What is PVC Profile Extruder Machine?

Our single screw PVC profile extruder machine is engineered to meet the highest standards of quality and efficiency, leveraging advanced cold extrusion technology.

This method ensures precise, high-quality profiles suitable for various industries, including construction and decoration.

Our PVC profile extruder exclusively uses granulated PVC materials, making it ideal for manufacturers focused on environmental sustainability.

These profiles offer exceptional durability, weather resistance, and aesthetic appeal, making them ideal for both residential and commercial use.

Key Components of Our PVC Profile Extruder Machine Line

General (thermal) extrusion process

PLC type single screw extruder

Main Extruder

The single screw extruder is the core of the PVC profile extruder machine line. It melts and mixes the PVC resin with additives to form a uniform melt. This type of extruder is cost-effective and suitable for producing simple profiles and basic applications.

The extrusion die shapes the molten PVC into the desired profile. It determines the profile’s dimensions and surface finish. Precise die design is crucial for producing accurate profiles with minimal defects.

Vacuum-Tank

Vacuum Sizing Tank

After shaping, the profile needs to be cooled to retain its shape and dimensions. The cooling system often includes water tanks where the profile is immersed to cool rapidly.

Haul-Off Machine and Cutting Machine

This machine pulls the profile through the extrusion line at a controlled speed, ensuring that the profile maintains its dimensions and consistency. The speed of the haul-off machine must be synchronized with the extrusion speed to prevent stretching or compression of the profile.

Cut the continuous profile into specific lengths and stack them for further handling. Precision cutting ensures clean edges and accurate dimensions, which are vital for the final application of the profiles. 

Comparison of Cold Extrusion and Hot Extrusion Processes for PVC Profiles

Hot Extrusion (Vacuum Forming Extrusion)

  • Process Characteristics:
    • Surface Quality: Typically results in a matte finish with potential surface defects like pull lines and shrink marks.
    • Material Use: Suitable for PVC products with filler content below 30%.
    • Production Efficiency: High production speed and efficiency, making it ideal for high-strength and tough profiles.
    • Dimensional Precision: Profiles may have larger tolerances compared to cold extrusion.

Cold Extrusion (Cold Top/Hard Top Forming)

  • Process Characteristics:
    • Surface Quality: Achieves a mirror-like, high-gloss surface.
    • Material Use: Capable of using high filler content materials, such as high calcium components, which reduce raw material costs.
    • Production Efficiency: Lower production speed and efficiency compared to hot extrusion. Suitable for profiles requiring high surface quality.
    • Dimensional Precision: Produces profiles with very tight tolerances and high precision.

Advantages & Disadvantages of Hot Extrusion (Vacuum Forming Extrusion)

  • Advantages:
    • High Efficiency: Fast production speeds, ideal for high-volume manufacturing.
    • Good Strength and Toughness: Produces profiles with strong structural integrity.
    • Cost-Effective for Low Filler Content: Best suited for profiles with filler content below 30%.
  • Disadvantages:
    • Higher Mold Costs: More expensive due to the need for complex molds.
    • Surface Quality: Matte finish with potential for surface defects, such as pull lines and shrink marks.
    • Larger Tolerances: Dimensional precision may not be as high as cold extrusion.
    • High Equipment Requirements: Requires high-quality extruder configuration and PVC formulation.

Advantages & Disadvantages of Cold Extrusion (Cold Top/Hard Top Forming)

  • Advantages:
    • High Surface Quality: Produces profiles with a glossy, mirror-like finish.
    • Dimensional Precision: Achieves tight tolerances, making profiles fit precisely with CAD designs.
    • Lower Raw Material Costs: Can use high filler content, reducing overall material costs.
  • Disadvantages:
    • Lower Production Efficiency: Slower production speeds compared to hot extrusion.
    • Reduced Strength and Toughness: Profiles may be less tough and strong due to high filler content.
    • Handling and Surface Protection: Requires protective measures such as coatings or PE bags to prevent surface damage during handling and transportation.

PVC Profile Extruder Machine Related Q&A

May help you know more

What is the first thing you need to confirm?

The first thing you need to confirm is that you are using granulated PVC material. Our single screw extrusion machines are specifically designed to work with PVC granules, not powder.

  • Hot Extrusion: Suitable for general PVC profiles where high production efficiency and strength are prioritized over surface finish.
  • Cold Extrusion: Ideal for high-quality applications requiring a superior surface finish and precise dimensional accuracy, such as window frames, stair handrails, cable ducts, and skirting boards.
