The screw barrel is one of the necessary components of plastic processing machinery. It is the ultimate requirement of plastic processing type machinery. The production process cannot be completed without using a screw barrel. This tool ensures that the product is smooth and the output reaches the expected speed.
Choosing the right screw and barrel is not as simple as it seems. Manufacturers must consider many factors when choosing a suitable screw and barrel, such as cycle time, heat, melting temperature, machine size, recovery time, etc. All these factors play a vital role in influencing product materials and industry standards.
Screw and barrel manufacturers often skip the process of upgrading screw and barrel components to the latest technology. Especially when manufacturers want to upgrade their existing machines, they need to find a screw barrel of the right size and other functions to maximize output.
In today's highly competitive global market, plastic processors can gain an advantage by incorporating relatively simple practices into their operations. The main components of the plasticizing device should be designed to provide maximum melting efficiency at the original gap between the inner diameter of the barrel wall and the outer diameter of the screw thread. These gaps are usually small to achieve good heat transfer and shear rates.
