Clamping Unit:
1. Optimized Platen Design with high rigidity and enlarged space between tie bars
2. Euromap-based Platen Layout with both T-slot & tap holes, locating design in moving platen to better suit various molds
3. New ejection system design with longer ejection stroke, bigger space and better rigidity
4. Hydraulic drivien gear-type mold height adjustion mechanism
5. Relocation of mechanical safety interlock for easier operation
6. linkage structure for front connecting rod increases connectingrod's strength greatly, as well as the whole clamping unit's rigidity & accuracy.

Injection Unit:
1. High Quality Linear Motion Guide ensure the smooth & accuracy of injection process
2. High Speed & Pressure injection structure can improve the injection speed
3. Twin nozzle cylinder ensures more even & stable structure
4. Specilized screw barrel design for various appliance

Hydraulic System:
1. The double proportional compound valve control system pressure & flow, highly sensitive & stable
2. Imported high quality Pump, low in noise, long in lifespan & stable in performance
3. World-famous servo hydraulic system optional, better performance in lower noise & energy saving
4. The precise feedback control of servo system to the pressure & flow, with higher sensitivity & more accurate repeatability precision
5. High performance hydraulic valve, less failure, fast switch, convenient maintenance
6. Low pressure mold protect system, which is more suitable for the precise mould
7. Greese & lubrication oil in dependent lubrication system can lubricate everywhere in the best situation

Electrical System:
1. Control by double CPU, the system with high speed, noise-immunity, fan-less and lower power consumption, independent control structure improve the stablity of control
2. 8.4" display screen with resolution 800*600, user friendly screen & optional choose of language
3. Equiped with USB(2.0) port & ethernet(100-base T) ports
4. 32 Points input & output, entendable and trouble spot can be replaced easily
5. Linder transducer's resolution is 1/65535, more precise in control
6. 120 technological parameters access can be stored & uploaded with an ordinary USB drives
7. Injection End and temperature tracking is curve display, dynamic recorder parameter is modified, dynamic warningis exhibited, all these make the operation more convenient.

Servo Controller Part:
1. High Precise Control
The servo system can control the machine's pressure, speed & location precisely, make sure that the error of  accurate repeatability precision for the shot measurement is <0.3%
2. High sensitive response
Because the motor vector is matched with the controller accurately, it only takes 0.5sec. inputing the number from 0 to max. Compared with other traditional hydraulic injection molding machine, LSF series is more faster in speed with shorter cycle time and high efficient in production
3. Low noise
Compared with traditional fixed pump & variable pump system, the noise is 1/10 lower under normal circumstance, more suitable for sealed dustless workshop
4. Energy Saving
Overall efficiency is 10% more & driving capacity is 18% more than common machine. This series can save 30-80% energy, and achieve first-class energy efficency
5. Water cooling saving
The system condition prevent high pressure uploading without any power output, leads to the water cooling saving
