Aims :

The student will be directed to an analysis of design problems to planning the production of the parts. For manufacture with polymers can be made by different types of conversion in comparison each to another, students must get technical economical evaluations.

Topics :

Main conversion technologies of the plastic at high pressure: compression molding, transfer moulding, injection moulding. Close examination of the technique of injection molding with the study of manufactured articles and with the planning of the technology. Simple numerical exercises of planning the moulding cycles with times and geometrical parameters definition. Mass manufactured articles and semi-expansion parts. Extrusion dies. Extrusion of profiles and cables. Machineries, control's parameters. Point of job of the extruder. Exercises of calculation. Production of containers and of films by extrusion. Method of the conversion by cast film. Gas-assisted technologies. Technologies at low pressure. Thermoforming. Composite materials.
