Quick Details

Product Description

The extruder is a kind of equipment commonly used in the manufacture of plastic products. It heats and melts the plastic and extrudes it through the elements of the screw and screw structure, so that the molten plastic passes through the mold to form the desired shape. Threaded elements play an important role in extruders.
Threaded elements usually consist of one or more screws and threaded sleeves. The screw is the main driving element, which consists of threads and a shaft. The threaded sleeve is the shell of the threaded element, and the threads inside the threaded sleeve cooperate with the threads on the screw to form a spiral channel.
During extrusion, the screw rotates to push the molten plastic forward. When the molten plastic passes through the screw channel, the screw thread of the screw element will form a channel that gradually shrinks due to the gradual decrease of the pitch of the screw thread. This structure can realize uniform extrusion of plastic and increase extrusion pressure.
The design of threaded elements is usually determined by the desired product shape and properties. For example, if a plastic product needs to be manufactured with a specific thread shape, the thread shape of the threaded element will match it. Threaded elements can also be customized according to extruder specifications and requirements.
In general, the extruder building block screw element refers to the thread structure composed of multiple components, which plays the role of extruding the plastic melt into shape in the extruder. This design makes the threaded elements more flexible and can be adjusted and combined as needed to meet the extrusion requirements of different products.
