The extrusion method of the extruder generally refers to the melting of plastic under the high temperature about 200 degrees, and the melting of the plastic forms the required shape when passing through the mold. Extrusion molding requires a deep understanding of plastic characteristics and rich experience in mold design. It is a molding method with high technical requirements. Extrusion molding is in the extruder through heating, pressure and so that the material flow state through the mouth die molding method, also known as "extrusion". Compared with other molding methods, it has the advantages of high efficiency and low unit cost.

        Extrusion method is mainly used for thermoplastic molding, can also be used for some thermosetting plastics. Extruded products are continuous profiles, such as tube, rod, wire, plate, film, wire and cable coating, etc. In addition, can also be used for plastic mixing, plasticizing granulation, coloring, mixing and so on.

        Extruded products can be called "sections", because the cross-section shape is mostly irregular, so it is also called "profiles".

        Principle and composition of extruder:

        Add water or appropriate liquid to the raw powder and stir it continuously. The mixed material is extruded from the porous head or metal mesh with high extrusion pressure. Usually, the material is put into a cylindrical container and extruded with a screw. With frequency conversion technology, the pressure can be controlled so that a suitable linear speed can be selected.

        An extruder is usually composed of the main machine (extruder), auxiliary machine and its control system. Usually these components are collectively referred to as the extrusion unit.

        An extruder main machine by extrusion, transmission, heating cooling three parts of the system.

        The extrusion system is mainly composed of screw and barrel, which is the key part of extruder. The role of the drive system is to drive the screw, to ensure that the screw in the process of working with the required torque and speed; The heating and cooling system mainly ensures the temperature control of the material and extrusion system in the forming process. Auxiliary machine The composition of auxiliary machine of extrusion equipment depends on the type of products.

        Generally speaking, auxiliary machine is composed of agent penetration setting device, cooling device, traction device, cutting device and winding or stacking device of products. Control system The control system of the extruder is mainly composed of electrical appliances, instruments and actuators. Its main function is to control the driving motor of the main and auxiliary machines, meet the speed and power required by the process requirements, and ensure that the main and auxiliary machines can operate harmonically.

        Control the temperature, pressure, flow rate and product quality of main and auxiliary machines. The ceramic extruder realizes the automatic control of the whole unit. V2 frequency converter is used for extrusion equipment, with high quality operation characteristics, which is determined by the good product performance of vector control frequency converter itself. Fast processor provides higher frequency response V2 converter 32-bit processor, provides high control precision, fast response frequency and good dynamic performance.
