Résumé : |
Energy will not become cheaper in the long term – and it is usually one of the most important cost factors in plastics processing. In addition, the topic of sustainability is trickling into everyday life on a broad front, equally among legislators and consumers. Reasons enough to improve energy efficiency in the company. Even with supposedly modern equipment, material logistics usually offers a wealth of possibilities. |
Note de contenu : |
- Use material throughput fluctuations during drying
- Dry air generation and dehumidification
- Control according to demand
- Conveying more energy-efficiently
- Adjusting air volume and speed
- Alternative: permanent central vacuum systems (PCVS)
- Digitization helps
- Fig. 1 : The complex material logistics in injection molding offer many possibilities for reducing energy consumption
- Fig. 2 : Fluctuations in material throughput reduces energy consumption thanks to rapid adjustment of the air volumes to the drying bin. In addition, lower air volumes are gentle on the material
- Fig. 3 : Maximum energy efficiency and at the same time optimum material drying under all boundary conditions, even with extreme fluctuations in material throughput, is offered by the combination of rapid adjustment of the air volume and the heating temperature in the drying bin
- Fig. 4 : An optimum, uniform vacuum level which minimizes peaks reduces energy consumption and protects the granulate
- Fig. 5 : The permanent central vacuum system (PCV) enables energy savings of 30 to 50 % compared to line systems, offering significantly higher operational security, and lower maintenance requirements as well as requiring less floor space |
