Lab film blowing machine / PLC control Extrusion film blowing 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. The film blowing machine consisted ofsingle screw extruder and film blowing tower, it is mainlyused for testing the film blowing feasibility of polymer materials and thecolloid status contained in the materials. Parameters: 1. Single screw extruder Screw diameter F 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: PLC programmable color touch screen,man-machine interface operation system, can dynamically display and monitorextrusion process, including temperature control, driving, pressure,interlocking spreading function. 2. Film blowing tower Diameter of dies F 30 Driving rolling speed 0- 5 m/min adjustable Maximum folded diameter of the film 150 mm Servo motor 90 W Fan 0.25 KW Rolling torque motor 3.5 N.m Illuminating case LED light Huffing air: Compressed air 0 -6 bar, can be fineadjusted and stabilized. Cooling air: Blower flow 30 L/min, can be fine adjustedand stabilized. Features ¦ Thismachine has compact design and a small body, not occupying too much indoor area. ¦ Thehost and auxiliary machines are of easy assembly with few raw material. Themaximum folded diameter of the thin film can reach200mm. ¦ Thismachine is equipped with the C-type fastchanging handpiece of easy operation and time labor-saving test. ¦ Single-layeror double-layer cooling vane and the closed-loop control of creasing width ensure reliable product quality. ¦ Thespiral circulation film blowing die of high performance is easy to clean andmaintain. ¦ Theheight of the filming blow tower can be adjusted arbitrarily to meet testrequirements. ¦ Theextrusion, traction and rolling have the property of stepless speed regulating,ensuring requirements of film blowing technology to be met.
