extruder, counter-rotating double-screw extruder.


The most commonly used plastic extrusion lines are the following:

1.single-screw plastic extrusion line
2.twin-screw plastic extrusion lines

A single screw extruder is the most common application. This type of machine has a single screw that rotates inside a barrel to heat and melts the plastic material. The screw forces the melted material out through a die, which shapes the product into a solid shape.

Twin-screw extruders have two screws that rotate at high speeds to generate frictional heat as they melt and mix the plastic materials in their barrels. These machines are much more flexible than single screw models because they can be used for several different applications such as mixing, compounding, coextrusion, and pelletizing.


How To Choose A Good Quality Extrusion Line Manufacturer?

There are a lot of manufacturers that offer the same products, so it's easy to get overwhelmed with all the options.

The price of the plastic extrusion line is very competitive in this marketplace. The price varies according to the features, quality, size, and other factors of the machines.

It is important to find out all details about the manufacturer before buying the machines. You should check out the company's profile and read reviews about its products and services before purchasing them. This will help you decide which one is best suited for your business needs. There are many companies that offer good quality machines at affordable prices but they may not be able to provide you with good service after-sales support.


Here are some tips on how to choose a good quality extrusion line manufacturer:

1. Find a reputable company that offers high-quality products and services.

2. Look for companies that have been in business for several years.

3. Ask about their experience in the field.

4. Look for testimonials from previous customers.

5. Ask if they have any references for you to contact.


How Much Is The Plastic Extrusion Line?

The price of a plastic extrusion line is determined by many factors. It's not as simple as saying that it costs 1,000,000 yuan to buy a 1,000-ton extrusion line.

The first thing to decide is what kind of products you want to make and how large the capacity of the extrusion line needs to be in order to meet your needs. Then you should decide whether you need a single screw or twin-screw extruder. This is because the two kinds of machines have different prices and completely different lines.

In addition, the pipe material has many types, such as wood-plastic composite materials, PVC materials, PE materials, and so on. Different materials use different screws, barrels, and dies for processing equipment. The price of these accessories is also different.

Finally, when choosing equipment manufacturers, there are many factors that need to be considered because different manufacturers have different equipment quality and service levels. The price will also vary widely.

The cost of a plastic extrusion line varies greatly depending on what type of plastic you want to produce and how much you want to produce. The price of a plastic extrusion line usually ranges between US$100,000 and US$1,000,000 (including labor costs) but can cost much more depending on your requirements.
