It combines the precision of injection moulding with the shaping capability of blow moulding. By injection moulding a so-called “preform”, the injection moulded container is provided with an opening (screw closure) with injection moulded quality. Other advantages are adherence to uniform wall thicknesses, waste-free manufacture, no seams in the neck and base area (can therefore be subjected to pressure) and outstanding surface quality.

Injection blow moulding systems consist of a plasticizing unit, a temperature control station (if required) and the inflation station. The preform is created by injection moulding onto a core. This remains on the core when it is removed from the mould, and is then inflated to the final shape in the thermoelastic temperature range in a blow moulding tool.

Hollow container moulded parts up to a capacity of about 2 litres are produced. The most frequent applications are bottles and crucibles for pharmaceuticals, cosmetics and also the food industry.
