Lab small desktop casting film extrusion machine is composed of precision single screw extruder, stretch film die, salivate, winding system and measurement and control system, etc, which can realize high polymer extrusion, stretch film, cutting edge, Rewind and other functions.

We should keep to the fields such as the molding of flow film products, the formulation of flow film materials, the research on the properties of flow film materials and so on, such as the material transported to the flow mechanism and the thin film products etc. Wide application of materials

Such as universal plastic PE PP PVC, engineering plastic PET PA PPS PEEK, elastomer TPU,TPE, etc.

Torque rheometry has proven itself a valuable tool for studying multicomponent thermoplastic systems to assess processing behavior. Torque rheometry measures the viscosity-related torque generated by the resistance of a material to the shearing action of the plasticating process. Typical analyses include the study of processing behavior, influence of additives, thermal sensitivity, shear sensitivity, compounding behavior, and others. Torque rheometry is therefore an excellent tool in helping determine the most process-stable formulation (resin, color concentrate, and additives) for your process. It is also often used successfully in trouble-shooting unwanted degradation and gel formation problems.

The principle of plastic film stretching is to melt the polymer resin through the extruder and extrude thick sheets at the glass transition temperature. In the high elastic state of the polymer under the appropriate temperature range of the upper melting point, the vertical and horizontal puller are successively advanced along the longitudinal and transverse direction under the action of external force a definite multiple of stretching, so that the molecular chains of the polymer are oriented and ordered in the direction parallel to the plane of the film; The orientation of the macromolecular structure is fixed by heat setting in the tensile state. Finally, the ideal plastic can be made by cooling and subsequent treatment

Extruder originated in the 18th century and is one of the types of plastic machinery. Based on the material flow direction of the nose and the screw ZX line, the extruder nose can be divided into the right Angle nose and the inclined Angle nose. Screw extruder is the use of screw pressure and shear force generated by screw rotation, can fully plasticizing and uniform mixture, rely on the mouth molding
