In today’s world of modern electrical and data management, PVC cable trunking plays an essential role. It keeps wires organized, protected, and safe—whether in homes, offices, factories, or data centers. With the rapid growth of smart buildings and advanced electrical systems, the demand for custom PVC cable trunking has increased dramatically.
As a professional PVC cable trunking manufacturer with over 20 years of experience, SW has specialized in providing standard and custom PVC cable trunking for leading brands worldwide. We support OEM and ODM services, helping customers achieve the right size, material properties, and design features for their unique applications.
In this blog, we’ll take a deep dive into how PVC cable trunking is produced, how it can be customized, and why quality matters.
What is PVC Cable Trunking?
PVC cable trunking is a protective pathway system made from extruded polyvinyl chloride (PVC). It provides:
Electrical insulation for wires and cables
Protection against mechanical damage, dust, and moisture
Organization to keep wiring neat and accessible
Safety by reducing fire hazards and preventing short circuits
PVC is especially suitable because it is:
Lightweight and easy to extrude
Flame retardant and self-extinguishing
Non-conductive (excellent insulator)
Affordable and widely available
Customizable in shape, size, and color
This balance of properties makes PVC cable trunking the most common choice for electrical wiring systems worldwide.
The PVC Cable Trunking Manufacturing Process
Producing custom PVC cable trunking involves a plastic extrusion process, where raw PVC material is melted and shaped into the desired profile. Let’s walk through each step:
1 Raw Material Preparation
PVC resin is the primary ingredient.
Additives include:
Heat stabilizers – prevent degradation during extrusion
Flame retardants – enhance fire safety
Impact modifiers – improve toughness
UV stabilizers – prevent yellowing outdoors
Color pigments – provide white, gray, or custom colors
The materials are dry-blended and fed into the extrusion system.
2 Extrusion
Step 1: Feeding – The PVC mixture enters the hopper.
Step 2: Melting – A heated barrel with rotating screw melts and homogenizes the PVC.
Step 3: Shaping – The molten PVC is pushed through a precision extrusion die designed for the cable trunking profile (rectangular, square, slotted, etc.).
Step 4: Cooling – The extruded profile passes through a water bath to harden.
Step 5: Sizing – Calibration units ensure precise dimensions.
3 Cutting and Finishing
The continuous extruded trunking is cut into standard lengths (e.g., 2m or 3m).
Slots, holes, or perforations may be added depending on design.
Surface finishes such as smooth, matte, or textured are applied.
4 Customization
Logos, labels, or embossed branding can be added.
Colors can be matched to project requirements (e.g., white for offices, gray for industrial).
Flame-retardant and UV-resistant grades are available.
Customization Options for PVC Cable Trunking
Customization is a major advantage of working with a professional PVC cable trunking manufacturer like SW. Some of the key options include:
1 Dimensions and Shapes
Standard sizes: 10×10 mm to 100×100 mm and beyond
Rectangular, square, or slotted trunking designs
Compact or wide designs depending on cable load
2 Material Properties
Flame-retardant grades for high fire safety
UV-stabilized PVC for outdoor applications
Impact-modified PVC for industrial use
3 Color and Aesthetics
Standard colors: white, gray, black
Custom colors available for branding or design needs
Matte or glossy finishes
4 Branding and Labeling
Custom embossing with brand logos
Printed labels for easy identification
OEM/ODM designs for global partners
Quality Control in PVC Cable Trunking Production
High-quality PVC cable trunking requires strict quality assurance at every step:
Dimensional accuracy testing – ensures profiles meet design requirements
Impact resistance testing – evaluates durability
Flame retardancy testing – checks compliance with fire safety standards
UV exposure testing – for outdoor-grade trunking
Surface inspection – ensures a smooth, defect-free finish
At SW, we follow ISO-certified quality control systems, ensuring every batch of PVC cable trunking meets international standards.
Applications of PVC Cable Trunking
