•High speed CPU increases capacity for memory to meet the requirements of system control. Injection process also can be shown with graphic recording, makes it more easy for injection technique adjustment.
•It can store injection material information for 200 sets of moulds. Mould information could be selected, duplicated or removed conveniently. SD card can be used to read & save mould data, which is conducive for large-scale production management.
•With network communication port, it can realize the network management of injection molding machine. The work state of production and the factory can be monitored, to achieve the fully automation of production.
•Automatic detection of perfect function and a large number of internal parameters help to adjust the machine to the best state.
•Six stages material injection speeds and pressure, three stages pressure holding speed and pressure, and two stages material molten speed and pressure control can meet all complicated process requirement of products.
•Fuzzy temperature control is used. High and low temperature deviation alarm and thermocouple disconnection detection functions are available.
•Function to prevent cold material start-up.
•Mould clamping, injection, ejector adopt high precision electronic meter for position measuring. The position setting precision is up to 0.lmm.
•Push-out stay, ejector shock and multi push-out functions are available. Ejector forward and backward speed, pressure can be set separately in two stage.
•Counting of forming can be matched with automatic stop function for convenient production management.
•Default monitor: When machine works in automatic mode, computer may monitor the working condition in each period and judge if products and machine are normal or not.
•Computer controlled automatic lubrication devices: According to times of opening and clamping mould, lubricating oil output can be adjusted conveniently through computer.
•Automatic mould adjusting function. Input directly clamping pressure, the computer could automatically finish mold thickness adjustment.
•Information setting can be protected to prevent improper modification.

Clamping System

•Five pivots double toggle mould clamping mechanism is featured with fast opening and clamping, stable and energy saving.
•Differential fast mould clamping device effectively reduces cycle time and increases working efficiency of the machine.
•Reliable low pressure protection function greatly prolongs the service life of the mould.
•T-Slot Platen makes fixing the mould in the machine more convenient.

Injection System

Superior and efficient separating screw and high mixing screw increase the range of material used, and guarantee molten material to be uniform and stable.

Superior and efficient separating screw and high mixing screw increase the range of material used, and guarantee molten material to be uniform and stable.

Machine above 250T adopts double injection cylinders to prevent injection nozzle displacement and avoid material leakage.

Lubrication System

·Major friction parts are equipped with lubrication points. Central oil supply system is used for hinges. Electric lubricant pump controlled by computer sends automatically lubricating oil (grease) to lubrication points. Lubrication is simple and high efficient.
·Intelligent volumetric centralized lubricating system, controlled by computer, sends quantitatively lubricating oil (grease) to wearing points, and guarantees that the key carrying surfaces are lubricated reliably. The repair is visual, convenient and fast. The service life of the machine is longer.
