FANUC is experiencing an increase in demand for their ROBOSHOT ALPHA-S CNC injection molding machinesthatEnergy conservation B. These all-electric machines consume up to 70% less energy compared to hydraulic presses. This is thanks to the presence in ROBOSHOTs of highly efficient servo motors. This technology also makes it possible to perform parallel movements and reduce the cycle time.
So, ROBOSHOT electric injection molding machine helps to reduce the concerns of companies in the plastic processing industry related to energy consumption and rising prices.
Expensive energy and plastic: it is possible to save with FANUC
The crisis in energy prices actually has strong consequences for the plastics sector; the plastics processing industry is actually a very energy-intensive sector, both from an electrical and thermal point of view. The companies’ requirements are therefore: to save.
As pointed out in an official note to the press by Andy Armstrong, European Sales Manager for FANUC’s ROBOSHOT: «Electric injection molding machines typically use up to 70% less energy than similarly sized hydraulic alternatives, without even considering their cooling needs. Hydraulic machines’ consumption of cooling water has a significant influence on operating costs. FANUC motors, on the other hand, are air-cooled, eliminating these costs. In addition, hydraulic machines typically consume electricity due to energy transfer and oil passage. In the cases where technology without a servo motor is used, the energy consumption is even higher due to the constant operation of the pump motor. This is not the case for fully electric presses. In addition, the lower mechanical complexity of all-electric injection molding machines makes it possible to reduce the stages of the production process and waste of energy.“.
Fully electric presses: even faster return on investment
With the significant increase in energy costs across all industries, the effective payback periods for these presses have been reduced. In addition, faster cycle times, reduced maintenance costs and increased yield allow you to significantly reduce unit costs of parts. With this in mind, injection molding machine manufacturers can no longer ignore the shift to all-electric technology. When longevity and reliability are added, the long-term savings are potentially very high.
Another aspect to keep in mind is the ability to energy regeneration of the FANUC ROBOSHOT presses. When an axis decelerates, the energy goes back into circulation, increasing the overall savings. Users can easily verify that the total operation of two or three ROBOSHOT presses corresponds to the same total electricity consumption as a hydraulic model.
Benefits in the short and long term
ROBOSHOT users can rely on all the proven benefits of these machines: precision, repeatability, part quality, quiet operation and low maintenance. The latter is part of the characteristics that have always characterized FANUC: reliability and longevity. Some customers in Europe have had ROBOSHOT machines for more than 15-20 years with an annual consumption cost of less than 200 euros, allowing them to get the lowest TCO (total cost of ownership) of the market.
As Armstrong concluded: “Ultimately, any company that intends to remain profitable while trying to tackle expensive energy should refocus its investment plans on injection molding machines with a proven ability to reduce electricity consumption. After all, every euro cent spent is a cost. For this reason, it is necessary to carefully identify where savings can be made and focus on reducing overall costs. This is even more important when considering the current trend of rising energy costs, which could potentially continue for some time“.
