What is the scope of application of plastic film screen changer?
The application scope of plastic film screen changers is quite extensive. Below are its main application fields and specific descriptions:
Polymer Molding Production Lines
Plastic film screen changers can be widely used in various polymer (including plastics and rubbers) molding production lines, such as blown film, cast film, sheet, pipe, and profile production lines. These production lines require filtering out impurities in the melt during the production process to ensure the quality of plastic products.
Plastic Recycling and Granulation
Screen changers also play an important role in plastic recycling and granulation processes. They can filter out impurities and contaminants in recycled plastics, enabling their reuse. Meanwhile, during the granulation process, screen changers ensure the purity of the melt, improving granulation efficiency.
Extrusion Laminating Production Lines
Extrusion laminating production lines are typically used to produce multilayer composite materials, such as multilayer coextruded films and composite boards. On these production lines, screen changers ensure the purity and uniformity of each layer of melt, thereby improving the overall quality of the composite materials.
Other Applications
Besides the above-mentioned application fields, plastic film screen changers can also be used in the production of various high-performance films, nonwoven fabrics, packaging materials, rubber products, and drawn wire products. These products have high requirements for the purity and uniformity of the melt, making the application of screen changers particularly important.
Specific Material Applicability
Screen changers can be used to filter any type of polymer, rubber, or ceramic melt, including but not limited to EPS, XPS, rubber, EVA, GPPS, ABS, PS, PMMA, PET, PA, PPA, PC, PP, PE, PEEK, PBAT, PLA, and other melts. This makes screen changers widely applicable in the plastic processing industry.
In summary, plastic film screen changers have a wide range of applications in polymer molding production lines, plastic recycling and granulation, extrusion laminating production lines, and many other fields. Their application scope covers a variety of plastic and rubber melts, providing important quality assurance for the production of plastic products.
