Injection moulding machines Spend to save
Today’s injection moulding machine technology is far more energy efficient than that of 20 years ago. At a conservative estimate, modern hydraulic injection moulding machines are 25% more energy efficient than those manufactured in 1997. Meanwhile, today’s best all-electric machines may be up to 80% more energy efficient than their 20-year old hydraulic predecessors. It will pay you to make use of these machinery developments.
Using old machinery is not saving you money; it is costing you more to run your processes and placing your business at a permanent cost disadvantage to competitors.
In almost every case, the cost of energy required to run a moulding machine over a 10-year period will be greater than its initial purchase cost. This cost gap will only widen as energy prices increase. For this reason, energy assessment must become part of the purchasing process for every new moulding machine.
Considering the whole life cost of a machine is difficult but it is the only way to control future energy expenditure. It will help ensure that an attractive low cost machine does not become an energy hog that raises production costs through its entire lifetime.
Remember, there is no conflict between energy management and production rate. Being efficient does not mean slowing the process down; the reality is that the energy efficiency of a plant and its machines gets better as production rate increases because the base load is amortised into a greater process load (explained in the next section).
