A method and a device for processing preforms which are made of a thermoplastic plastic material and are blow molded into containers. In a first production process, the preforms are produced by injection molding in the area of an injection molding tool. At least some areas of the preforms are impinged upon by a cooling device. The preforms are deformed by applying negative pressure, wherefore the cooling device can be made at least in part of a porous material.
