Lab Film Blowing Machine

Lab  film blowing machine / Equipment control The blowing film machine consisted of single screw extruder and film blowing tower, it is mainly used for testing the film blowing feasibility of polymer materials and the colloid status contained in the materials. The extrusion blowing fim machine is refers to the technologicalprocess that the double-folded plastic film made by compressed air huffing,vane cooling and frequency conversion traction and the plastic melt beingextruded through dies at a certain temperature and certain cutting force. Parameters: 1. Single screw extruder  Screw diameter  Φ 20   Length diameter ratio  1:28  Screw speed                                    0 - 95 rpm frequency control  Screw/Feeding barrel material: 38CrMoAl chromium-molybdenum steel.With the surface-layer processing of tempering, nitriding, chroming, polishingand super-precision grinding, the hardness HRC55~60, roughness Ra≤0.4μm,nitriding depth≥0.6mm. Electric control system: PID/LED/RKC intelligent digital display temperaturecontroller, precision smart digital instrument control and display of allprocess parameters, including temperature control, drive, pressure, jointcontrol interlock function.
