In the world of modern interior decoration and construction, PS (Polystyrene) skirting is becoming an increasingly popular material thanks to its lightweight, durable, and aesthetically pleasing properties. Behind the scenes of these well-finished products lies an advanced and precisely engineered system: the PS Skirting Production Line. In this blog post, we will explore the key components and processes that drive the production of high-quality PS skirting boards—particularly through the innovative machinery provided by Feininger.

Why Choose Feininger's PS Skirting Line?

Unlike traditional chemical foaming systems, Feininger PS skirting line production machines utilize supercritical CO₂ physical foaming, significantly reducing the environmental footprint of production. This technique not only lowers the product density but also avoids the use of harmful chemical blowing agents—making the final products safer, more eco-friendly, and in line with global sustainability standards.

Breakdown of the PS Skirting Line Production Process

Let's take a step-by-step look at how Feininger's PS skirting production line works, from raw material input to final packaging.

1. Material Mixing

The process starts by adding raw materials in specific proportions into a high-speed mixer. These materials are thoroughly blended and homogenized to create a consistent base for extrusion.

2. Feeding and Metering

The mixed material is transferred to a feeder bin, where it is measured and delivered to the main extruder via a quantitative feeder. This ensures that the exact amount of material required is consistently supplied.

3. Extrusion and Heating

Inside the main extruder, a high-temperature screw conveys the raw materials to a heat exchanger. This component ensures uniform thermal distribution, which is critical for optimal foaming and material properties.

4. Supercritical CO₂ Injection

One of the defining technologies of Feininger’s system is the precise injection of supercritical CO₂ foaming agent. This step takes place just before the material exits the die. It’s a clean, physical foaming process that reduces material density and enhances environmental safety.

5. Moulding and Shaping

Once extruded, the foamed material is pushed through a mould and a two-stage shaping jacket. This cools and forms the high-temperature product into its desired skirting board profile.

6. Water Cooling

After initial shaping, the material passes through a water cooling channel, further stabilizing the structure and ensuring dimensional accuracy.

7. Haul-Off and Cutting

The cooled PS skirting boards are then pulled forward by a tractor (haul-off unit) and precisely cut to length using a fixed-length cutting system.

8. Final Product Packaging

The finished skirting boards are inspected, bundled, and packaged for distribution—ready to serve as premium decorative solutions for homes and commercial buildings alike.
