25 EVENT PREVIEW PETplanet Insider Vol. 25 No. 03/24 www.petpla.net Systems enhancing plastic industry efficiency Eisbär, a leading manufacturer of auxiliary equipment for the plastics industry, has unveiled a range of cutting-edge systems aimed at bolstering quality and productivity in plastic manufacturing processes. Specialising in solutions to prevent condensation on cooled moulds and facilitate the drying of plastic resin, Eisbär’s systems are engineered to handle high throughputs of up to 5,000 kg/h. As the demand for recycling post-consumer plastics continues to surge, Eisbär has developed specialised systems tailored to meet the unique requirements of recycled plastics. These systems efficiently process flakes, clean different materials, and contribute to the production of higher-quality regranulated plastics. The Eisbär Crystallizer: An essential component for processing amorphous PET flakes, the crystalliser treats flakes in a hopper with rotating stirring, achieving optimal results at temperatures between 130-140 °C for 1-3 hours. Eisbär dryer GDS: Crucial for residual moisture adjustment and material cleaning, the GDS dryer employs advanced drying technology with a slowly rotating adsorption wheel with honeycombed tunnels, achieving a residual moisture level of 30 ppm. Eisbär mixing and dosing units: Available in gravimetric or volumetric options and various sizes, these units are claimed to be essential for mixing virgin and recycled materials to achieve good product results, especially for converters using recycled materials. Eisbär conveying systems: The company’s expertise enables conveying of up to 5,000 kg/h for all free-flowing materials, accommodating variations in bulk density, flow properties, and dust content. Eisbär operates a state-of-the-art testing centre where customers can conduct comprehensive tests with granules or flakes. Materials are processed in a material dryer for a specific time and temperature, then analysed for contamination in a chemical institute. www.eisbaer.at Closure advancements for enhanced cycle times This year, Z-Moulds and Eisbär once again share a joint booth at Chinaplas. Z-Moulds will spotlight closure advancements and new technologies aimed at enhancing competitive advantage in cycle times and mould dimensions. In the realm of closure developments, the company is highlighting the 26mm GME 30.40, a solution poised to shape the future, alongside lightweight solutions for CSD closures. When it comes to novel technologies, Z-Moulds will be introducing their new pitch size. The 55mm Pitch, featuring patented z-slides, has enabled the construction of a 128-cavity mould measuring 696mm in width and 1.196mm in height. This reduced the closure’s fall height, compared to the market standard, by almost 500mm, resulting in a 0.12 second decrease in fall time. Additionally, the weight of the moving half was decreased by 45%, compared to market standards that contributed another 0.08 second reduction in opening/closing times. These advancements collectively enable Z-Moulds to achieve lower cycle times. For instance, the cycle time of a 26mm flat water closure could be reduced to 1.85 seconds. www.z-moulds.com Z-Moulds Hall 2.1 Booth A52 Eisbär Hall 2.1 Booth A50 PET crystalliser
