Have you ever stopped to wonder how those plastic bags, toys, and even parts of your home appliances are created? One key machine used to produce these items is known as a co-rotating twin screw extruder. Fairly complex, but let’s simplify it.
A co-rotating twin screw extruder is a unique machine that combines materials — plastic, say, or rubber or food ingredients — using two long screws. These screws rotate in the same direction and cooperate to urge the materials through the device. As the wraps pass through, they are warmed and melted, which allows them to transform into new forms.
Now that you have an understanding of this machine, let’s cover why it’s great to be able to use. One huge plus is that it blends materials very thoroughly, ensuring the end result is strong. Another advantage is that it’s fast, Keyser said, which can be important for companies that need to produce a lot of product quickly.
What is the difference between a co-rotating twin screw extruder and a counter-rotating twin screw extruder, some of you might ask. The key difference is in the direction the screws turn. In co-rotating and counter-rotating twin screw extruders the screws rotate in the same and in opposite directions, respectively.
Co-rotating twin screw extruders are sometimes used, because materials tend to mix more easily while accommodating various types of materials. Counter-rotating twin screw extruders excel at forcing materials though at a faster rate.
Co-rotating twin screw development: an innovative creation that has revolutionized the plastics industry. It used to be difficult to mix things and make good plastic products without this technology. Now, with the new co-rotating twin screw extruders, such companies can produce a wide variety of plastic articles, in much a more economical manner and with improved quality.
Twin screw extruders in co-rotating configuration find applications in a wide variety of industries. For instance, in the food industry, they combine ingredients to produce pasta, breakfast cereals and snacks. In the automotive field, they are used to help fabricate car parts such as bumpers, dashboards and tires.
