PVC pipe extrusion line
According to different diameters of PVC pipes, Sharc Machine Company suggest you different models of PVC pipe extruders.
Also To produce different types PVC pipes: UPVC pipe, CPVC pipe, PVC-O pipe, PVC-M pipe and etc, SHARC will offer the turkey solution.
Suitable PVC pipe diameter: 16-63mm
In drainage systems, the commonly used pipe diameters are 40mm and 50mm;
In water supply systems, the commonly used pipe diameters are 25mm, 32mm and 40mm;
In wire and cable pipelines, the commonly used pipe diameters are 20mm, 25mm and 32mm.
This pvc pipe making machine has a 2 cavity design and can produce two pipes at the same time, greatly improving production efficiency and output.
Suitable PVC pipe diameter: 16-32mm
In water supply systems, the commonly used pipe diameters are 25mm, 32mm
In wire and cable pipelines, the commonly used pipe diameters are 16mm, 20mm, 25mm and 32mm.
This pvc pipe making machine has a 4 cavity design and can produce four pipes at the same time, greatly improving production efficiency and output.
Suitable multilayer PVC pipe diameter: 20-500mm
Multilayer PVC pipe, also known as co-extruded PVC pipe, is a pipe with a multilayer structure produced by co-extrusion technology. This pipe combines the characteristics of different materials to meet specific application requirements.
| Model | Pipe Diameter (mm) | Output (kg/h) | Main Motor (kW) |
|---|---|---|---|
| PVC32 (4-out) | 16–32 | 180–250 | 22 / 37 / 55 |
| PVC63 | 16–63 | 180–250 | 22 / 37 |
| PVC63 (2-out) | 16–63 | 250 | 37 |
| PVC110 | 20–110 | 250 | 37 |
| PVC160 | 50–160 | 250 | 37 |
| PVC250 | 75–250 | 450 | 55 |
| PVC450 | 110–450 | 450–800 | 55 / 110 |
| PVC630 | 250–630 | 800 | 110 |
| PVC800 | 315–800 | 1000 | 132 |
| PVC1000 | 400–1000 | 1200 | 160 |
What should we prepare before production of PVC pipes?
1.Building for factory
After clients choose the required PVC pipe production line, Engineers from SHARC will offer plant sizes for clients. Also Sharc can supply factory layout design service, it will show exactly about machines position, water, air and electricity information.
2.Materials
Main materials for PVC pipe extrusion is PVC resin and calcium carbonate and additives, according to different applications of PVC pipe, the formula will be different, if clients don’t know formulation of PVC pipe production, Sharc will send reference to them as reference.
Below is a reference formula of PVC pipe extrusion:
| NO | Materials Names | Quantity per batch (kg) |
| 1 | PVC resin | 100 |
| 2 | Calcium carbonate | 50 |
| 3 | Stabilizer | 3 |
| 4 | Stearic acid | 0.8 |
| 5 | CPE | 6 |
| 6 | Paraffin wax | 0.7 |
| 7 | ACR | 1 |
| 8 | Whitenner (for white color pipe) | 0.03 |
| 9 | Titanium dioxide (for white color pipe) | 1 |
3.Machines
PVC pipe production line will need several machines including mixer, extrusion line and etc.
Below is required machines list:
| NO | Machine Names | QTY |
| 1 | PVC mixer machine (hot and cooling mixer) | 1set |
| 2 | PVC pipe extrusion line | 1set |
| 3 | Extrusion die head for mold | 1set |
| 4 | Pipe belling machine (optional) | 1set |
| 5 | Co-extruder machine (optional, used for multilayer PVC pipes only) | 1set |
| 6 | Laser printer / inkjet printer | 1set |
| Auxiliary machines | ||
| 1 | Crusher machine | 1set |
| 2 | PVC pulverizer | 1set |
| 3 | Air Compressor | 1set |
| 4 | Chiller / Cooling tower | 1set |
4.Technician and labors
If clients need technician from SHARC for operation, we can do the support.
- Raw material preparation：
- Mixing
- Extrusion
- Vacuum Shaping and cooling
- Traction/Haul off
- Cutting
- Pipe Belling process
- Inspection
- Packaging
- Recycling
What should we pay attection during the production of PVC pipes?
- Try to use good raw materials in production. Good raw materials can ensure product quality and improve product brand influence.
- A good operator is very important. He can help customers make production run perfectly, reduce defective products, obtain perfect formulas, and reduce production of finished products. If customers need to get technicians from SHARC, they can contact SHARC and we will help them.
- To reduce the cost of production, now more and more clients are using co-extrusion for PVC pipe production, it is multilayer PVC pipes, the middle layer is cheap materials, outer layers are good materials for hardness and good looking. Eventually it helps to reduce the product manufacturing cost. This process will need two extruder machines or more.
- Screw speed, Barrel temperature, Mold temperature, Traction speed, Cooling temperature are important for getting high quality PVC pipes.
