Process	Injection blow moulding
	Used for high quality bottles like bottles for mineral water containing CO2 under pressure. First a small part with a large wall thickness (a so-called preform) is produced by injection moulding. The preform is heated and then transferred to the blow moulding machine where it is blown into final shape. Compared to blow moulding, injection blow moulding gives better definition of details (e.g. screw thread), and a better control of the distribution of the thickness of the material.
