Polyethylene Foam Sheet Production Making Machine

Product Description

The Polyethylene Foam Sheet Production Making Machine is a state-of-the-art extrusion line designed for manufacturing high-quality polyethylene (PE) foam sheets, which are widely used in packaging, construction, and industrial applications. This machine combines extrusion, foaming, and calendaring processes to produce sheets with uniform density, excellent flexibility, and superior cushioning properties.

The production process begins with feeding PE resin, along with foaming agents and additives, into the extruder. The material is melted and mixed in the extruder, then forced through a flat die to form a continuous sheet. As the molten sheet exits the die, the foaming agent decomposes, creating a cellular structure within the material. The sheet is then cooled and shaped by a calendaring roller system, which controls the thickness and surface finish. Finally, the finished sheet is wound into rolls or cut into specific sizes.

The machine is capable of producing PE foam sheets in various thicknesses (0.5mm to 20mm), densities (10kg/m³ to 100kg/m³), and widths (up to 2000mm), making it suitable for a wide range of applications.

Features

High-Precision Thickness Control: The calendaring roller system, equipped with automatic gap adjustment, ensures a thickness tolerance of ±1%, meeting the strictest quality requirements.

Energy-Efficient Foaming System: The advanced chemical foaming technology reduces the amount of foaming agent required, while maintaining a uniform cell structure and low thermal conductivity.

Wide Material Compatibility: The machine can process various PE materials, including LDPE, LLDPE, and EVA (ethylene-vinyl acetate) copolymer, as well as recycled PE pellets with proper pretreatment.

High-Speed Extrusion: With a maximum extrusion speed of 15 meters per minute, the machine can achieve an output of up to 500 kg/h, ensuring high productivity for large-scale production.

Intelligent Monitoring System: The PLC-based control system with real-time data tracking allows operators to monitor and adjust process parameters remotely, improving production efficiency and reducing waste.

Application

Packaging Industry: PE foam sheets are widely used as protective liners, wraps, and inserts for packaging electronic products, glassware, furniture, and automotive parts, providing excellent shock absorption and scratch resistance.

Construction and Insulation: In building applications, they are used as thermal insulation materials for walls, roofs, and floors, as well as soundproofing layers in partitions and ceilings.

Automotive Interiors: The sheets are used for manufacturing door panels, headliners, and seat cushions, due to their lightweight, flexibility, and resistance to moisture and chemicals.

Sports and Leisure: They are also used in the production of yoga mats, camping pads, and protective gear, where comfort, durability, and impact resistance are essential.

Faq

Q: Can the machine produce anti-static PE foam sheets?

A: Yes, by adding anti-static additives to the raw material mixture, the machine can produce sheets with surface resistivity below 10^9 ohms, suitable for packaging sensitive electronic components.

Q: What is the minimum thickness of PE foam sheet the machine can produce?

A: The standard minimum thickness is 0.5mm, but thinner sheets (down to 0.3mm) can be produced with special calendaring rollers and process adjustments.

Q: How does the machine handle variations in raw material quality?

A: The intelligent control system can automatically adjust the temperature, pressure, and extrusion speed to compensate for minor variations in raw material melt flow index (MFI), ensuring consistent product quality.

Q: What is the recommended storage condition for the produced PE foam sheets?

A: Sheets should be stored in a dry, cool place away from direct sunlight and sources of heat to prevent aging and maintain their physical properties.
