WITH energy prices rising steeply, companies like automotive component, technical and packaging manufacturers which use plastic injection moulding have had to relook at the sustainability of their operations and introduce energy efficiency wherever possible.
Traditionally, the power consumption of a typical injection moulding machine is less than 50% of the total consumption of the entire plant, says strategy and operations executive at GreenTech Plastics Machinery, Marcus Visser.
“When we look at energy efficiency, we need to consider the entire injection moulding system. Our aim is to find the most efficient solution for our customers’ requirements,” says Visser. Combined with integrated temperature control solutions and intelligent device communication, Engel technology from GreenTech can save up to 67% in electricity costs and significantly reduce carbon dioxide emissions.
Engel engineers and developers have greatly reduced the power consumption of the company’s injection moulding machines in recent years. Servo-hydraulic machines already consume less than 60% of a hydraulic injection moulding machine with a variable pump. On average, power consumption can be more than halved thanks to all-electric injection moulding machines.
“When it comes to supplying our customers with injection moulding machines, we have defined efficiency packages,” explains Visser. These packages consist of integrated temperature control and smart assistance systems to reduce power consumption.
