FAQs
-
Q: What is a melt filter?A: A melt filter is a piece of equipment designed to ensure melted plastic is free of impurities by removing contaminants. Melt filters are also known as “screen changers”.
-
Q: What is the screen changer in an extruder line?A: The screen changer in an extruder line removes contaminants from the melted plastic, as explained above. Plastic extrusion is just one process in which screen changers are used. Screen changers are also used during polymerization, polymer compounding and plastic recycling processes.
-
Q: What is the difference between automated and manual screen changers?A: Automated screen changers automatically rotate new screens into place, whereas manual screen changers require manual rotation.
-
Q: What is the difference between continuous and discontinuous screen changers?A: When you use a discontinuous screen changer, the production process needs to be interrupted for screen changes. With a continuous screen changer at least one screen cavity remains active during the production process while other screen cavities are moved out of the housing for screen changes, so you do not need to stop production.
-
Q: What is melt filtration?A: “Melt filtration” and “polymer filtration” are terms that refer to the process of removing impurities from melted plastics using screen changers or melt filters, as explained above.
-
Q: What industries use melt filters?A: Our screen changers are used by plastic converters working towards products used in a variety of industries, including in packaging, construction, and automotive applications. We welcome you to get in touch to learn more about which of our polymer filtration technology is best for your application.
-
Q: What is Polymerization?A: Polymerization reactions are essentially the process of producing plastics (virgin/virgin polymer). They enable the formation of long carbon chains, which are the basic structural elements of plastics. Polymerization reactions produce products such as polyethylene, polypropylene, polyvinyl chloride (PVC), nylon, and many other plastics used in various applications. BKG® melt filtration systems are used to produce virgin material, removing even the smallest impurities and ensuring high-quality products.
