PLC Control Lab Film Blowing Machine

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  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: 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.
