Blow molding and thermoforming

Thermoforming and blow molding are among the classic, discontinuous forming processes that have long been established in the plastics industry. In thermoforming, thermoplastic materials are formed under the influence of heat with the aid of compressed air or vacuum. This process is used to produce bathtubs, packaging and automotive components from films or thin sheets, for example. In contrast, blow molding is used to produce hollow bodies, such as bottles and tanks, which are blown from a plasticized plastic tube.

We deal very intensively with the machine technology and the challenging material properties of the plastics used. In particular, the degrees of forming and the resulting wall thicknesses are of great interest for the applications and sometimes require difficult machine and temperature settings. There is also a need for research into the orientation of fillers during processing by blow molding or thermoforming. The machines at SKZ are available to interested companies for sampling or material development at any time. Our experts support the projects with years of expertise. Our knowledge of thermoforming and blow molding is continuously expanded and passed on to companies in the context of advanced training courses.

Many plastics processing companies, just like SKZ, see great potential for innovation here, especially in the packaging sector. We will be happy to support you in your research and development as well as training and further education in this area.
