Application of Bimetallic Screw And Barrel

Bimetallic screw and barrel are widely used in the plastic processing industry for the extrusion of plastic materials. The main advantage of bimetallic screw and barrel is their ability to withstand high temperatures and pressures, which are common in plastic processing. Here are some of the common applications of bimetallic screw and barrel:
Extrusion of thermoplastics: Bimetallic screw and barrel are used for the extrusion of thermoplastics such as PVC, HDPE, LDPE, PP, etc. These materials require high temperatures and pressures for extrusion, and bimetallic screw and barrel can withstand these conditions for a longer time without wearing out.
Extrusion of thermosets: Bimetallic screw and barrel are also used for the extrusion of thermosetting materials such as epoxy, phenolic, and melamine. These materials are highly viscous and require high temperatures for processing, and bimetallic screw and barrel can provide the necessary thermal stability.
Blow molding: Bimetallic screw and barrel are used for the extrusion of plastic materials in blow molding applications. Blow molding is a process where plastic materials are blown into a mold to create various shapes and sizes of products such as bottles, containers, and tanks.
Injection molding: Bimetallic screw and barrel are also used in injection molding applications, where molten plastic is injected into a mold to create products such as automotive parts, toys, and household items.
In summary, bimetallic screw and barrel are essential components in plastic processing industries, and their application is vast. They provide thermal stability, durability, and longevity in processing high-temperature and high-pressure materials, resulting in high-quality plastic products.
