Electricity is one of the largest operating costs in any injection molding facility. It powers the machines, the chillers, the dryers, the conveyors, and the lighting. And in a traditional hydraulic molding shop, a shocking amount of that electricity is simply wasted—converted into heat, noise, and idling losses rather than into productive work.
At Guangdong Lixun Machinery Technology Co., Ltd., we believe that energy should be spent on production, not on keeping oil pumps spinning. That is why our full electric injection molding machines are engineered with one of the most compelling advantages in modern molding: outstanding energy efficiency.
The Core Advantage: Outstanding Energy Saving
The defining feature of our full electric injection molding machines is their core advantage: exceptional energy saving.
This is not a marginal improvement. It is a fundamental rethinking of how a molding machine consumes power—and for large-tonnage machines in particular, the savings can be transformative.
How It Works: Power Only When It Is Needed
The energy efficiency of a full electric injection molding machine comes down to a simple principle: power on demand.
Hydraulic Machines: Continuous Consumption
A traditional hydraulic injection molding machine relies on a central hydraulic power unit—typically one or more large oil pumps driven by an electric motor.
Here is the critical problem: the pump keeps running even when the machine is not performing a useful action.
During mold closing, the pump supplies oil to the clamping cylinder.
During injection, the pump supplies oil to the injection cylinder.
During holding, the pump maintains pressure.
During mold opening and ejection, the pump supplies oil again.
But during idling, waiting, and even during pauses between cycles, the pump continues to turn—consuming electricity and generating heat without producing any useful output.
This is known as idling loss, and it is pure waste.
Full Electric Machines: Independent Servo Control
Our full electric injection molding machines operate on an entirely different principle.
Each motion unit—clamping, injection, plasticizing, ejection—is driven by its own independent servo motor. These motors consume power only when they are executing an action:
Mold closing – The clamping servo motor draws power.
Injection – The injection servo motor draws power.
Holding pressure – Power is drawn only as needed to maintain the set pressure.
Mold opening – The clamping servo motor draws power again.
Ejection – The ejection servo motor draws power.
Between actions—and especially during standby, waiting, or pauses in production—energy consumption drops to an extremely low level. There is no central pump spinning uselessly. There is no hydraulic oil circulating and heating up. There is no wasted energy at all.
The result is a machine that consumes electricity in direct proportion to the work it actually performs. Nothing more.
The Large-Tonnage Amplification Effect
The energy-saving advantage of a full electric injection molding machine is impressive at every tonnage. But it becomes dramatically more significant as machine size increases.
Why Hydraulic Machines Waste More as They Grow
On a large hydraulic machine—say, 400 tons and above—the hydraulic system must be sized to generate enormous clamping force and drive heavy injection units.
This means:
Larger oil pumps – Bigger pumps consume more power even at idle.
Higher flow requirements – More oil must be moved to drive larger cylinders.
Greater system inertia – Larger volumes of oil must be pressurized and maintained.
Higher fixed losses – The baseline energy required just to keep the system ready grows with machine size.
Crucially, these losses occur whether or not the machine is producing parts. A large hydraulic machine sitting idle still burns significant electricity. A large hydraulic machine running at partial capacity still drives a full-sized pump system.
As tonnage increases, the proportion of fixed loss—the useless work—grows higher and higher.
Why Full Electric Machines Shine at Large Tonnage
Our full electric injection molding machines do not suffer from this scaling penalty.
Because each motion is driven by an independent servo motor, power is delivered only to the axis that is moving, and only for as long as it is moving. There is no central power unit sized for peak demand that must run continuously.
On a large machine, this advantage compounds:
No massive oil pump idling – The biggest single source of waste is eliminated.
No hydraulic circulation losses – No oil to pump, filter, cool, or maintain.
No pressure-holding losses – Clamping force is maintained mechanically, not hydraulically.
No standby consumption – When the machine is not cycling, it draws almost nothing.
This is why the energy-saving effect of full electric technology is most pronounced on large-tonnage machines—and why the financial returns are greatest exactly where energy costs are highest.
30%–70% Energy Savings Compared to Hydraulic Machines
In real-world production, our full electric injection molding machines typically achieve 30% to 70% energy savings compared to hydraulic machines of the same tonnage.
The exact figure depends on:
Machine tonnage – Larger machines tend to show greater savings.
Cycle time – Longer cycles with more idle time favor full electric.
Production pattern – Frequent starts, stops, and pauses amplify the advantage.
Part complexity – Machines with varied motion profiles benefit most.
Ambient conditions – Hydraulic machines lose more efficiency in hot environments.
Even at the conservative end of that range, the savings are substantial. At the higher end, they are transformational.
The Long-Term Financial Impact
Energy savings are not a one-time benefit. They accumulate every hour of every shift, every day of every year.
Consider the math:
A single large hydraulic machine may consume tens of thousands of kilowatt-hours annually just in idling and fixed losses.
Multiply that across a fleet of machines.
Multiply again across years of production.
The cumulative savings from a full electric injection molding machine can easily exceed the initial price difference—often within the first year or two of operation. After that, every kilowatt-hour saved flows directly to your bottom line.
And because electricity prices are volatile and generally rising, the value of energy efficiency only grows over time.

Why Energy Efficiency Matters More Than Ever
Choosing a full electric injection molding machine is not just a technical decision—it is a financial and strategic one.
Lower Operating Costs
Electricity is a recurring, unavoidable expense. Reducing it by 30–70% directly improves your margins on every part you produce.Faster Return on Investment
The energy savings alone can justify the investment in a surprisingly short time—especially on large-tonnage machines.Protection Against Rising Energy Prices
As electricity costs increase, efficient machines become more valuable, not less.Reduced Cooling Load
Hydraulic machines generate enormous waste heat. Full electric machines run cooler, reducing the burden on your chiller and air conditioning systems—and saving even more energy.Environmental Responsibility
Less electricity consumed means less CO₂ emitted. Energy efficiency is one of the most direct ways to reduce your carbon footprint.Competitive Advantage
In a market where every cent of production cost matters, lower energy costs give you room to compete on price—or to enjoy higher profits.
