A new type of melting sheet machine plasticizing technology led to a new era

Using sheet machine, and we have most of them are on plastic extrusion, so this kind of machine also known as extruder. This machine can pass the collocation of different screw, produce the different specifications of the material. And in recent years, there is a kind of super shear plastic sheet machine industry is the hottest topic, also is melting plasticizing technology. The plasticizing extruder based on new materials, completely abandoned the traditional screw extruder based on transport and plasticizing mechanism of the shear and friction, but the transport mechanism based on normal stress effect. The plasticizing extruder extruder by several groups of blade unit series, and each set of blades of plastic extrusion unit structure is similar to the vane pump, the hydraulic system is composed of pump body, the eccentric rotor and blade. Work material from the big end of eccentric cavity, and then to the cavity driven by blade and extrusion unit to the next, small end material completely under the function of normal stress during grinding, compaction, exhaust and plasticizing, this principle also makes the system cup machine has changed. This material is lost in the process of traffic volume is determined by the volume change of the midplane pump body, transport efficiency basically is not affected by material of rheological properties. Therefore in the process of extrusion extrusion quantity is affected by the die head pressure is small, hard extrusion characteristics. And residence time of the material in the extruder is more uniform, reduced the material difference of thermal process. This technology led to a more efficient production, in addition to being able to reduce the material difference of thermal process, also can improve the efficiency of a certain production, for the production principle of the past is a kind of brand-new 'change', leading the sheet machine to the new era.
