PVC Pipe Extrusion Machine Line

When it comes to PVC pipe production machine, there are many people with a common question:

I want to start a small setup of the PVC pipe industry. What should I do?

If you have similar questions and cannot find a satisfying answer. Read this passage!

We will help you find the answer through 3questions below step by step.

1. What is a pipe extrusion machine?

2. How do you manufacture PVC pipes?

3. What are the guidelines needed to set up the PVC pipe micro-scale manufacturing unit?

If you want to start a PVC pipe extrusion plant, you should learn about the PVC pipe extrusion machine for sale first. It is one of the most important factors you need to know because you cannot produce pipes without it.

Now let’s begin.

What is a pipe extrusion machine?

Before we learn about the pipe extrusion machine, let’s see what is plastic extrusion first.

What is plastic extrusion?

Here is a quote from wiki’s website:

Plastics extrusion is a high-volume manufacturing process in which raw plastic is melted and formed into a continuous profile. Extrusion produces items such as pipe/tubing, weatherstripping, fencing, deck railings, window frames, plastic films and sheeting, thermoplastic coatings, and wire insulation.

This process starts by feeding plastic material (pellets, granules, flakes or powders) from a hopper into the barrel of the extruder. The material is gradually melted by the mechanical energy generated by turning screws and by heaters arranged along the barrel. The molten polymer is then forced into a die, which shapes the polymer into a shape that hardens during cooling.^[1]

 

Now let’s learn about PVC pipe extrusion machine from 3aspects: application, configuration, and types.

What is the application of PVC pipe extrusion machine:

The PVC pipe extrusion machine is used to produce pipes with different diameters by replacing extrusion dies. It can produce every size of pipe in the area of the agricultural water supply system, architectural water supply system, pavement of cables, etc. It can produce the conduit pipe, pressure pipe, water pipe, drainage pipe, etc.

What is the configuration of PVC pipe extrusion machine configuration:

The PVC pipe extrusion machine is actually a series of main machines with optional auxiliary machines. (Pls refer to the table below. )So we also call it the PVC pipe extrusion machine line.

configuration table:

Now let’s introduce 6most important machines in the table in detail.

6most important machines:

1. Conical double screw extruder adopts 38CrMoAlA material screw and barrel, nitriding process. It is a special design for PVC powder extrusion. By changing the die and auxiliary machines, it can produce many products like PVC profile, PVC ceiling, PVC trunk, PVC door, PVC foam board, etc.
2. PVC pipe extrusion die is made of 40Cr, which is used to modify and shape the final products.
3. The vacuum calibration tank body is made of stainless steel. The tank is equipped with a vacuum pump and a water pump. It is used to cool and size the pipe with a vacuum environment. It works together with pipe die parts sizing sleeve to make the PVC pipe into wanted diameter and into a round shape. It can also a little adjust pipe thickness. Its cover material is cast-aluminum.
4. the haul-off machine has many models to choose from according to pipe OD like 2-claws, 3-claws, 4-claws, 6-claws, 8-claws, 10-claws, etc.  This part is used to haul the pipe at the same speed as the extrusion. Sometimes it can have the function to adjust PVC pipe thickness a little. When its speed is higher than extruder, the pipe wall becomes thinner while its speed is lower than extruder, pipe wall becomes thicker. Hauling speed is controlled by ABB inverter.
5. The planetary cutter of the PVC pipe production line is used to cut pipes into wanted length such as 3m, 3.5m length, etc. It is controlled by PLC. (Want to know how to operate cutter, click planetary cutter)
6. Stacker is made of stainless steel. It is used to place the pipe products after cutting.

What are the types of PVC pipe extrusion machine:

Benk Machinery, as customized PVC pipe production line suppliers, supplying mainly three types of PVC pipe extrusion equipment. They are as below.

three types of PVC pipe extrusion equipment:

1. single cavity pipe extrusion line for PVC pipe OD from 16mm to 800mm;
2. two-cavity pipe extrusion line for pipe OD from 16-63mm, 50-110mm and 90-160mm:
3. 4-strand PVC pipe extrusion line for pipe OD 16-32mm.

And Benk also supplies pipe coextrusion machine (with two or more extruders) for the multi-layer pipe.

Pls, refer to the specific parameters in the table below.

After knowing about the PVC pipe production line, you may have the worry that I have never operated such a big machine before. How do I manufacture PVC pipes?

If you have the same worry, read the following paragraphs, please.

How do you manufacture PVC pipes?

After buying the plastic pipe making machine, we supply specific raw material formulas, manual, video guide and even field guides on machine installation as well as workers’ training.

And any problem in the production process, we would solve it for you online or locally in no time. 

So don’t worry about how to manufacture PVC pipes. Before the purchase of the plastic pipe extrusion line,  let’s learn about the PVC pipe production process first.

How is PVC pipe extruded?

