Overview of Our Sheet Extrusion Lines

 
 
 
 
LITAI PP PS Sheet Extruder

With over 24 years of experience in China, LITAI specializes in manufacturing high-performance sheet extruder lines for a wide range of thermoplastic materials, including PP, PS, PET, PLA, and more. Our extrusion systems deliver high output capacity, precise thickness control, and long-term operational stability. Widely used in packaging and industrial component production, our extrusion lines are engineered to meet the changing demands of global manufacturers with maximum efficiency, precision, and adaptability:

High-Speed Production: An optimized structural design enables significantly higher output without compromising product quality.

Energy Efficiency: Advanced control systems reduce energy consumption and minimize overall operating costs.

Safety & Compliance: Integrated safety mechanisms ensure full compliance with international standards, including CE and ISO-certified systems.

Flexible Adaptability: Modular design allows for easy configuration across different sheet thicknesses, widths, and material types.

Sheet Extrusion Lines

 
 
 
 

We offer fully automatic sheet extrusion lines for thermoplastics such as PP, PS, PET, and PLA, with single-layer and dual-layer models available to suit different production requirements. In addition to standard lines, we also provide customized sheet extruders or sheet extrusion lines based on your specific production needs.

Understanding the Key Parts of a Sheet Extrusion Line

 
 
 
 

Key components of a sheet extrusion line work together to transform raw thermoplastic materials into high-quality sheets. Here's how they contribute to efficient production.

Sheet Heating Device: The independently controlled ceramic heating plate offers up to 96% efficiency, reducing energy consumption by around 30% compared to traditional heating methods. Made with high-temperature resistant materials like alumina, it ensures excellent safety and durability. With a lifespan of over 100,000 hours and no moving parts, it significantly lowers maintenance costs.
Automatic Screen Changer: The screen changer is controlled by a hydraulic system, allowing non-stop filter changes and ensuring a continuous, stable production process.
45° Oblique Extrusion Die Head: Accurate temperature control and adjustable die lip design ensure optimal processing of heat-sensitive materials and uniform sheet thickness.
Three-Roller Calender: Presses the extruded melt into a flat sheet and cools it simultaneously. Features an oblique three-roller design for a simple structure, easy operation, and convenient maintenance.

Customer Success Stories

 
 
 
 
PP/PS Double-Layer Sheet Extruder

From Low-Margin to 30% Profit: UAE Cup Maker's Two-Color Upgrade

A customer from the UAE initially produced transparent PP disposable cups, but this type of cup had a low price, resulting in low profit margins. After conducting a market assessment, he discovered that two-color cups were priced significantly higher and offered better market opportunities. He then purchased our TJS-750F machine, which helped him increase his profit margin by 30%.

Automatic PP/PS Single-Layer Sheet Extrusion Machine Machine

Food Packaging Solution: P&B Food Tray Thermoforming and Sheet Extrusion Production Lines

This customer has a new project in food packaging production. They are seeking a high-quality and highly experienced machine supplier who can provide a complete production line—from sheet extrusion machines to thermoforming machines—for food packaging products. Currently, the equipment is already in production and use at the customer's factory.

Fully-Automatic PP/PS Sheet Extrusion Machine Machine

Hullaf Turkey: Food Tray Thermoforming & PP/PS Sheet Extrusion Machine Lines

This is a new project for food packaging production for this customer. The client visited multiple suppliers in China, primarily seeking a high-quality, service-oriented, and experienced machine supplier who could provide a two-month training program on equipment operation for their technical engineers. From the project initiation, the client visited our factory, conducted three interviews, and held several meetings to finalize the equipment plan and place the order. The entire process took about four months. Currently, the equipment is already in production and operation at the client's factory.

PET/PLA Single-Layer Sheet Extrusion Line

Fruit Packaging Company: TTF-820AF & TJP-900E Solution

The customer requires precise control over product thickness. To meet this, we designed a solution incorporating the TTF-820AF and TJP-900E machines, equipped with a thickness gauge to ensure all sheets produced by the TJP-900E comply with the thickness specifications. Based on the sheet consumption calculated for the TTF-820AF, the TJP-900E can produce 400 kg of sheet per hour, guaranteeing that sheet output exceeds the consumption rate.

FAQ
  • Q: What materials can be processed by a sheet extrusion line?

    A: Our sheet extrusion lines can handle a wide range of thermoplastics, including PP, PS, PET, PLA, and others. Custom material options are also available based on your specific requirements.
