Technological further development makes new designs and high quality possible in the production of

Kobra Formen GmbH, 08485 Lengenfeld, Germany


The product development trends in recent years make new technologies and manufacturing equipment necessary for the production of concrete goods. The Hotshoe™ technology represents the technological further development of an old production trick for reliable manufactur - -ing in the production tools of the concrete goods manufacturers – i.e. the moulds. High quality products, such as structured paving designs resembling natural stone, can be manufactured with the heated pressure plates of the Hotshoe moulds. Mixed layouts which are complicated to manufacture are implemented reliably and paving slabs measuring up to 1,200 x 1,000 mm can be produced with minimised scrap. The facing quality of dummy joint designs with deep-drawn chamfers is impressive and sandstone-like facing recipes in the fine-grained range are easier to implement. Desirable high w/c ratios in products for further refinement can be achieved without adhesion. The scrap rate due to adhesions at the point of demoulding, such as ‘lifters’, ‘pimples’ and ‘micro-tears’, are drastically reduced. The areas of application have become more varied due to new products and prove the ever broader manufacturability of quality products.
