MOULD MAKING PETplanet Insider Vol. 22 No. 09/21 www.petpla.net 21 The use of High Speed Cutting machines can dramatically reduce the processing times for mould parts and almost completely cut down the manual polishing work of the inner surfaces of those mould parts. Small- est details and complex geometries may directly be produced with this specialised machinery and time- consuming die-sinking (EDM) work is avoided. EISBÄR TROCKENTECHNIK GMBH / Wuhrmühle 22 / 6840 Götzis / T +43 5523 55558-0 / F –50 / [email protected] / www.eisbaer.at GDS GRANULE DRYING SYSTEM 94 % WATER SAVING We took a closer look at our GDS granule drying systems. The result is astounding. We were able to reduce the cooling water consumption drastically. You are having a GDS granule drying system from Eisbär and would like to take advantage of the savings? Please contact us: [email protected] As example for GDS1100: New water consumption litre per minute 12 Water saving litre per hour 9,180 Water saving litre per year 78,030,000 Calculation based on an assumption of 8,500 operational hours per year and a cooling water temperature of 12 °C.

If nec- essary, it takes only a few days from the design stage to an initial sample mould to be completed. Processes within the plant are carefully time and quality monitored and supervised. In case a customer requires a sudden change, for example in priority, pro- duction may immediately react. In most projects, customers usu- ally come up with a suggestion for a bottle design and already send a detailed construction (CAD file). Then Röders with its comprehensive experi- ence consults with respect to feasi- bility in PET stretch blow moulding. Sometimes, the customer only has a vague idea about a bottle design, may be a sketch. Then Röders will develop also the construction of the new PET bottle suitable for stretch blow moulding. Technical require- ments like top load, minimum weight, choice of preform etc. are considered. For testing Röders has a fully certi- fied blowing laboratory, in which also larger numbers of sample bottles may be produced and tested. Renowned companies like PepsiCo and Coca- Cola have certified Röders’ capabili- ties and laboratory. A very important trend in the indus- try with respect to saving resources has been the development of bottle designs for low-pressure stretch blow moulding. This mainly concerns the base design. Again, Röders has made own developments and brought down the blowing pressure to approx. 20 bar helping the customers to achieve significant energy savings. Today, Röders produces an aver- age of 6,000 moulds/year. Business has been stagnant during the year of Covid. When answering the classic parting question “Where will Röders be in five years’ time?” Mr Röders did not mention any specific targets but said “We are flexible, follow the market and remain open for new opportunities. This has been our solid business foundation for more than 200 years company history”. www.roeders.de It is not only the very rapid production that ensures short delivery times, but also the company’s flat hierarchical structure.
