PVC Conduit Pipe Making Machine

Main Technical Parameters

Note: Actual production output can vary according to pipe diameter, wall thickness, PVC formulation, tooling and operating conditions.

Produce Multiple PVC Conduit Sizes on One Machine

One of the important requirements for conduit manufacturers is the ability to serve different customer specifications.

ANDA offers two main production ranges:

PVC-32 Double Output

Designed for conduit outside diameters from approximately 16 to 32 mm.

It uses a 55/110 conical twin-screw extruder and offers nominal production capacity of approximately 125 kg/h.

This configuration is particularly suitable for manufacturers primarily producing common smaller electrical conduit sizes.

PVC-63 Double Output

Designed for a wider conduit range from approximately 16 to 63 mm.

It uses a 65/132 conical twin-screw extruder and offers nominal production capacity of approximately 200 kg/h.

This model is suitable for manufacturers requiring a broader diameter range or higher production capacity.

Different Diameters and Wall Thicknesses

Manufacturers do not necessarily need a separate extrusion machine for every conduit specification.

By changing suitable tooling components and adjusting production parameters, different pipe diameters or wall thicknesses can be manufactured on the same applicable machine configuration.

This flexibility is useful for factories serving multiple customers or markets where electrical conduit specifications vary.

Consistent Finished PVC Conduit Quality

Machine performance should ultimately be evaluated by the conduit it produces.

The combination of controlled extrusion, pipe forming, vacuum calibration, cooling and synchronized hauling is designed to support consistent finished-pipe production.

Uniform Pipe Diameter

Vacuum calibration helps control conduit outside dimensions during continuous extrusion.

Consistent Wall Thickness

Stable material flow and synchronized haul-off conditions help maintain consistent pipe wall dimensions.

Good Roundness

Vacuum sizing and controlled cooling help the conduit maintain its required shape.

Smooth Inner and Outer Surface

Suitable PVC plasticization and stable extrusion conditions contribute to a smooth finished pipe surface.

Stable Cutting Length

Coordinated hauling and cutting allow the finished conduit to be produced according to the required length.

PVC Conduit Pipe Making Machine Components

A complete conduit manufacturing system consists of multiple processing sections working continuously.

1. Conical Twin-Screw Extruder

The conical twin-screw extruder is designed for processing PVC compounds and provides the plasticization required for stable conduit extrusion.

ANDA offers 55/110 and 65/132 extruder configurations according to the required production range.

The appropriate extruder should be selected based on conduit diameter, wall thickness and required output rather than maximum capacity alone.

2. Double-Output Conduit Mould

The double-output extrusion tooling allows two PVC conduit pipes to be formed simultaneously.

Suitable tooling can be selected according to the required pipe diameter and wall thickness.

By changing the corresponding mandrel or mould lip and adjusting production parameters, manufacturers can produce different conduit specifications within the machine's applicable range.

3. Vacuum Calibration Tank

After leaving the extrusion mould, the conduit enters the vacuum calibration section.

Controlled vacuum sizing helps maintain the required pipe outside diameter and roundness while cooling begins to stabilize the newly formed conduit.

4. Cooling Section

The cooling system removes heat from the extruded conduit and stabilizes its dimensions before hauling and cutting.

Proper cooling is important for maintaining pipe shape during continuous high-volume manufacturing.

5. Haul-Off Machine

The haul-off machine continuously pulls the two conduit pipes through the production process.

Its speed is coordinated with the extruder to maintain stable production conditions.

Adjustable speed also allows the production process to be optimized for different pipe diameters and wall thicknesses.

6. Cutting Machine

The cutting unit automatically cuts the conduit into the required finished length as it moves through the line.

Coordinated hauling and cutting support continuous production while reducing unnecessary interruptions.

7. Pipe Stacker

After cutting, finished conduit pipes are collected and organized by the stacker for easier downstream handling.

FAQ

What does a PVC conduit pipe making machine do?

It processes PVC compound through extrusion and forms it into electrical conduit pipe. The production process typically includes extrusion, forming, vacuum calibration, cooling, hauling and cutting.

What pipe sizes can this machine produce?

ANDA currently offers configurations covering approximately 16–32 mm and 16–63 mm outside diameters, depending on the selected machine.

What is the output of the PVC conduit machine?

The PVC-32 double-output model has a nominal capacity of approximately 125 kg/h, while the PVC-63 double-output model reaches approximately 200 kg/h. Actual output varies according to pipe specifications and processing conditions.

Why use a double-output PVC conduit machine?

Double output allows two conduit pipes to be manufactured simultaneously, which is particularly useful for high-volume production of small- and medium-diameter electrical conduit.

Can the same machine produce different pipe diameters?

Yes. Within the applicable machine range, different conduit diameters can be manufactured by using suitable mould components and adjusting the corresponding production parameters.

Can the machine produce different wall thicknesses?

Different wall thicknesses can be produced within the machine's applicable processing range by selecting suitable tooling and adjusting extrusion and haul-off conditions.

What is the difference between PVC-32 and PVC-63?

PVC-32 covers approximately 16–32 mm conduit and uses a 55/110 extruder with nominal output around 125 kg/h. PVC-63 covers approximately 16–63 mm and uses a 65/132 extruder with nominal output around 200 kg/h.

How do I choose the correct machine?

Start with your required conduit diameter, wall thickness and production capacity. These three specifications are the most important information for determining the appropriate extruder and tooling configuration.
