Festo production and integrated energy optimisationFesto decided to set up a plant with a completely new polymer production facility and a focus on energy efficiency, the Global Production Centre Hassel, at its St. Ingbert location in the Saarland. The plant is currently under construction and will be finished in early 2015. All the important factors in terms of the building, production and machines are taken into account here. "Thanks to its many years of know-how in this sector and its holistic approach, Arburg was an important advisor and partner for Festo in this area. We jointly examined the 45 Allrounders for thermoplastic and 12 vertical Allrounders for elastomer processing in detail with regard to energy requirements and production efficiency. Arburg was then tasked with devising optimal machine concepts. For the thermoplastics, electric Allrounder Alldrive machines were selected, which were specially configured to meet the requirements at the Hassel plant. For the elastomers, the machines are to be converted to speed-regulated pump drives.
The key elements of the holistic concept also include insulation of moulds and plasticising cylinders, optimisation of material pre-drying and supply through an efficient central solution and waste reduction, e.g. through lower sprue weights and fewer hot runner connections. Due to the nature of the products, the temperature levels were selected so that cooling is only necessary during midsummer, meaning that heat recovery can be dispensed with.
