In high-end manufacturing, precision is not a selling point—it is a requirement. Optical components, electronic connectors, medical devices, and critical automotive structural parts leave no room for variation. A difference of a few hundredths of a millimeter can mean the difference between a premium product and a rejected part.
At Guangdong Lixun Machinery Technology Co., Ltd., we understand that precision begins with the machine. That is why our full electric injection molding machines are engineered for higher accuracy and repeatability—delivering the control, consistency, and confidence that demanding applications require.
The Core Advantage: Higher Precision and Repeatability
The defining feature of our full electric injection molding machines is their core advantage: superior precision and repeatability.
This precision is not the result of clever software alone. It is built into the physical architecture of the machine—and it starts with how motion is generated.
Direct Servo Drive: Eliminating the Sources of Variation
A traditional hydraulic injection molding machine controls motion indirectly, through oil pressure and valve response. This introduces multiple sources of variation that no control system can fully compensate for:
Oil temperature changes – As hydraulic oil heats up, its viscosity drops, changing flow rates and response times.
Oil viscosity variation – Different oils, different ages, and different operating temperatures all produce different behavior.
Hydraulic leakage – Internal leakage in valves and cylinders causes position drift over time.
Valve response delay – Hydraulic valves take time to open, close, and change direction, introducing lag and overshoot.
Our full electric injection molding machines eliminate all of these variables at the source. Each motion is driven directly by a servo motor, coupled through ball screws, belts, or gear transmissions. There is no oil to heat up, no viscosity to change, no leakage to drift, and no valve to lag.
The result is motion that is precise, immediate, and repeatable—cycle after cycle, hour after hour, day after day.
Critical Parameter Control: Precision Where It Matters Most
The precision of a full electric injection molding machine is not a single specification. It is a collection of tightly controlled parameters that together determine part quality. Our machines deliver exceptional control across the parameters that matter most:
Injection Speed — Especially Multi-Stage Precision Control
Injection speed directly affects fill patterns, shear rates, and molecular orientation. Our full electric injection molding machines provide precise, programmable multi-stage injection speed profiles—allowing you to tailor the fill process to the part, not the other way around.
Smooth transitions between stages
Accurate speed holding at each stage
Repeatable profiles from cycle to cycle
Holding Pressure Switchover
The transition from injection to holding pressure is one of the most critical moments in the molding cycle. Too early, and the part shorts. Too late, and the part flashes or builds stress. Our full electric injection molding machines execute this switchover with precision and repeatability, using position or pressure-based control as required.
Position Control
Clamp position, injection position, ejection position—every position is controlled by servo motors with high-resolution feedback. This means:
Accurate mold closing positions
Precise injection stroke control
Repeatable ejection positions
Metering (Plasticizing)
Consistent shot size begins with consistent metering. Our full electric injection molding machines control screw rotation and back pressure with servo precision, delivering uniform melt quality and repeatable shot weights.
Mold Opening and Closing Positions
Accurate mold position control protects the mold and ensures consistent part release. Our machines deliver smooth, precise, and repeatable mold motion—every cycle.
Why This Matters for Demanding Applications
The precision and repeatability of our full electric injection molding machines are not abstract specifications. They translate directly into success in the most demanding applications:
Optical components – Lenses, light guides, and precision optical parts demand exact dimensions and minimal stress. Our machines deliver the control these parts require.
Electronic connectors – Fine pitch, thin walls, and tight tolerances leave no margin for error. Repeatable injection and holding control are essential.
Medical components – From syringes to surgical instruments, medical parts demand consistency, traceability, and zero defects.
Automotive critical structural parts – Under-the-hood and structural components must meet exacting specifications for strength, dimensional accuracy, and reliability.
For these applications—and for large, high-precision products in particular—the difference between a hydraulic machine and a full electric injection molding machine from Guangdong Lixun is not incremental. It is decisive.
Force Control: 0.5-Grade Precision, 3–5 Times Better Than Hydraulic
One of the most impressive technical achievements of our full electric injection molding machines is their force control precision.
Our machines achieve 0.5-grade force control accuracy—approximately 3 to 5 times better than conventional hydraulic machines.
What does this mean in practice?
Low Clamping Force Molding
With precise force control, our full electric injection molding machines can perform low clamping force molding—using only the force actually required to hold the mold closed against injection pressure. This reduces mold wear, lowers energy consumption, and minimizes stress on the machine structure.
Multi-Sensor Force Control on Tie Bars
Our machines use multiple sensors on the tie bars to monitor and control clamping force. This ensures:
Even force distribution across the platen
Accurate, repeatable clamping force
Protection against uneven or excessive force
Longer tie bar and platen life
Independent Injection Force Control
Injection force is controlled independently, allowing precise control of packing and holding pressure. This independence means injection and clamping can each be optimized for the part—without compromise.
0.01 mm Repeatability
The ultimate measure of precision is repeatability—the ability to produce the same result again and again. Our full electric injection molding machines achieve repeatability of 0.01 mm on critical positions and motions.
This means:
Better part detail – Fine features, sharp edges, and precise dimensions are reproduced faithfully.
Higher yield rates – Fewer rejects, less scrap, and more good parts per shift.
Greater customer confidence – Consistent quality builds trust and repeat orders.
