CLAMPING UNIT
- FEA designed double-toogle five-joint clamping machinery
- High rigidity mould platen with enlarged space between tie bar
- Mould Platen with both T-slot and mould mounting holes
- Movable platen supported by the adjustable slide system which improves platen parallelism and life time of tie bar and mould
- Optimized lubrication system ensuring precision clamping and prolonging the life time of the clamping
- Special design of hydraulic oil cylinder for High speed action
- High precision auto-clamping function according to the clamping force settled
- Oilless bush on the bearing parts prolonging the life time of toggle and tie bar


INJECTION UNIT
- High quality linear motion(LM)guide ensure injection smoothly and accurately
- High speed and high pressure adopt special injection design, improving injection speed
- The barrel of injection setting can be disassembled randomly,after taking the quick connectors and it is easy for maintance.
- Twin nozzle cylinder ensures more even and stable structure
- Specific screw and barrel designs are available for processing different material requirements


HYDRAULIC SYSTEM
- High capacity feedback proportional valve control the pressure and flow separately from L V D T, stability and high sensitivity speed
- Adopt Germany Rexroth variable pump,energy-saving,stability
- Adopt Italy Gefran servo hydraulic system
- The servo energy-saving machines are equipped with rotary encoder and pressrue sensor, and both of them had feed back of flow and pressrue,through changing the speed and torque,high quality synchronous servo motor makes corresponding flow and pressure adjustments to reach the effects of close-loop precisionand energy saving.It control the hydraulic oil temperature reasonable,prolong the using life and save water.
- High speed and high pressure controlled by clamping and injection hydraulic system
- Adopt the special hydraulic syetem to protect the specision mould.
- The proportional back pressure valves adopted ,with easy operation and accurate control
- Butter and thin oil in dependent lubirication system can lubricate everywhere in the best situation

FEATURES
- A PID temperature control, precise temperature control of barrel.
- There are three or four screws and barrels with optimal design, respectively, nitride, hard plating,
dual-metal, which is suitable for different processes of a variety of plastics. and the choice of product.
- Two-guided guided bar supports, double-balanced rapid injection.
- The high-torque hydraulic motors offer a stable plasticizing capacity, highprecision electronic device position detection enable accurate measurement.
- Multi-injection speed and pressure and multi-level holding pressure settings, switch from the injection time, location, pressure control to ensure the quality of molding.
- Multi-level back-pressure of pre-plastic and pre-speed are computer-controlled, anti- drooling and automated auto purge.
- Expected to prevent cold-start function to ensure that the screw, Liao Tong will not be harmed. Stability of the injection unit.
- Security doors fitted with hydraulic, mechanical and electrical interlocking triple safety device. When the safety door is open, the machine cannot clamp.
- Low pressure mold protection device to prevent damage to platen.
- Plywood, frame, the bridge, and the template attached structure, the finite element analysis.
- Hydraulic ejector, adjustable stroke, and top speed of ejector in and out, for multiple actions.
- Flexible tie bars nut eliminates fatigue fracture; assure the working life of tie bars
- Automatic adjustment. The replacement of different mold, the parameters set by clamping force to achieve the automatic adjustment.
- High-precision electronic detection device, multi-stage control of opening stoke, speed and location, location accuracy.

ADVANTAGE OF SERVO MOTOR INJECTION MACHINE
Strong Technical design ability, Stable quality, and large production capability, Famous brand.LonGSHENG servo energy saving Injection Molding Machine, equipped with high performance servo motor controlling system, the machine's output power can vary in accordance with the loading changes, which reduce energy consumption and noise. The motor rotates at lower speed in holding pressure stage, an doesn't work in cooling time.
The Performance of servo energy-saving molding machine:
- Servo motor can optimize the match of energy demand and realize automatic adjustments.
- It can improve injection precision
- It can greatly save power and water, resulting in environment-protection and energy-saving
- Quick response and low noise.
