Product Description

LG has been divided into three groups, LG, LS and GS based on their business specialties in 2003.

We have the Injection Molding Machine as below:
LGH-D Series from 80T~350T,2500T,4000T
LGH-M Series from 450T~1050T

Advantages of our machine:
Rigid Mold Platen
Mold deflection by the clamping force and injection cavity pressure is minimized through developing the high intensive light-weight vacant casting platen having optimum rigidity with 3-dimensional design, which uses the finite-element analysis. 

Less Hydraulic Oil
The hydraulic oil quantity is reduced to less than half of a conventional machine with compact design on dividing clamping cylinder from booster cylinders for the mold movement, and on adopting the high pressure of hydraulic system.

High Productivity
Unique clamping mechanism enables the clamp pressure to increase with four short-stroke clamping cylinders and the high-pressure design, which leads shortening the pressure-up timing and realizes the high cycle by adopting the standard of DBG screw and back-pressure relieving.

Energy Saving
Power consumption and noise are highly reduced through the optimized design of unique clamping mechanism, reducing the number of hydraulic pump motor, dual torque hydraulic motor and the optimized design of hydraulic system. And the back-pressure is minimized using LM Guide to the sliding part of the injection unit.

Remote Control
The complete remote control is possible through electro-magnetic proportional control
valves for clamping and screw back pressures, linear potentiometer for ejecting, pressure switch & timer for nozzle movement, and solenoid valve for torque selection. 
 
Closed Loop Control 
Precise molding with zero scrap is possible through HICOM-4000 controller with statistical process control and user friendly 10.4 TFT Color LCD featuring IMPACT auto-tuned PID closed loop, which controls injection speed, pressure and temperature.

Easy Maintenance
Two-platen machines are designed for easy maintenance as adopting screw swiveling device of combined the moving cylinder with the connection part of injection unit, easy nozzle center adjustment, improved heater wiring and automatic grease supply unit for clamping unit.
