Innovation and Efficiency: Extrusion of SPC

Innovation and Efficiency: Extrusion of SPC
17 de June de 2024 Sofía Sánchez

In Gestión de Compras we present solutions in plastic extrusion: SPC (Stone Plastic Composite) flooring and wall panels, a material that is positioning itself at the forefront of the construction sector due to its wide advantages and low production costs.

SPC floors, walls or wall panels are manufactured using a combination of mineral additives and PVC composite. The process consists of extruding a PVC profile through a three-, four- or five-roll laminator, which combines a PVC color film and a PVC profile (with a wear-resistant layer) by in-line lamination. The process is simple, and lamination is completed by heating without the need for adhesives.

The materials of SPC flooring or panels use environmentally friendly formulations, free of harmful substances such as heavy metals, phthalates, formaldehyde, etc., and comply with EN 14372, EN 649-2011, IEC 62321, GB 4085-83, etc. standards. The density of SPC boards manufactured is 1.9-2 tons/cubic meter, and the shrinkage rate of SPC board is ≤ 1 ‰ (shrinkage test standard: 80℃, standard for 6 hours).

Advantages of SPC flooring and wallboard.

The manufacturing and processing process of SPC wall panels is simpler compared with wood flooring. Its installation method is usually connected with seamless grooved connections, with high construction efficiency, high quality, aesthetic, easy cleaning (washable), long weather resistance, no fading, eco-friendly, non-toxic and odorless.

At Gestión de Compras, we specialize in the production and supply of industrial machinery for the manufacture and supply of these high quality materials, ensuring that our customers can develop products that meet the highest industry standards.

The production of SPC flooring equipment includes:

  1. Raw material mixer (granulation method can also be selected).
  2. Extruder
  3. UV (painting) equipment.
  4. Splitting equipment.
  5. Grooving equipment.
  6. Packaging equipment (optional as required).

Production of SPC wall panel equipment:

  1. Mixing equipment (granulation method can also be selected).
  2. Extrusion equipment.

spc extruder

We mainly supply parallel and conical twin screw extruders, adapting to the specific needs of each project. Currently, most of the extrusion equipment used are conical twin screw extruders, and parallel twin screw extruders are rarely used due to their high prices.

However, based on the effectiveness of equipment use and after-sales service feedback, we recommend choosing a parallel twin screw extruder + auxiliary machine GDC1350, as the operation of the parallel twin screw extruder is simpler compared with the conical extruder, and the professional requirements for operation are simplified, especially for the installation and adjustment of the screw barrel. The parallel twin screw extruder is very simple, and the adjustment difficulty of the conical twin screw extruder is high.

At present, there are three major problems related to manufacturing costs when manufacturing SPC sheet in Europe: first, professional technical problems; the second problem is the production labor cost and electricity cost; the third problem is the cost of raw materials.

  1. Professional technical problems. Our company can carry out turnkey projects and assign dedicated operators to operate and train in the factory within the first year of equipment delivery and operation.
  2. The problem of labor and electricity cost. It is recommended to choose extrusion equipment with high extrusion capacity, such as GDC175 parallel twin screw extruder with a production capacity of 60-80 tons/day; over our GDC130 parallel twin screw extruder or GDC110/220 conical twin screw extruder with a production capacity of only 25-30 tons/day.
  3. The problem of raw material cost. The main reason is the cost of calcium carbonate. In Asia, the price of calcium carbonate does not exceed 28 Eur/Ton, while in Europe, the price is above 90 Eur/Ton.

In Gestión de Compras, we have the capacity to import from other countries, reducing costs while maintaining the quality of the product. In our firm we are committed to provide customized solutions and high quality equipment to meet your specific needs, providing the most favorable price and the most perfect configuration.
