PVC trunking is a kind of trunks, which is mainly used for internal wiring routing of electrical equipment. Now, environmentally friendly & flame retardant PVC trunk is widely used. Jwell PVC Plastic Trunking Extrusion Line is an advanced manufacturing system designed to produce high-quality PVC trunking. PVC trunking, also known as cable trunking or conduit, is essential for organizing and protecting electrical wiring in residential, commercial, and industrial environments.

1. PVC trunking has the characteristics of insulation, arc protection, flame retardant and self extinguishing etc characteristics. 

2. PVC trunking mainly plays important role of mechanical protection and electrical protection. 

3. PVC trunking convenient for wiring, neat wiring routing, reliable installation, and also easy to find, repair and  replace wire routing line.

Main components:

1. Extruder:

Screw and Barrel: The heart of the extruder, where PVC material is melted and homogenized.

Motor: Powers the screw rotation, crucial for consistent extrusion.

2. T-Die Head:

Forming Die: Shapes the molten PVC into the desired trunking profile.

Calibrator: Ensures precise dimensions and smooth surface finish.

3. Vacuum Calibration Table:

Cools and solidifies the extruded PVC trunking while maintaining accurate dimensions.

4. Haul-Off Unit:

Pulls the formed trunking through the production line at a consistent speed to ensure uniform quality.

5. Cutting Machine:

Precisely cuts the trunking to the required lengths.

6. Stacking Unit:

Organizes the finished products for packaging and distribution.

Production Process

1. Material Feeding:

PVC resin, along with additives like stabilizers, lubricants, and colorants, is fed into the extruder.

2. Extrusion:

The material is heated, melted, and homogenized within the screw and barrel.

The molten PVC is then pushed through the forming die to create the trunking profile.

3. Calibration and Cooling:

The extruded profile passes through the vacuum calibration table, where it is cooled and solidified to maintain its shape and dimensions.

4. Hauling and Cutting:

The haul-off unit ensures smooth and continuous pulling of the trunking.

The cutting machine cuts the trunking into specified lengths with high precision.

5. Stacking and Packaging:

The finished trunking is neatly stacked and prepared for packaging and distribution.
