OLLITAL Plastic Sheet Extrusion Line Extruder

            Plastic sheet production line wire extruder is a kind of equipment specially used to process plastic raw materials into various plastic sheets, which is widely used in packaging, construction, electronics and other fields. Through efficient extrusion and cooling technology, the equipment can produce plastic sheets with different thicknesses, widths and performances to meet the market demand for diversified products.

Design and functional features

• Efficient extrusion: The wire extruder adopts a high-performance screw design to ensure that the plastic raw materials can be melted quickly and evenly, improving production efficiency.

• Diversified production: The equipment can produce various types of plastic sheets, such as transparent sheets, colored sheets and composite materials, according to different needs.

• Accurate temperature control: Equipped with an advanced temperature control system, it can accurately adjust the temperature at each stage to ensure the uniformity and molding quality of the material.

• Stability and safety: The stability and safety of the equipment are taken into consideration in the design, and multiple protection measures are set to ensure safe and reliable operation.

Working principle

• Feeding stage: The plastic raw materials are fed into the extruder through the feed port in the form of granules or powder.

• Melting and mixing stage: Under the action of heating, the screw heats the raw materials to a molten state and mixes them evenly.

• Extrusion molding stage: The molten plastic is extruded through the die to form a plastic sheet of the required thickness and width.

• Cooling stage: The extruded sheet passes through the cooling device to quickly cool and shape it to ensure product quality.

Equipment components

• Feeding system: Responsible for feeding plastic particles into the extruder, usually composed of a conveying device and a feeding device.

• Extrusion system: Including screws and barrels, responsible for melting and extruding raw materials.

• Mold system: Designed to extrude molten plastic into sheets of a specific shape, the design of the mold directly affects the quality of the finished product.

• Cooling system: The extruded sheet is cooled through a cooling water tank or air cooling system to ensure its stability.

• Cutting system: Cut the cooled sheet into the required specifications for subsequent processing and packaging.

Application areas

• Packaging industry: Used to produce various packaging materials, such as food packaging, industrial packaging, etc., to provide excellent protection performance.

• Construction industry: Produce plastic sheets for construction, such as transparent covers, partitions, etc., with good weather resistance and aesthetics.

• Electronics industry: manufacturing protective covers and insulation materials for electronic components to ensure product safety and reliability.

• Medical industry: used to produce protective covers and packaging materials for medical devices to ensure sterility and safety

Recycling of crushed waste plastics The crushed waste is put into the hopper, melted in the heating zone of the screw, and then rotated to extrude the material.

Water cooling and shaping The molten plastic is extruded through a die and then passed through a water channel to be cooled and shaped.
