Description

Product description  The small film blowing machine refers to the technological process that the double-folded plastic film made by compressed air huffing, vane cooling and frequency conversion traction and the plastic melt being extruded through dies at a certain temperature and certain cutting force. The small film blowing 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. Product overview Single Screw Extruder 1、Screw diameter：20 2、Length diameter ratio：1：28 3、Screw speed：0-150rpm frequency control 4、Screw material：It is made of 38CrMoAlA chromium-molybdenum steel. With the surface-layer processing of tempering, nitriding, chroming, polishing and super-precision grinding, the hardness HRC55~60, roughness Ra≤0.4μm, nitriding depth≥0.6mm. 5、Barrel material：It is made of 38CrMoAlA chromium-molybdenum steel. With the surface-layer processing of tempering, nitriding, chroming, polishing and super-precision grinding, the hardness HRC55~60, roughness Ra≤0.4μm, nitriding depth≥0.6mm. 6、Heating zone：Mica heaters in 3 areas of charging barrel and in 2 areas of handpiece.
