  1. Anglicky v odborných předmětech"Support ofteachingtechnicalsubjects in English“ Tutorial: Engineering Technology Topic:Plastic V. - Extrusion + blowing Prepared by: Ing. VladislavZelinka Projekt Anglicky v odborných předmětech, CZ.1.07/1.3.09/04.0002 je spolufinancován Evropským sociálním fondem a státním rozpočtem České republiky.

  2. EngineeringTECHNOLOGYPlasticExtrusion + Blowing

  3. Briefly: Extrusion is most often used for production of profiles with hollow inside as well. Process is continuous and plastic profile is then „neverending“. Various flat foils, boards or tapes can be also extruded. Blowing is used for products which have shape of tanks, cans or barrels. Process concurs on pipe extrusion which are blown while warm until they have shape of split form.

  4. Extrusion /blowing – hollow products: Take out Pipe extrusion Blowing and setting Compressed air Product Plastic pipe Profile nozzle Blowing hose Split mould (cooled) Extrusion and blowing of hollow products

  5. Profile extrusion: Steering warm Cutting machine towbar Filling funnel Calibrating pipe cooler Shaping extension Hollow profile heating profile profile Granulated plastic Compaction cylinder Compressed air Line for production of hollow plastic profiles by extrusion

  6. Using of extruded pipe as an intermediate material. Flatwise folded hollow foil Draw pulleys Flat boards Idler pulleys Rim cutter Hose inflating to Reel Air cooling Circular nozzle Shaping extension Inflatable air Liquid plastic Foil production by blowing extruded hose

  7. Summary: Extrusion is most often used for production of profiles with hollow inside as well. Process is continuous and plastic profile is then „neverending“. Various flat foils, boards or tapes can be also extruded. Blowing is used for products which have shape of tanks, cans or barrels. Process concurs on pipe extrusion which are blown while warm until they have shape of split form.

  8. ACTIVITY I.: Decide and choose the best solution of the problem: 1.) Product will have very thin and almost evenly thick wall of round shape , 2 liter capacity. Will you use foaming? Yes / No / It isn´t easy to determine 2.) Product will have opposite (negative) full shape of counterpart 0,2 x 0,5x0,9 meter and should absorb possible strokes. Will you useblowing? Yes / No / It isn´t easy to determine

  9. ACTIVITY II.: Decide and choose the best solution of the problem: 3.) Product will be transparent and will have shape of containment of ceiling light with fluorescent bulb. Will you use presswork? Yes / No / It isn´t easy to determine 4.) Product will have a shape of very thin and long foil (film). Will you use rolling? Yes / No / It isn´t easy to determine