1.Mix raw material by mixing machine: PVC powder + additive→

2.load mixed material to feeder by screw loader →

3.Melt mixed material through a conical screw (designed for PVC powder especially) →

4.Extrude melted material into rough pipe shape by extrusion die →

4.cool and blow pipe to shape it better by water and vacuum in vacuum cooling machine →

5.haul off the pipe with the same speed of extrusion to control production speed and pipe thickness→

6.cut pipe into customized length(fixing length by limited switch or rotary encoder) by a cutter→

7.place and discharge pipe(controlled by a limited switch) by stacker automatically.

Still not very clear about the extrusion process. Pls refer to the PVC pipe production video below  (Also can refer to Benk’s PVC pipe production youtube link:https://youtu.be/xGt8-yfQa04)

The machine in the video is PVC two-cavity pipe extrusion production line. It can produce two pipes synchronously. Thus its output is double while its price is less than double. Besides, it runs stably than the 4-strand PVC pipe extrusion line. So it’s a better choice to invest in PVC two-cavity pipe extrusion production line as you step in the PVC pipe manufacturing field for the first time. After you get more experience in PVC pipe extrusion, you can try a 4-strand PVC pipe extrusion line. (But it’s just personal suggestion. And it is up to customers in the end surely. What we can do is to supply the best machine for you.)

Here are 3 main features of Benk’s PVC  pipe extrusion machinery for your reference:

1. Adopt the world’s famous brand electric parts, such as SIEMENS, SCHNEIDER, ABB, OMRON, etc.

2.Extruder screw and barrel material 38CrMoAl, nitriding process, bi-metallic

3.It can be controlled by PLC, more convenient.

After having a rough idea of PVC pipe extrusion equipment, believe you just can’t wait to learn about what to do step by step to establish a PVC pipe extrusion plant.

Now the last but surely not least part is coming!

What are the guidelines needed to set up the PVC pipe micro-scale manufacturing unit?

Before learning about the specific implementation steps, let’s see what the factors need consideration are first.

What are the factors that need consideration when establishing a PVC pipe small industry?

For the factors that need consideration, let’s see from two parts: customers and the Benk Machinery factory.

Customers:

For customers, there are 3aspects need consideration mainly:

sale: 

This is the enterprise’s survival. In simple terms, that is No Sale, No Profit.

So it’s vital to make sure you are to make good sales.

For the PVC pipe, the market is still promising because of its superior performance in use and its wide application. The product is in great demand still. But there have been many PVC pipe factories already, so you should choose a product you can compete with them.

You can choose the pipe type and diameter you want to produce according to its application. As we have introduced above, the PVC pipe can be used as a conduit pipe, water pipe, pressure pipe, drainage pipe, etc. For example, if you find it great use in agriculture, you can choose to produce the water pipe. Then you can tell the machinery factory later about the application, they would introduce pipe diameter according to your specific application. Or you can choose the diameter according to your research in the local market directly.

To conclude, you should research the market first to confirm the product you want to produce to make sure you can make good sales.

Solving sale problem, other things would become easy naturally.

capital:

It is another important factor you need consideration. You must be interested in what total capital is required to start a PVC pipe plant. Now let us tell you.

You should make sure you have at least 150,000$ as start-up capital so you can buy a small PVC pipe making machine and buy material to produce for one week first.  But the cost of the workshop fee is not included. The final cost depends on the actual situation. We, Benk Machinery, can help you to count the cost and profit according to customers’ specific requirements.

license:

After sale and capital are considered clearly. Before you start producing, you need to apply for some relative licenses. What kind of licenses and how long you can get them depends locally.

Benk Machinery factory:

Material formula:

After the purchase of the machine, we will supply material formula and material purchase suggestions.

PVC pipe machine:

About the machine, we can recommend a machine according to your budget and your requirements.

technical support:

Regarding technical support, we will supply operation instructions, video guides, and online support. And we can supply field installation, commissioning and worker training.

After sale, we supply thetesting machine free of charge, a 13months quality guarantee of spare parts and 24-hour technical support.

In conclusion, only the three aspects: sale, capital, license, PVC pipe manufacturers need to solve by themselves, we can assist to some extent. For material formula, machine, operation, cost&profit, etc, PVC pipe manufacturers can consult us directly for more information. We will help them to make the best project plan and give the support they need. So if you are going to have a pipe plant, welcome to contact us at any time.

Finally, let us see what to do step by step.

How can I start a small pipe manufacturing business?

1. Make sure you can make good sales of the product you are going to manufacture.
2. Contact PVC pipe extrusion machine manufacturers for machine information and cost & profit count.
3. Have a field visit to a machinery factory and buy the machine. (optional)
4. Register company, select factory site, going through relevant procedures.
5. Test machine before delivery and install it after arriving at your factory to produce pipes.
6. Sell PVC pipes.

The above steps are just for reference, pipe manufactures can adjust according to the actual situation.
