Abstract
This process takes place by means of a mould or set of moulds which constitute thermo-conditioning tubular cavities of large surface area and small thickness, and they receive, injected into them, the resin which reaches a thermal equilibrium which is suitable for changing from the thermoplastic state to the thermoelastic state which allows a biaxially orientated hollow preform to be obtained in such a manner that, using mechanical means inside the mould, the resin is then introduced into the blow-mould or set of blow-moulds facing the aforesaid, and optionally provided with a movable base, the result being a hollow body with regulation of thicknesses. With this process, moulding times are reduced, energy is saved and containers are obtained with a flat base of uniform thickness.
