The advantages of the three-layer co extrusion blown film machine are high production efficiency, simple operation, cost savings, and good film quality. Therefore, it has been widely used in the packaging industry and other fields. With the advancement of technology and market demand, the performance and technology of three-layer co extrusion blown film machines are constantly improving, providing more possibilities for producing high-quality films.
The co extrusion die is one of the core components of a three-layer co extrusion blown film machine. Its function is to uniformly merge three layers of melt from different extruders together and extrude the melt through the annular gap to form a tubular film. The internal structure design of the mold head is crucial to ensure that the three-layer melt does not mix unevenly during the merging process.
What are the common problems encountered in the use of three-layer co extrusion blown film machine
Unstable pressure: In the production process, unstable pressure of three-layer co extrusion blown film machine is a common problem. This may be caused by uneven feeding volume, wear of internal machine components leading to air leakage, and other reasons. To solve this problem, it is necessary to promptly check the operation of each component to ensure the normal operation of the machine.
Inaccurate temperature control: During the use of the three-layer co extrusion blown film machine, inaccurate temperature control is also a common problem. This may lead to unstable quality of the produced film and even quality issues. To solve this problem, it is necessary to regularly check the operation of the temperature control device to ensure that the temperature is within the set range.
Material mixing: During the production process, the three-layer co extrusion blown film machine may experience material mixing. This may be caused by damage to the screws inside the machine or a malfunction in the feeding system. Solving this problem requires timely replacement of damaged components and maintenance of the machine.
Poor film quality: During production, the three-layer co extrusion blown film machine may experience poor film quality. This may be caused by unstable extrusion pressure of the machine, inappropriate processing temperature, or unreasonable die design. To solve this problem, it is necessary to adjust the machine parameters to ensure that the quality of the produced film meets the standards.
Insufficient lubrication: Insufficient lubrication is also a common problem during the use of three-layer co extrusion blown film machines. This may lead to increased wear and tear on machine components, thereby affecting the normal operation of the machine. To solve this problem, it is necessary to regularly lubricate and maintain the machine to ensure its smooth operation.
The three-layer co extrusion blown film machine is an equipment used for producing thin films. Its working principle is to heat different types of raw materials together to a molten state, and then extrude them through an extrusion head to form a thin film. The three-layer co extrusion blown film machine has relatively high work efficiency and stability, and can be widely used in fields such as food packaging, medical equipment packaging, and agricultural film covering.
The screw speed determines the extrusion speed of plastic. In the three-layer co extrusion process, it is necessary to adjust the screw speed of different extruders according to the thickness requirements of each layer of film and the characteristics of the raw materials. For example, if you want to increase the thickness of a certain layer of film, you can appropriately increase the screw speed of the corresponding extruder. At the same time, the adjustment of screw speed should also consider the load of the extruder and the plasticizing effect of the plastic.
