The technology featuring the solar energy storage system described above is being used at Fakuma 2023 to drive the new EcoPower B8X on show at the Wittmann booth. However, in line with the value attached by the company to the energy efficiency theme, it is presenting solutions for reducing energy consumption and lowering greenhouse gas emissions at nine stations, creating an energy efficiency path.
"Take the new EcoPower B8X. The toggle lever of this new all-electric injection molding machine has been kinematically optimized, reducing the force required for clamping force build-up by 15 percent. This decreases the stress on the electromechanical drive system, further reducing the energy consumption, while at the same time enabling a higher level of dynamism and better dry cycle times," Michael Wittmann said.
Wittmann's IMAGOxt energy management software is being used to make the machine's low energy consumption visible, he added. IMAGOxt, a software module to visualize and monitor the energy consumption, enables inefficiencies to be detected and measures to be taken to improve efficiency, uncover potential savings and reduce CO2 emissions.
The module has been optimized to interact with Wittmann's MES operating software solution, TEMI, and can be connected to auxiliary equipment to collect data and analyze factors such as temperature, pressure, humidity, gas consumption and water consumption—assisting customers on the road to implementing the European Union Green Deal and the transition to a more circular economy for plastics.
It is not the only way Wittmann is supporting the circular economy. As a supplier of products, technologies and turnkey solutions for injection molding processing, it has also focused on the need to ensure these are able to produce equally high-quality products from materials other than fossil-based virgin polymers.
"All Wittmann injection molding machines can be used to process both recycled materials and bioplastics," Michael Wittmann said. A key factor in processing alternative materials is the plasticizing unit. The company has the know-how to provide the right screw for every application, even the most demanding, which, in combination with its smart assistance systems that compensate in line for fluctuations in the raw material, ensures consistently high product quality.
Wittmann even produces the granulators needed to shred sprues and rejects directly at the machine, enabling these to be returned to the injection molding process, should the application so permit.
However, while the plastics industry is working very hard to close material cycles, there is still a very long way to go before we can really talk about a circular economy, he noted.
"This is a challenge for everyone—industry, consumers and politicians. We need uniform systems for collecting and processing plastic waste in order to secure a reliable supply with high-quality raw material, and we need even more information for consumers in order to enable them making responsible decisions as early as the point of purchase.
"These are just two of many urgent tasks which only can be solved if society as a whole pulls together. The plastics industry is a strong driver here," he said.
