Design for light-weight products

Kiefer Werkzeugbau, Hall 7 Booth 109

Kiefer Werkzeugbau GmbH based in Schwaigern, Germany, has been active in the mould and die industry for the plastics processing industry for more than 30 years. As an independent mould maker, Kiefer is producing blow-moulds for all common rotary blow moulding machines and for linear blow moulding machines

As the market demands savings in energy and lightweight products, new concepts in bottle design are required. There are various approaches such as the use of a new preform with a reduced thread, or a creative bottle design. The grip and shape stability on a thinner-walled bottle can be achieved by incorporating certain stabilising grooves, shafts, spirals. Here, the developer sets lines, waves and elements in such a way that the height differences haptically achieve a corresponding stability.

Innovative bottom interpretations in the field of light-weight & low-pressure base design with the Pataloid-base and the flat base allow the bottler to reduce the blowing pressure by 30-50%, resulting in huge energy savings. The optimisation of the ventilation system between the bottle and the mould cavity enables faster exhaust of the air with a lower blowing pressure. Air moves in a homogeneous way: vent holes are replaced by lines. The finish of the bottle is improved, with a stronger, yet lighter base.
These specifications of the light-weight & low pressure base design are common to all suitable blow moulding machines.
