The multi-layer co extrusion casting film extrusion production line consists of multiple parts, each with specific functions. The following will introduce these parts and their functions one by one, and explore the scope of use of multi-layer co extrusion casting film extrusion production lines.
The multi-layer co extrusion casting film extrusion production line mainly consists of the following parts:
Melt supply system: The melt supply system is the starting point of the entire production line, responsible for heating the raw materials and converting them into an extruded molten state. This system typically includes a hopper, melting furnace, and heating system. The hopper is used to store raw materials, the melting furnace heats the raw materials to a molten state, and the heating system provides the required heat energy.
Extruder: The extruder is the core part of the multi-layer co extrusion casting film extrusion production line. It is responsible for extruding molten raw materials into thin films. An extruder usually consists of a feeding system, a screw, and a die head. The feeding system transports the molten raw material to the extruder, and the screw pushes the raw material into the die head, which determines the shape and size of the extruded film.
Multi layer co extrusion head: The multi layer co extrusion head is a key part of the multi layer co extrusion casting film extrusion production line. It is responsible for extruding different molten raw materials into multi-layer co extruded flow films. The multi-layer co extrusion head is usually composed of multiple extrusion outlets, each responsible for extruding a layer of raw material. By adjusting the position and size of the extrusion outlet, the thickness and distribution of different layers can be controlled.
Cooling system: The cooling system is used to quickly cool the extruded film, allowing it to solidify and maintain the desired shape and size. The cooling system usually includes cooling rollers and cooling fans. The cooling roller cools the hot film by conducting heat, while the cooling fan accelerates the cooling process by air cooling the film.
Tension control system: The tension control system is used to control the tension of the extruded film on the production line, ensuring the smooth operation and stable quality of the film. The tension control system usually consists of a tension sensor, tension control device, and tension adjustment device. The tension sensor is used to measure the tension of the film, and the tension control device adjusts the tension adjustment device based on the sensor signal to achieve automatic control of tension.
The multi-layer co extrusion casting film extrusion production line has a wide range of applications. It can produce films of various materials, such as polyethylene, polypropylene, polyvinyl chloride, etc. These films can be used in fields such as packaging materials, agricultural covering films, building films, and protective films for electronic products. Multilayer co extruded cast films have excellent physical and mechanical properties, such as transparency, strength, heat resistance, etc., which can meet the needs of different industries.
In summary, the multi-layer co extrusion casting film extrusion production line consists of a melt supply system, an extruder, a multi-layer co extrusion flow head, a cooling system, and a tension control system. Each part has a specific function to jointly complete the production process of multi-layer co extruded film.
