2. Manufacturing Process

▶

The manufacturing process for flooring raceways, trunking, or ducts involves several steps to ensure that the products are durable, functional, and compliant with industry standards. These products are typically used for organizing and protecting cables, wires, and other electrical components in both residential and commercial spaces. Here's an overview of the general manufacturing process for these products:

1. Material Selection

Raw Materials: The primary materials used for making raceways, trunking, and ducts are typically PVC (Polyvinyl Chloride), ABS (Acrylonitrile Butadiene Styrene), metal (aluminium or steel), and sometimes high-density polyethylene (HDPE). The material is chosen based on factors like durability, flexibility, environmental resistance, and intended use.

2. Compounding and Polymerization (for Plastics)

If the product is made of plastic, the raw polymer materials undergo a compounding process where various additives (such as stabilizers, plasticizers, and flame retardants) are mixed with the base plastic to achieve the desired properties.

3. Extrusion Process (for Plastic Ducts/Raceways)

Extruder Setup: The compounding material is fed into an extruder machine, where it is heated and forced through a die to create continuous profiles of the desired shape (rectangular, square, or custom designs).

Cooling: The extruded material is cooled using water or air to solidify it into a rigid form.

4. Molding (for Special Shapes and Plastic Components)

For some raceways or trunking designs, injection Molding might be used to create more complex shapes or sections with detailed features (like snap-on covers or connectors).

Injection Molding: The compound is injected into a Mold under high pressure, forming specific components that may include internal partitions or cable channels.

5. Metal Duct Production (if applicable)

Rolling: For metal ducts (usually made from aluminium or galvanized steel), the process starts by rolling sheets of metal to the required thickness.

Cutting and Bending: The sheets are then cut into strips or panels, which are bent into the desired shape (rectangular or oval ducts). This process often involves a combination of cutting, punching, and folding using specialized machinery.

6. Surface Treatment (Optional)

Galvanizing (for metal ducts): Metal ducts are often galvanized or coated with a layer of zinc to prevent corrosion.

Coating (for plastics): Some plastic ducts may be coated or treated with UV stabilizers to enhance their weather resistance and longevity when exposed to outdoor elements.

3. Challenges and Limitations of Flooring Trunking / Ducts Manufacturing

▶

Flooring raceways, trunking, and ducts are essential components in the construction of electrical systems and infrastructure, especially in commercial and industrial settings. They provide a safe, organized, and protected route for cables, wiring, and other utilities while maintaining a clean and efficient workspace. However, the manufacturing of these products involves a number of challenges and limitations that manufacturers must address to ensure functionality, safety, and cost-effectiveness. Below are some key challenges and limitations associated with the manufacturing of flooring raceways, trunking, and ducts:

1. Material Selection and Quality Control

Corrosion Resistance: Since raceways, trunking, and ducts are often used in environments where exposure to moisture, chemicals, or harsh conditions is common, the material choice is critical. Metals like aluminum, steel (galvanized or coated), and plastic are often used, but maintaining consistent corrosion resistance, especially for steel-based products, can be challenging. Inadequate coating or poor material quality may result in premature deterioration and failure.

Fire Resistance: Many of these systems must meet fire resistance standards, which can involve using materials that are difficult to work with, such as fire-resistant plastics or treated metals. Achieving the necessary fire-retardant properties without compromising strength or ease of installation is a challenge.

2. Precision and Manufacturing Tolerances

Dimensional Accuracy: The components must adhere to tight tolerances, as even small variations can affect how well the raceway, trunking, or duct aligns with other system components or fits within installation spaces. Small dimensional variations can lead to poor fitment, which may result in costly rework or installation delays.

Consistency in Profile and Shape: For raceways and ducts, maintaining uniform profiles and shapes throughout the production process is essential. Any deviations from the designed profiles, especially for modular trunking systems, could lead to difficulties during assembly or installation.

3. Complexity of Designs and Customization

Modular and Custom Designs: Many raceway and trunking systems are designed to be modular, allowing for flexibility in installation. Custom designs often require modifications to standard molds or dies, which can increase manufacturing complexity. Tailoring designs to suit different building layouts, cable management needs, or special project requirements can lead to longer production times and higher costs.

Integration with Other Systems: In some cases, raceways need to accommodate additional features such as ventilation, cable dividers, or power distribution modules. Designing these products to integrate seamlessly with other electrical and mechanical systems while maintaining performance standards is challenging.

4. Manufacturing Processes and Tooling

Tooling Wear: Manufacturing processes for raceways, trunking, and ducts often involve punching, cutting, extruding, or bending metal and plastic. Over time, tooling can wear out, leading to inconsistencies in the finished products (e.g., holes that are misaligned or deformed edges). Tooling maintenance and replacement are costly and can lead to production downtime.

Extrusion and Molding Challenges: Extruding or molding plastic-based raceways and ducts to precise specifications is a complex process. Achieving a consistent wall thickness, surface finish, and proper dimensional accuracy across large production runs can be difficult, especially when producing long sections of raceway or ducting.

5. Surface Finish and Aesthetic Quality

Surface Defects: Raceways and trunking are often visible in the final installation, especially in commercial or office environments. Scratches, dents, or imperfections in the finish can detract from the appearance. Ensuring a consistent, smooth surface without defects during the manufacturing process is difficult, especially when using materials like metal that are prone to scratching or when molding plastic.

Coating and Color Consistency: When raceways are coated (e.g., powder coating for metals or UV-resistant coatings for plastics), achieving a uniform thickness and color consistency is challenging, particularly when dealing with complex profiles or intricate designs. Inconsistent coatings can lead to areas of weakness or reduce the aesthetic appeal of the product.
