KHS offers new technology


KHS is introducing a technology which can produce PET containers with a clip-on grip. Here, bottlers are set to profit especially from the great reliability of the established stretch blow molder. The innovative KHS process can be easily integrated into the new InnoPET Blomax Series V. Through its holistic Bottles & Shapes™ consultancy program KHS also helps its customers to develop customized, sustainable containers. These big containers are chiefly used to bottle juice, oil, milk and home and personal care products. 
KHS’ active molds differ from conventional blow molds in that they are equipped with two additional moving mold elements. These can be activated pneumatically to form mounting points for a stable grip on the container during the stretch blow molding process. The handle grip is clipped onto these two points later on in the process. Precise timing of the extension of the mold elements is essential if containers of perfect quality are to be manufactured.
Besides its extreme precision the very low energy consumption of the nextgeneration of KHS stretch blow molders makes it particularly compelling. Thanks to its optimized near infrared heating concept and new Double Gate technology the Series V consumes up to 40% less energy. The air management system for heater box cooling has also been optimized. The air flow can now be set separately for the neck, reflector and lamps. This means that the machine only cools the parts of the preform which actually need cooling. The InnoPET Blomax Series V also scores on performance with an output of up to 2,500 containers per hour and blow station. Furthermore, the stretch blow molder has been designed so that it can process preforms which contain up to 100% recyclate.
Not only owners of the current generation of stretch blow molders benefit from these energy-saving further developments. Users operating a Series IV Blomax can also make use of the latest KHS technology as it can be easily retrofitted. KHS provides its customers with assistance in all aspects of bottle design. With its holistic Bottles & Shapes™ service the Dortmund systems supplierenables customized bottles to be developed. A line-compatible concept such as a PET container with a clip-on grip is just one of many examples. During realization of a design aspects of cost and sustainability are taken into account alongside marketing criteria and user handling. At the moment KHS is working together with a Chinese customer to produce an extremely sustainable large container made of PET, among other ideas, the company reported.
