Key Components of PVC Profile Extruder Machine Line

General (thermal) extrusion process

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 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 bags to prevent surface damage during handling and transportation

LED Lighting PC Profiles Extrusion Line

Our PC/PMMA profile extrusion lines are designed to process high-quality Polycarbonate (PC) and Polymethyl Methacrylate (PMMA) materials, creating superior LED lighting profiles such as diffusers and tubes. These profiles come in various finishes and are essential for modern LED lighting solutions.

They come in various configurations and sizes, such as flat, tubular, semi-circular, and irregular. Some have beam angles, often called optical lenses, and some do not. The colors are transparent, translucent, and milky white. Depending on the application, some are rigid, and some are flexible.

Including glossy, two-color co-extruded, frosted, sandblasted, wide diffusion, semi-circular, and so on.

• LED lighting covers or lampshade

• Outdoor and architectural lighting solutions

• Decorative lighting profiles

Extruded hosts are our most mature products. The unique screw and barrel for the PC material of the extruder are made of high-strength nitrided alloy steel (38CrMoALA) or high-strength quenched alloy steel (9Cr18MoV). We have especially designed the Gravimetric Dosing Controller system for rigid profiles

Co-extrusion is a process required for the production of two-color lamps, lampshades, etc. Our co-extrusion equipment can be controlled by PLC system together with the host machine and haul-off to achieve precise extrusion production results

The subsequent production steps are hauling and cutting. We can laminate the surface of the product after the production of PC lamps and lanterns according to the customer’s demand, in order to protect the PC lamps and lanterns from wear and tear.
