Abstract
This machine is composed of one or more premoulding moulds in an interchangeable relationship with one or more final-moulding moulds, in which premoulding moulds the resin is injected so that it can be subjected to a thermal conditioning which gives rise to the change from the thermoplastic state to the thermoelastic state by virtue of the formation of an injected preform in a tubular chamber of large surface area and reduced thickness, said first moulds being equipped with a mechanism which extrudes the resin in the form of solid macaroni (a closed trough). The final blow-moulding moulds receive the resin by extrusion, the latter adopting, in principle, a spherical shape and it is optionally moulded, with the collaboration of a movable- bottom base which attracts the hollow body during shaping. This machine makes it possible to carry out moulding with a reduction in terms of time and energy.
